Cache

To enable faster data access from disk storage, the following two types of caching are performed:

???Posted-write caching. The controller writes user data in the cache memory on the module rather than directly to the drives. Later, when the storage system is idle, the controller writes the data to the drive array.

???Read-ahead caching. The controller detects sequential array access, reads ahead into the next sequence of data, and stores the data in the read-ahead cache. Then, if the next read access is for cached data, the controller immediately loads the data into the system memory, avoiding the latency of a disk access.

Transportable CompactFlash

During a power loss or array controller failure, data stored in cache is saved off to non-volatile memory (CompactFlash). This data is then written to disk after the issue is corrected. To protect against writing incomplete data to disk, the image stored on the CompactFlash is verified before committing to disk.

In single-controller configurations, if the controller has failed or does not start, and the Cache Status LED is on or blinking, the CompactFlash will need to be transported to a replacement controller to recover data not flushed to disk. (See Controller failure in a single-controller configuration for more information.)

CompactFlash

HP StorageWorks Carrier-Grade 2324fc Modular Smart Array user guide 19

CAUTION: To preserve the existing data stored in the CompactFlash, you must transport the CompactfFash from the failed controller to the replacement controller using a procedure outlined in the HP StorageWorks 2312fc/2324fc controller replacement instructions, shipped with the replacement controller. Failure to use this procedure will result in the loss of data stored in the cache module. The CompactFlash must stay with the same enclosure. If the CompactFlash is used/installed in a different enclosure, data loss/data corruption will occur.

IMPORTANT: In dual controller configurations, there is no need to transport a failed controller???s cache to a replacement controller because the cache is duplicated between the controllers.

Super-capacitor pack

To protect RAID controller cache in case of power failure, the MSA2324fc is equipped with super-capacitor technology. The super-capacitor pack and CompactFlash memory in each controller module provide unlimited cache memory backup time. The super-capacitor pack provides energy for backing up unwritten data in the write cache to the CompactFlash in the event of a power failure. Unwritten data in CompactFlash memory is automatically committed to disk media when power is restored. While the cache is being maintained by the super-capacitor, the Cache Status LED flashes at a rate of 1/10 second on and 9/10 second off.

3 Installing the enclosures

Installation checklist

The following table outlines the steps required to install the enclosures and initially configure the system. To ensure a successful installation, perform the tasks in the order they are presented.

NOTE: For help with installing your MSA2000 product, also see the MSA2000 Software Support/Documentation CD shipped with your product.

HP StorageWorks Carrier-Grade 2324fc Modular Smart Array user guide 21

Connecting controller and MSA2000 3.5 12-drive enclosures

You can connect up to three MSA2000 3.5 12-drive enclosures to an MSA2324fc. The cabling diagrams shown in this section show the recommended fault-tolerant cabling patterns.

IMPORTANT: Connecting an MSA2000 3.5 12-drive enclosure to an MSA2324fc requires mini SAS to SAS cables. Check the QuickSpecs for an updated list of supported cables. QuickSpecs can be found from your HP MSA products page at http://www.hp.com/go/msa. Select MSA SAN Arrays, and then select your product. The link for QuickSpecs is on the right.

IMPORTANT: The MSA2324fc can also be attached to an MSA70 that is running firmware version 2.18 or later. For information about the MSA70, see the HP StorageWorks 70 Modular Smart Array Enclosure user guide located on the MSA2000 Software Support/Documentation CD shipped with your product or at http://hp.com/support/manuals.

When connecting multiple drive enclosures, use reverse cabling to ensure the highest level of fault tolerance. Controllers and I/O (expansion) modules are identified by <enclosure-ID><controller-ID>. For example, Figure 3 shows controller 1A connected to I/O module 2A, and the chain of connections continuing down. Controller 1B is connected to the lower module (B) of the last drive enclosure in the chain, with connections moving in the opposite direction.

NOTE: For clarity, the schematic illustrations of the controllers shown in this section show only relevant details such as expansion ports. For detailed illustrations showing all components, see Rear panel components.

