Before you Begin

Note: The Escalade Serial ATA controller can be used with either serial or parallel drives. If using the controller with parallel drives the CBL-P-SATA (Parallel to Serial Driver Converter) must be used in conjunction.

The advantage of using the Escalade SerialATA Controller with parallel drives is the simpler, longer cable and increased airflow.

Tools Required

???An ESD grounding strap or mat

???Standard hand tools to open your system???s case and install the Escalade ATA RAID Controller into an available PCI expansion slot.

System Requirements

The Escalade ATA RAID Controller requires a workstation-class or server-class CPU whose bus complies with PCI 2.2 standards, and a PCI slot that meets the Plug and Play and PC99 specifica- tions. The ATA RAID Controller may be connected to up to two, four, eight, or twelve IDE/ATA drives by the supplied interface cables.

Note: It is recommended that the Escalade 7000 or 8000 card be installed in the 64-bit PCI slot whenever possible for the best performance. The controllers fit in both 32-bit and 64-bit PCI slots with 5V as well as 3.3V. The 12-port

7000 board requires one full size PCI slot.

.

Drives must meet UltraATA-133, UltraATA-100, UltraATA-66 or UltraATA-33 standards (8000 family does not support UltraDMA- 66 or UltraDMA-33 standards), but may be of any capacity or phys- ical form factor. Length of unshielded interface cables may not

Before you Begin

exceed 36??? (91.4 cm) for parallel ATA controllers and 1M (39???) for serial ATA controllers.

Personal Safety

Warning! High voltages may be found inside computer equipment. Before installing any of the hardware in this package or removing the protective covers of any com- puter equipment, turn off power switches and disconnect power cords. Do not reconnect the power cords until you have replaced the covers.

Protecting Equipment and Data

Back up your data! Creating or deleting disk arrays destroys existing files on the member drives. If your drives contain valuable data, back them up and save data elsewhere before changing your array configuration.

ESD Precautions

Standard electrostatic discharge (ESD) precautions must be fol- lowed to avoid damaging computer components and accessories when installing or removing the EscaladeATA RAID Controller.

???When the case of your computer is open and its internal parts are exposed, don???t touch any internal part unnecessarily.

???Always wear a grounded strap or work on an ESD-protective mat.

???Don???t remove the ATA RAID Controller from its protective bag until you are properly grounded.

Connect the interface cables to the Escalade ATA RAID Controller

1Connect the interface cables supplied with the product to the ATA RAID Controller. See Figure 1.

Hardware Installation

Note: UltraATA-66, UltraATA-100 and UltraATA- 133 drives require 40-pin, 80-conductor ribbon cables. These cables have color coded ends. For opti- mum performance, the blue end must be connected to the ATA RAID Controller and the black end must be con- nected to the hard drive.

2One edge of each interface cable should have a colored (usually red) line denoting the conductor to Pin 1. Align the ATA RAID Controller so that the colored line is toward the top edge of the controller. Mate the connectors carefully without bending any pins.

3Install the other connectors in the same manner.

Install the Escalade ATA RAID Controller in the computer

1If the computer is running, shut it down. Turn off power to the computer and disconnect the power cord from the outlet.

2Open the computer case according to the manufacturer???s instruc- tions.

3Find the PCI slot you want to use for the ATA RAID Controller.

Hint: Cable routing may be easier if you install the ATA RAID Controller next to an open slot.

4Remove the metal filler bracket for the slot. Save this screw; it will be used to secure the ATA RAID Controller after you have seated it in the slot.

3ware Escalade ATA RAID Controller Installation Guide

Hint: While the ATA RAID Controller runs properly in any PCI slot, not all slots give equal performance due to the architecture of the PCI bus. In our laboratories, we have noticed that the slots closest to the Accelerated Graphics Port (AGP) or in the 64-bit PCI slot typically give the best performance. Our card should fit in both 32-bit and 64-bit PCI slots with 5V as well as with 3.3V.

5Line the ATA RAID Controller up so that all pins make proper contact with the PCI slot pins when pushed into place. The black end rail opposite the metal bracket may be removed if needed to fit the ATA RAID Controller inside the chassis. The short 4-port or 8-port Escalade ATA RAID Controller is keyed to ensure proper installation in a full-sized PCI slot.

6Ensure that the contacts will mate with both grooves in the slot. Press down gently on the edge of theATA RAID Controller directly above the slot until it is fully seated.

7Check that the ATA RAID Controller???s metal bracket covers the hole in the case and secure the bracket with the screw that was used to secure the filler bracket in step 4.

Connect the drives to the interface cables

1Be sure to use the supplied cables. With the higher speeds of UltraATA-133, UltraATA-100 and UltraATA-66, using quality cables is important.