22 Installing the enclosures

Testing enclosure connections

1. Press the power switches at the back of each drive enclosure to On.

IMPORTANT: This ensures that the disks in the enclosures have enough time to completely spin up before being scanned by the RAID modules in the controller enclosure.

While enclosures power up, their LEDs blink. After the LEDs stop blinking, if no LEDs on the front and back of the enclosure are amber, the power-on sequence is complete and no faults have been detected.

For a description of LED behavior and status, see LED descriptions.

2.Press the power switches at the back of the controller enclosure to On.

Depending on the number and type of drives in the system, it can take several minutes for the system to power up.

If the enclosure???s power-on sequence succeeds as described in Step 1, the system is ready to use.

Obtaining IP values

NOTE: For help with configuring your MSA2000 product, also see the MSA2000 Software Support/Documentation CD shipped with your product.

Setting management port IP addresses using DHCP

1.Look in the DHCP server???s pool of leased addresses for two IP addresses assigned to ???HP StorageWorks MSA Storage.???

2.Use a network management utility to discover ???HP StorageWorks MSA2300fc??? storage devices on the local LAN through SNMP.

3.Use a ping broadcast to try to identify the device through the host???s ARP table.

If you do not have a DHCP server, you will need to ask your system administrator to allocate two IP addresses and set them using the CLI during initial configuration (see Setting management port IP addresses using the CLI).

Setting management port IP addresses using the CLI

NOTE: If you used DHCP to set the IP addresses, you do not have to set them using the CLI as described in this section.

Ethernet Management ports on controller module A and controller module B are configured with the following default values:

???Management Port IP Address: 10.0.0.2 (controller A), 10.0.0.3 (controller B)

???IP Subnet Mask: 255.255.255.0

???Gateway IP Address: 10.0.0.1

If the default IP addresses are not compatible with your network, you must set an IP address for each management port using the command-line interface (CLI) embedded in each controller module. The CLI enables you to access the system using RS-232 communication and terminal emulation software.

Use the CLI commands described in the steps below to set the IP address for the Ethernet management port on each controller module.

Once new IP addresses are set, you can change them as needed using SMU.

NOTE: Changing IP settings can cause management hosts to lose access to the storage system.

24 Installing the enclosures

1.From your network administrator obtain an IP address, subnet mask, and gateway address for controller A and controller B.

2.Use the provided micro-DB9 serial cable to connect controller A to a serial port on a host computer.

Your package contents include a micro-DB9-to-DB9 serial cable. If necessary, use a DB9-to-DB25 adapter (not included) for connecting the serial cable to a DB25 serial port on the host computer.

3.Start and configure a terminal emulator, such as HyperTerminal or VT-100, using the display settings in Table 3 and the connection settings in Table 4.

Table.3 Terminal emulator display settings

4. In the terminal emulator, connect to controller A. Table 4 Terminal emulator connection settings

5. Press Enter to display the CLI prompt (#).

HP StorageWorks Carrier-Grade 2324fc Modular Smart Array user guide 25

6.At the prompt, type the following command to set the values you obtained in Step 1 for each Ethernet management port, first for controller A and then for controller B:

set network-parameters ip address netmask netmask gateway gateway controller a|b

where:

???address is the IP address of the controller

???netmask is the subnet mask

???gateway is the IP address of the subnet router

???a|b specifies the controller whose network parameters you are setting

For example:

#set network-parameters ip 192.168.0.10 netmask 255.255.255.0 gateway 192.168.0.1 controller a

#set network-parameters ip 192.168.0.11 netmask 255.255.255.0 gateway 193.168.0.1 controller b

7.Type the following command to verify the new IP addresses:

show network-parameters

Network parameters, including the IP address, subnet mask, and gateway address are displayed for each controller.

a.From the CLI you can use the PING command to verify network connectivity For example:

# ping 16.125.12.1

Info: Pinging 16.125.12.1 with 4 packets.

Success: Command completed successfully. The remote computer responded with 4 packets.

8.Disconnect from the CLI and exit the emulator.