2Before connecting your drives, check your drives??? jumper set- ting. The range of settings provided vary by manufacturer as do the method for adjusting them. Refer to information provided with your drives for the method required to set them. To operate properly, the Escalade ATA RAID Controller requires that drives be set as Single (if available on your drive) or Master.

3If your drives are not already installed in the computer chassis, do so now. Be sure that the drives are connected to the power supply.

Hardware Installation

4For each drive, select the black end of an interface cable not con- nected to the ATA RAID Controller and plug it into the drive or drive carrier. The cable???s colored edge denotes Pin 1 and should be adjacent to the 4-pin power plug.

Note: Continue to page 22 ???Check your installation and close the case???.

1If your drives are not already installed in the computer chassis, install them now. Be sure that the drives are connected to the power supply.

2For each drive, select the end of an interface cable not connected to the ATA RAID Controller and plug it into the drive or drive carrier. One edge of each interface cable connector is keyed to ensure proper installation.

Using parallel ATA-133 or ATA-100 drives with converter kit (CBL-P-SATA)

Note: UltraATA-66 and UltraATA-33 drives are not supported.

1Before connecting your drives, check each drive???s jumper set- ting. The range of settings vary by manufacturer as do the method for adjusting them. Refer to information provided with your drives for the method required to set them. To operate prop- erly, the Escalade ATA RAID Controller requires that drives be set as Single (if available on your drive) or Master.

Hardware Installation

2Install two jumpers on the converter if not already installed. See Figure 3 for location to set jumper settings.

3Connect a Power Converter Adapter to each converter. See Figure 3 for connector locations.

4When you have completed steps 2 and 3 for each converter, install a Converter onto the back of each parallelATA drive. Make sure that each converter is properly aligned and securely pushed in. The converter board???s power connector must be adja- cent to the drive???s power connector. See Figure 3.

Note: The Serial ATA Converter has sharp points. Please use caution when pushing the converter onto the back of the drive.

5Connect the Power Adapter to the power receptacle on the drive.

6If your drives are not already installed in the computer chassis, install them now. Be sure that the drives are connected to the power supply.

7Connect each power adapter to the power supply.

8For each drive, select the end of an interface cable not connected to the ATA RAID Controller and plug it into the Converter.

volumes, and, consequently, they cannot be designated as spares at a later time. If a spare is designated in the BIOS screen, the designa- tion and configuration is in effect from this point on. The spare drive will be displayed as a Hot Spare in the 3DM configuration page.

3DM Configure Page

In order to designate an available drive as a spare from the 3DM configure page, you must ensure that the drive is not a JBOD drive or part of an existing array. To designate a drive as a Hot Spare from this page, you must use one of the two following methods:

Replacing a Defective Drive with a Spare

Replace the drive at the operating system level while the system is powered. This should only be done with an approved and recog- nized hot swap drive-carrier. If you do not use an approved and rec- ognized hot swap drive-carrier, connecting interface cables and power cables can/will crash the system from bus or power supply issues. Select the checkbox next to the drive to be removed and click Remove Drive. Select the same checkbox and then click Add Spare.

Adding a Spare Drive to an Available Port

To add a new spare, follow the same steps except you will not be required to remove a drive.

Invoking the 3ware BIOS tool

Power up or reboot your system. Before the boot phase, wait until you see a screen similar to Figure 4.

3ware Disk Array Configuration Utility

Figure 4. 3ware BIOS Tool

Press Alt-3 immediately to bring up the 3ware Disk Array Config- uration display.

Note: If drives are attached and you do not want to install the 3ware BIOS, press Alt-b to bypass the BIOS installation. This is useful when booting temporarily from another device.

Exiting the 3ware BIOS tool

To save your configuration modifications hit the F8 key. After you have hit the F8 key to commit your changes, a list of affected drives will be displayed and you will be asked to confirm your configura- tion. The booting process will resume.

To exit the 3ware Disk Array Configuration Utility without saving your changes hit Esc.

3ware Escalade ATA RAID Controller Installation Guide

Determining your configuration

Caution: Configuring a disk array writes format-type data onto its member disks and overwrites all the files on those disks. Be sure to back up data that requires retention.

???All supported RAID levels (0,1,5,10) can be created based on the number of drives that theATA RAID Controller supports.

???Multiple arrays of supported RAID levels can be implemented on a single controller based on the number of drives that the ATA RAID Controller supports.

The 3ware Disk Array Configuration main display shows the cur- rent disk drive configuration.

???Available Drives reports independent drives (JBOD) not associ- ated with an array and hot spares.

???Disk Arrays lists any existing arrays along with their member disks.

Creating a disk array

To create an array, first select the drives to be included by navigat- ing the cursor over each drive and pressing Enter (see Figure 7). An asterisk in the left most column indicates the drive is selected. You may include from two to twelve drives in the array by selecting drives from the Available Drives section. To include drives that are part of an existing disk array you must first delete the array.

3ware Disk Array Configuration Utility

Note: Accelerate keys. Anywhere in the BIOS config- uration screen, if a user hits the corresponding accelerate keys, it immediately highlights the appropriate button:

Alt-C for "Create Array" Alt-D for "Delete Array" Alt-M for "Maintain Array" Alt-R for "Rebuild Array"

Figure 7. Selecting Drives for a Mirrored Array

3ware Escalade ATA RAID Controller Installation Guide

Determining your configuration

Hint: The capacity of each drive is limited to the capacity of the smallest drive in the array. The total array capacity is defined as follows:

RAID 0: (the number of drives) X (the capacity of the smallest drive)

RAID 1: the capacity of the smallest drive

RAID 5: (the number of drives - 1) X (capacity of the smallest drive)

RAID10: (the number of drives / 2) X (capacity of smallest drive)

Navigate to the Create Array button after selecting all the drives for the array. Hit Enter to bring up the Create Disk Array display (see Figure 8 and Figure 9 for examples). Check that the proper drives are listed.

Create Disk Array

Note: Creating an array will overwrite existing data on its drives.

Figure 9. Create Disk Array Display, RAID 5 Example

Select RAID configuration

The Escalade ATA RAID Controller gives you a choice of four RAID configurations. Select one.

???Stripe (RAID 0): maximizes performance and capacity through a process called striping. High performance arrays write portions of a single file across multiple drives. There is no fault tolerance.

???Mirror (RAID 1): duplicates or ???mirrors??? the data on both drives. No data will be lost if one of the drives fails.

???RAID 10: combines mirroring and striping, providing both fault tolerance and high performance. RAID 10 arrays require a minimum of four drives. Configurations consist of 4, 6, 8, 10 or 12 drives.

???RAID 5: combines parity data and striping, providing fault toler- ance, high capacity and high storage efficiency. The parity data is distributed across all drives, rather than being concentrated on

3ware Escalade ATA RAID Controller Installation Guide

a single disk. RAID 5 arrays require a minimum of three

drives. Configurations consist of at least 3 drives and up to 12 drives.

3ware Disk Array Configuration

Figure 10. BIOS Initialization Screen for RAID 5

Select striping size

For a RAID 0 or RAID 10 configuration select the striping size. Sizes of 64K, 128K, 256K, 512K or 1M are selected using the Stripe Size box shown in Figure 8. RAID 5 only allows a 64K stripe size. RAID 1 does not allow the user to select the striping size.

Select write cache properties

The Escalade ATA RAID Controller gives you a choice of disabling the write cache for your disk arrays. Write cache is used to store data locally on the drive before it is written to the disk, allowing the computer to continue with its next task. Enabling the write cache

3ware Disk Array Configuration Utility

results in the most efficient access times for your computer system. There may be instances when you always want the computer to wait for the drive to write all the data to disk before going on to its next task. For this case, you must disable the write cache. To disable the write cache, select disable from the array???s Write Cache State selection. The default for Write Cache State is enable.

Confirm array configuration

Select the OK button to confirm creating the array or Cancel to reject it. The array is not actually created and no data will be over- written until you have finished making all your changes and select the F8 key.

Note: The current limitation is 2 TB for any physical or logical unit. If you attempt to create an array over 2 TB the BIOS will display the following message: ???The amount of disk space available exceeds the maxi- mum allowable capacity. The array capacity will be lim- ited to 2 TB.???

For RAID 5 Arrays

Because of the Read-Modify-Write operations, zeros are first writ- ten to all drives in the array before the array is functional. The screen shown in Figure 10 appears after selecting OK to confirm array creation.

If desired, the write-zeros operation can be aborted by rebooting the system. Once booted to the operating system, the array goes into initialization mode after a delay of up to ten minutes. The advan- tage of doing this is that the RAID 5 can be used immediately, although it will not be fault tolerant until the initialization is com- plete. The disadvantage of doing this is that it will take longer for

3ware Escalade ATA RAID Controller Installation Guide

the array to be fully redundant, as it takes longer to initialize an array than it takes to write zeros to the array.

Caution: When running in initializing mode the array is not redundant. You cannot remove any drive.