9.In the host computer's command window, type the following command to verify Ethernet connectivity, first for controller A and then for controller B:

ping IP-address

If you cannot your access your system for at least three minutes after changing the IP address, your network might require you to restart the management controller using the serial CLI. When you restart a management controller, communication with it is temporarily lost until it successfully restarts.

Type the following command to restart the management controller on both controllers:

restart mc both

4 Connecting hosts

Host system requirements

Data hosts connected to MSA2324fc arrays must meet the following requirements:

???Depending on your system configuration, data host operating systems may require that multipathing is supported.

If fault tolerance is required, then multipathing software may be required. Host-based multipath software should be used in any configuration where two logical paths between the host and any storage volume may exist at the same time. This would include most configurations where there are multiple connections to the host or multiple connections between a switch and the storage.

To obtain the MSA2000 Family MPIO DSM, go to the HP MSA products page at http://www.hp.com/go/msa. Select MSA SAN Arrays, select your product, and go to Related products.

???To prevent Microsoft Windows 2003 data hosts from displaying the Found New Hardware Wizard when the storage system is discovered, install the MSA2000 Family SCSI Enclosure Services driver. Download MSA2000 Family SCSI Enclosure Services (SES) driver package from http://www.hp.com/go/msa. Select MSA SAN Arrays, select your product, and go to Related products.

NOTE: The MSA2000 Family SCSI Enclosure Services driver is required for Microsoft Windows 2003.

Connecting remote management hosts

The management host directly manages systems out-of-band over an Ethernet network.

1.Connect an Ethernet cable to the Ethernet management port on each controller.

2.Connect the other end of each Ethernet cable to a network that your management host can access (preferably on the same subnet).

NOTE: Connections to this device must be made with shielded cables with metallic RFI/EMI connector hoods in order to maintain compliance with FCC Rules and Regulations.

28 Connecting hosts

5 Basic operation

Powering on/powering off

Before powering on the enclosure for the first time:

???Install all hard drives in the enclosure so that the connected host controller can identify and configure them at power-up.

???Connect the cables and power cords to the enclosure as explained in the Installation Poster.

???Generally when powering up, make sure to power up the enclosures and associated data host in the following order:

???Drive enclosures first

???Controller enclosure next

???Data hosts last (if they are powered down for maintenance purposes)

To power on the system:

1.Press the power switches at the back of each drive enclosure to the On position.

2.Press the power switches at the back of the controller enclosure to the On position.

To power off the system:

1.Stop all I/O from hosts to the system.

2.Use SMU to shut down both controllers. See the SMU online help or CLI reference guide for information on shutting down controller.s

Wait until SMU indicates that processing is complete.

3.Press the power switches at the back of the controller enclosure to the Off position.

4.Press the power switches at the back of each drive enclosure to the Off position.

Updating firmware

After installing the hardware and powering up the enclosure for the first time, be sure to verify that the controllers and drive enclosures have the latest firmware. SMU enables you to view the software, hardware, and other version information for each controller and the enclosures.

To view controller version information, in the Configuration View panel, right-click the system, select View > Overview, and select the Versions button in the System Overview Table. To view drive enclosure information, in the Configuration View panel, right-click the enclosure and select View > Overview. The enclosure firmware is listed as EMP A Revision and EMP B Revision.

For software and firmware updates, including language packages and firmware update instructions, go to http://www.hp.com/go/msa. Select MSA SAN Arrays, select your product, and go to Support.

Selecting an appropriate time to perform the online upgrade

To ensure the success of an online upgrade, selecting the appropriate time is essential. Selecting a period of low I/O activity will ensure the upgrade completes as quickly as possible, and will avoid disruptions to host and applications due to timeouts. Attempting to upgrade a storage system that is in the middle of processing a large I/O intensive batch job will likely cause hosts to lose connectivity with the storage system. Consequently, finding an appropriate time for the upgrade is very important.

For software and firmware updates, go to http://www.hp.com/go/msa. Select MSA SAN Arrays, select your product, and go to Support.

For detailed steps on updating the firmware, see the reference guide or the CLI reference guide. For information on logging into SMU, see Configuring a system for the first time.

Changing the system date and time

You can change the storage system's date and time, which are displayed in the System Status panel. It is important to set the date and time so that entries in system logs and event-notification email messages have correct time stamps.

You can set the date and time manually or configure the system to use Network Time Protocol (NTP) to obtain them from a network-attached server. When NTP is enabled, and if an NTP server is available, the system time and date can be obtained from the NTP server. This allows multiple storage devices, hosts, log files, and so forth to be synchronized. If NTP is enabled but no NTP server is present, the date and time are maintained as if NTP was not enabled.

NTP server time is provided in Universal Time (UT), which provides several options:

???If you want to synchronize the times and logs between storage devices installed in multiple time zones, set all the storage devices to use UT.

???If you want to use the local time for a storage device, set its time zone offset.

???If a time server can provide local time rather than UT, configure the storage devices to use that time server, with no further time adjustment.

To use manual date and time settings

1.In the Configuration View panel, right-click the system and select Configuration > System Settings > Date, Time. The date and time options appear.

2.Set the options:

???Time. Enter the time in the format hh:mm:ss.

???Month.

???Day.

???Year. Enter the year using four digits.

???NTP. Select Disabled.

3.Click Set Time Values.

To obtain the date and time from an NTP server

8 Troubleshooting

Fault isolation methodology

The MSA2000 Family storage system provides many ways to isolate faults within the system. This section presents the basic methodology used to locate faults and the associated FRUs.

The basic fault isolation steps are:

???Gather fault information, including using system LEDs

???Determine where in the system the fault is occurring

???Review event logs

???If required, isolate the fault to a data path component

Gather fault information

When a fault occurs, it is important to gather as much information as possible. Doing so will help you determine the correct action needed to remedy the fault.

Begin by reviewing the reported fault. Is the fault related to an internal data path or an external data path? Is the fault related to a hardware component such as a drive module, controller module, or power supply? By isolating the fault to one of the components within the storage system, you will be able to determine the necessary action more rapidly.

Determine where the fault is occurring

Once you have an understanding of the reported fault, review the enclosure LEDs. The enclosure LEDs are designed to alert users of any system faults and might be what alerted the user to a fault in the first place.

When a fault occurs, the Fault ID status LED on an enclosure???s right ear (see Front panel components) illuminates. Check the LEDs on the back of the enclosure to narrow the fault to a FRU, connection, or both. The LEDs also help you identify the location of a FRU reporting a fault.

Use SMU to verify any faults found while viewing the LEDs. SMU is also a good tool to use in determining where the fault is occurring if the LEDs cannot be viewed due to the location of the system. SMU provides you with a visual representation of the system and where the fault is occurring. It can also provide more detailed information about FRUs, data, and faults.

Review the event logs

The event logs record all system events. It is very important to review the logs, not only to identify the fault, but also to search for events that might have caused the fault to occur. For example, a host could lose connectivity to a virtual disk if a user changes channel settings without taking the storage resources assigned to it into consideration. In addition, the type of fault can help you isolate the problem to hardware or software.

Isolate the fault

Occasionally it might become necessary to isolate a fault. This is particularly true with data paths due to the number of components the data path consists of. For example, if a host-side data error occurs, it could be caused by any of the components in the data path: controller module, cable, or data host.

If the enclosure does not initialize

It may take up to two minutes for the enclosures to initialize. If the enclosure does not initialize:

???Perform a rescan.

???Power cycle the system.

???Make sure the power cord is properly connected and check the power source that it is connected to.

???Check the event log for errors.

HP StorageWorks Carrier-Grade 2324fc Modular Smart Array user guide 43

Correcting enclosure IDs

When installing a system with drive enclosures attached, the enclosure IDs might not agree with the physical cabling order. This is because the controller might have been previously attached to some of the same enclosures during factory testing and it attempts to preserve the previous enclosure IDs if possible. To correct this condition, make sure that both controllers are up and perform a rescan using SMU or the CLI. This will reorder the enclosures, but can take up to two minutes for the enclosure IDs to be corrected.

To perform a rescan using the CLI, type the following command:

rescan

To rescan using SMU:

1.Verify that both controllers are operating normally.

2.In the Configuration View panel, right-click the system and select Tools > Rescan Disk Channels.

3.Click Rescan.

Controller failure in a single-controller configuration

Cache memory is flushed to CompactFlash in the case of a controller failure or power loss. During the write to CompactFlash process only the components needed to write the cache to the CompactFlash are powered by the super-capacitor. This process typically takes 60 seconds per 1 Gbyte of cache. After the cache is copied to CompactFlash, the remaining power left in the super-capacitor is used to refresh the cache memory. While the cache is being maintained by the super-capacitor, the Cache Status LED flashes at a rate of 1/10 second off and 9/10 second on.

IMPORTANT: Transportable cache only applies to single-controller configurations. In dual controller configurations, there is no need to transport a failed controller???s cache to a replacement controller because the cache is duplicated between the controllers.

If the controller has failed or does not start, is the Cache Status LED on/blinking?

Transporting Cache

To preserve the existing data stored in the CompactFlash, you must transport the CompactFlash from the failed controller to a replacement controller using a procedure outlined in the HP StorageWorks 2312fc/2324fc controller replacement instructions, shipped with the replacement controller. Failure to use this procedure will result in the loss of data stored in the cache module.

CAUTION: Remove the controller only after the copy process is complete, which is indicated by the Cache Status LED being off.

48 Troubleshooting

Isolating a host-side connection fault

During normal operation, when a controller module host port is connected to a data host, the port???s host link status LED and host link activity LED are green. If there is I/O activity, the host activity LED blinks green. If data hosts are having trouble accessing the storage system, and you cannot locate a specific fault or cannot access the event logs, use the following procedure. This procedure requires scheduled downtime.

IMPORTANT: Do not perform more than one step at a time. Changing more than one variable at a time can complicate the troubleshooting process.

1.Halt all I/O to the storage system.

2.Check the host activity LED.

If there is activity, halt all applications that access the storage system.

3.Reseat the SFP and FC cable. Is the host link status LED on?

???Yes ??? Monitor the status to ensure that there is no intermittent error present. If the fault occurs again, clean the connections to ensure that a dirty connector is not interfering with the data path.

???No ??? Proceed to the next step.

4.Move the SFP and cable to a port with a known good link status.

This step isolates the problem to the external data path (SFP, host cable, and host-side devices) or to the controller module port.

Is the host link status LED on?

???Yes ??? You now know that the SFP, host cable, and host-side devices are functioning properly. Return the SFP and cable to the original port. If the link status LED remains off, you have isolated the fault to the controller module???s port. Replace the controller module.

???No ??? Proceed to the next step.

5.Swap the SFP with the known good one. Is the host link status LED on?

???Yes ??? You have isolated the fault to the SFP. Replace the SFP.

???No ??? Proceed to the next step.

6.Re-insert the original SFP and swap the cable with a known good one. Is the host link status LED on?

???Yes ??? You have isolated the fault to the cable. Replace the cable.

???No ??? Proceed to the next step.

7.Replace the HBA with a known good HBA, or move the host side cable and SFP to a known good HBA.

Is the host link status LED on?

???Yes ??? You have isolated the fault to the HBA. Replace the HBA.

???No ??? It is likely that the controller module needs to be replaced.

8.Move the cable and SFP back to its original port. Is the host link status LED on?

???No ??? The controller module???s port has failed. Replace the controller module.

???Yes ??? Monitor the connection for a period of time. It may be an intermittent problem, which can occur with SFPs, damaged cables, and HBAs.

HP StorageWorks Carrier-Grade 2324fc Modular Smart Array user guide 49

Isolating a controller module expansion port connection fault

During normal operation, when a controller module???s expansion port is connected to a drive enclosure, the expansion port status LED is green. If the connected port???s expansion port LED is off, the link is down. Use the following procedure to isolate the fault.

This procedure requires scheduled downtime.

NOTE: Do not perform more than one step at a time. Changing more than one variable at a time can complicate the troubleshooting process.

1.Halt all I/O to the storage system.

2.Check the host activity LED.

If there is activity, halt all applications that access the storage system.

3.Reseat the expansion cable.

Is the expansion port status LED on?

???Yes ??? Monitor the status to ensure there is no intermittent error present. If the fault occurs again, clean the connections to ensure that a dirty connector is not interfering with the data path.

???No ??? Proceed to Step 4.

4.Move the expansion cable to a port on the RAID enclosure with a known good link status.

This step isolates the problem to the expansion cable or to the controller module???s expansion port. Is the expansion port status LED on?

???Yes ??? You now know that the expansion cable is good. Return cable to the original port. If the expansion port status LED remains off, you have isolated the fault to the controller module???s expansion port. Replace the controller module.

???No ??? Proceed to the next step.

5.Move the expansion cable back to the original port on the controller enclosure.

6.Move the expansion cable on the drive enclosure to a known good expansion port on the drive enclosure.

Is the expansion port status LED on?

???Yes ??? You have isolated the problem to the drive enclosure???s port. Replace the expansion module.

???No ??? Proceed to Step 7.

7.Replace the cable with a known good cable, ensuring the cable is attached to the original ports used by the previous cable.

Is the host link status LED on?

???Yes ??? Replace the original cable. The fault has been isolated.

???No ??? It is likely that the controller module needs to be replaced

Resolving voltage and temperature warnings

1.Check that all of the fans are working by making sure each power supply???s DC Voltage/Fan Fault/Service Required LED is off or by using SMU to check for yellow yield icon hardware warnings. (In the Configuration View panel, right click the enclosure and click View > Overview.)

2.Make sure that all modules are fully seated in their slots and that their latches are locked.

3.Make sure that no slots are left open for more than two minutes.

If you need to replace a module, leave the old module in place until you have the replacement or use a blank module to fill the slot. Leaving a slot open negatively affects the airflow and can cause the enclosure to overheat.

4.Try replacing each power supply one at a time.

5.Replace the controller modules one at a time.

50 Troubleshooting

Sensor locations

The storage system monitors conditions at different points within each enclosure to alert you to problems. Power, cooling fan, temperature, and voltage sensors are located at key points in the enclosure. In each controller module and expansion module, the enclosure management processor (EMP) monitors the status of these sensors to perform SCSI enclosure services (SES) functions.

The following sections describe each element and its sensors.

Power supply sensors

Each enclosure has two fully redundant power supplies with load-sharing capabilities. The power supply sensors described in the following table monitor the voltage, current, temperature, and fans in each power supply. If the power supply sensors report a voltage that is under or over the threshold, check the input voltage.

Table 6 Power supply sensors

Cooling fan sensors

Each power supply includes two fans. The normal range for fan speed is 4000 to 6000 RPM. When a fan???s speed drops below 4000 RPM, the EMP considers it a failure and posts an alarm in the storage system???s event log. The following table lists the description, location, and alarm condition for each fan. If the fan speed remains under the 4000 RPM threshold, the internal enclosure temperature may continue to rise. Replace the power supply reporting the fault.

Table 7 Cooling fan sensor descriptions

During a shutdown, the cooling fans do not shut off. This allows the enclosure to continue cooling.

Temperature sensors

Extreme high and low temperatures can cause significant damage if they go unnoticed. Each controller module has six temperature sensors. Of these, if the CPU or FPGA temperature reaches a shutdown value, the controller module is automatically shut down. Each power supply has one temperature sensor.

When a temperature fault is reported, it must be remedied as quickly as possible to avoid system damage. This can be done by warming or cooling the installation location.

Table 8 Controller module temperature sensors

HP StorageWorks Carrier-Grade 2324fc Modular Smart Array user guide 51

Table 8 Controller module temperature sensors (continued)

When a power supply sensor goes out of range, the Fault/ID LED illuminates amber and an event is logged to the event log.

Table 9 Power supply temperature sensors

Power supply module voltage sensors

Power supply voltage sensors ensure that an enclosure???s power supply voltage is within normal ranges. There are three voltage sensors per power supply.

B Environmental requirements and specifications

Safety requirements

Install the system in accordance with the local safety codes and regulations at the facility site. Follow all cautions and instructions marked on the equipment.

Site requirements and guidelines

The following sections provide requirements and guidelines that you must address when preparing your site for the installation.

When selecting an installation site for the system, choose a location not subject to excessive heat, direct sunlight, dust, or chemical exposure. These conditions greatly reduce the system???s longevity and might void your warranty.

Site wiring and AC power requirements

The following are required for all installations using AC power supplies:

???All AC mains and supply conductors to power distribution boxes for the rack-mounted system must be enclosed in a metal conduit or raceway when specified by local, national, or other applicable government codes and regulations.

???Ensure that the voltage and frequency of your power source match the voltage and frequency inscribed on the equipment???s electrical rating label.

???To ensure redundancy, provide two separate power sources for the enclosures. These power sources must be independent of each other, and each must be controlled by a separate circuit breaker at the power distribution point.

???The system requires voltages within minimum fluctuation. The customer-supplied facilities??? voltage must maintain a voltage with not more than ?? 5 percent fluctuation. The customer facilities must also provide suitable surge protection.

???Site wiring must include an earth ground connection to the AC power source. The supply conductors and power distribution boxes (or equivalent metal enclosure) must be grounded at both ends.

???Power circuits and associated circuit breakers must provide sufficient power and overload protection. To prevent possible damage to the AC power distribution boxes and other components in the rack, use an external, independent power source that is isolated from large switching loads (such as air conditioning motors, elevator motors, and factory loads).

Site wiring and DC power requirements

The following are required for all installations using DC power supplies:

???All DC mains and supply conductors to power distribution boxes for the rack-mounted system must comply with local, national, or other applicable government codes and regulations.

???Ensure that the voltage of your power source matches the voltage inscribed on the equipment???s electrical label.

???To ensure redundancy, provide two separate power sources for the enclosures. These power sources must be independent of each other, and each must be controlled by a separate circuit breaker at the power distribution point.

???The system requires voltages within minimum fluctuation. The customer-supplied facilities??? voltage must maintain a voltage within the range specified on the equipment???s electrical rating label. The customer facilities must also provide suitable surge protection.

???Site wiring must include an earth ground connection to the DC power source. Grounding must comply with local, national, or other applicable government codes and regulations.

???Power circuits and associated circuit breakers must provide sufficient power and overload protection.

HP StorageWorks Carrier-Grade 2324fc Modular Smart Array user guide 61

Weight and placement guidelines

Refer to Physical requirements for detailed size and weight specifications.

???The weight of an enclosure depends on the number and type of modules installed.

???Ideally, use two people to lift an enclosure. However, one person can safely lift an enclosure if its weight is reduced by removing the power and cooling modules and drive modules.

???Do not place enclosures in a vertical position. Always install and operate the enclosures in a horizontal orientation.

???When installing enclosures in a rack, make sure that any surfaces over which you might move the rack can support the weight. To prevent accidents when moving equipment, especially on sloped loading docks and up ramps to raised floors, ensure you have a sufficient number of helpers. Remove obstacles such as cables and other objects from the floor.

???To prevent the rack from tipping and to minimize personnel injury in the event of a seismic occurrence, securely anchor the rack to a wall or other rigid structure that is attached to both the floor and to the ceiling of the room.

Electrical guidelines

???These enclosures work with single-phase power systems having an earth ground connection. To reduce the risk of electric shock, do not plug an enclosure into any other type of power system. Contact your facilities manager or a qualified electrician if you are not sure what type of power is supplied to your building.

???Enclosures are shipped with a grounding-type (three-wire) power cord. To reduce the risk of electric shock, always plug the cord into a grounded power outlet.

???Do not use household extension cords with the enclosures. Not all power cords have the same current ratings. Household extension cords do not have overload protection and are not meant for use with computer systems.

Ventilation requirements

Refer to Environmental requirements for detailed environmental requirements.

???Do not block or cover ventilation openings at the front and rear of an enclosure. Never place an enclosure near a radiator or heating vent. Failure to follow these guidelines can cause overheating and affect the reliability and warranty of your enclosure.

???Leave a minimum of 6 inches (15 cm) at the front and back of each enclosure to ensure adequate airflow for cooling. No cooling clearance is required on the sides, top, or bottom of enclosures.

???Leave enough space in front and in back of an enclosure to allow access to enclosure components for servicing. Removing a component requires a clearance of at least 15 inches (37 cm) in front of and behind the enclosure.

Cabling requirements

???Keep power and interface cables clear of foot traffic. Route cables in locations that protect the cables from damage.

???Route interface cables away from motors and other sources of magnetic or radio frequency interference.

???Stay within the cable length limitations.

Management host requirements

A local management host with at least one serial port connection is recommended for the initial installation and configuration of a controller enclosure. After you configure one or both of the controller modules with an Internet Protocol (IP) address, you then use a remote management host on an Ethernet network to configure, manage, and monitor.

62 Environmental requirements and specifications

NOTE: Connections to this device must be made with shielded cables with metallic RFI/EMI connector hoods in order to maintain compliance with FCC Rules and Regulations.

Physical requirements

The floor space at the installation site must be strong enough to support the combined weight of the rack, controller enclosures, expansion enclosures, and any additional equipment. The site also requires sufficient space for installation, operation, and servicing the enclosures, and also requires sufficient ventilation to allow a free flow of air to all enclosures.

Table 14 and Table 15 list enclosure dimensions and weights. Weights are based on an enclosure having 12 drive modules, two controller or expansion modules, and two power supplies installed.

Electrical requirements

Site wiring and power requirements

Each enclosure has two power and cooling modules for redundancy. If full redundancy is required, use a separate power source for each module. The AC power supply unit in each power and cooling module is auto-ranging and is automatically configured to an input voltage range from 88???264 VAC with an input frequency of 47???63 Hz. The power and cooling modules meet standard voltage requirements for both U.S. and international operation. The power and cooling modules use standard industrial wiring with line-to-neutral or line-to-line power connections.

Power cord requirements

Each enclosure is shipped with two AC power cords that are appropriate for use in a typical outlet in the destination country. Each power cord connects one of the power and cooling modules to an independent, external power source. To ensure power redundancy, connect the two power cords to two separate circuits; for example, to one commercial circuit and one uninterruptible power source (UPS).

C Electrostatic discharge

Preventing electrostatic discharge

To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage:

???Avoid hand contact by transporting and storing products in static-safe containers.

???Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

???Place parts on a grounded surface before removing them from their containers.

???Avoid touching pins, leads, or circuitry.

???Always be properly grounded when touching a static-sensitive component or assembly.

Grounding methods to prevent electrostatic discharge

Several methods are used for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

???Use a wrist strap connected by a ground card to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm ?? 10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

???Use heel straps, toe straps or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats.

???Use conductive field service tools.

???Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part.

For more information on static electricity or assistance with product installation, contact an authorized reseller.

D Regulatory compliance and safety

Regulatory compliance

Federal Communications Commission notice

Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic devices, including computers, generate RF energy incidental to their intended function and are, therefore, covered by these rules. These rules place computers and related peripheral devices into two classes, A and B, depending upon their intended installation. Class A devices are those that may reasonably be expected to be installed in a business or commercial environment. Class B devices are those that may reasonably be expected to be installed in a residential environment (i.e., personal computers). The FCC requires devices in both classes to bear a label indicating the interference potential of the device as well as additional operating instructions for the user.

The rating label on the device shows which class (A or B) the equipment falls into. Class B devices have an FCC logo or FCC ID on the label. Class A devices do not have an FCC logo or FCC ID on the label. Once the class of the device is determined, refer to the following corresponding statement.