For RAID 1 or 10 Arrays

RAID 1 and 10 arrays are not profiled when created, or initialized after booting into the OS. When the firmware receives the first ver- ify request, given that the array was never initialized, the initializa- tion will then begin. Any subsequent verify operations will then perform the verification of the array (check data consistency). An AEN will inform the user that the first verify is actually an initial- ization.

Specifying a Hot Spare

The Escalade ATA RAID Controller gives you the option to specify a hot spare from one of your Available Drives. If a hot spare is specified and the array degrades, an event notification will be gen- erated. The hot spare will dynamically replace the failed drive in an array without user intervention. Select a hot spare by navigating to an Available Drive. The Toggle Hot Spare verbiage at the bottom of the screen will be black if the drive can be used as a hot spare. Enter s to select the hot spare or to disable the hot spare if it is already enabled.

3ware Disk Array Configuration Utility

Note: Hot spare drives need to have the same or larger storage capacity than the RAID 1, RAID 5 or RAID 10 drives.

Changing an existing configuration

1Back up any disk arrays that contain data that you want to retain before the configuration change.

2Create new disk arrays following the instructions in the Deter- mining your configuration, Creating a disk array and Delet- ing a disk array sections. You may need to delete existing arrays to free up disks first.

3Boot, partition and format any new disk arrays or free disks.

4When you are finished configuring, restore from backup any data saved from previous disk arrays

Modifying a disk array

To modify an existing array you must first delete it then recreate it with the new drives. As with all disk array operations, there is no way to modify an existing array without overwriting data on the drives involved.

Deleting a disk array

To delete an array (see Figure 11) first select the array by navigat- ing to it and hitting Enter. An asterisk in the left most column indi- cates the array is selected.

3ware Escalade ATA RAID Controller Installation Guide

3ware Disk Array Configuration

Figure 11. Delete Disk Array Display

Navigate to the Delete Array button and hit Enter to bring up the Delete Disk Array display. Check that the correct drives are listed. Select the OK key to confirm deleting the array or Cancel to reject it. Recall that the array is not actually deleted and no data will be overwritten until you have finished making all your changes and selected the F8 key.

How to maintain or verify a disk array

The Maintain Disk Array (see Figure 12) shows the current disk array configuration that you have selected. The array???s Write Cache State can be changed. Refer to Select write cache proper- ties paragraph in the Creating a disk array section. Verify Array can be specified as no or yes. The default is no. Yes launches a fore- ground process that checks the data integrity of a fault tolerant

3ware Disk Array Configuration Utility

array. If the verify array process determines that the mirrored drives are not identical or the parity is not correct, the array is degraded and the rebuild process is launched.

Maintain Disk Array

The array listed below can have its write cache state changed. Verify checks the data integrity of a fault tolerant array.

Figure 12. Maintain Disk Array Display

Note: Fault tolerant arrays can not be verified until after they are initialized. For RAID 1 and 10 arrays the initial verify must first be done in 3DM, otherwise the initialization will not be done.

Rebuilding a mirrored disk array

Escalade ATA RAID Controllers allow you to create fault tolerant disk arrays by selecting a mirrored RAID 1 or RAID 10 array. These disk arrays store identical data on two or more drives to pro- tect against drive failure. If one or more of the drives of a mirrored

3ware Escalade ATA RAID Controller Installation Guide

array is removed, unplugged or fails on read or write requests, the array is marked as DEGRADED and the drive is marked as Not In Use or is not displayed if no longer available. (see Figure 13 and Figure 14).

You can still read and write data from a degraded disk array, but the array will not be fault tolerant until it is rebuilt using the Rebuild feature, described in the 3ware Disk Array Configuration Utility or 3DM Disk Management Utility chapters.

Figure 13. Degraded RAID 1 Array Drive When Not in Use

3ware Disk Array Configuration Utility

3ware Disk Array Configuration

Figure 14. Degraded RAID 10 Array Drive When Not in Use

Note: A RAID 10 array can be configured with either four, six, eight, ten or twelve drives. In a 4-drive config- uration, up to two drives can be rebuilt. In a 6-drive con- figuration, up to three drives can be rebuilt. In an 8-drive configuration, up to four drives can be rebuilt. In a 12- drive configuration, up to six drives can be rebuilt.

Rebuilding a RAID 5 disk array

Escalade ATA RAID Controllers allow you to create fault tolerant RAID 5 disk arrays. These disk arrays achieve fault tolerance by using a simple (exclusive OR) function to generate the parity data

3ware Escalade ATA RAID Controller Installation Guide

that is distributed on all drives. If one of the drives is removed, unplugged or fails on read or write requests, the array is marked as DEGRADED and the drive is marked as Not In Use or is not dis- played if no longer available (see Figure 15). When running in Degraded mode, the missing data is reconstructed from all non- degraded drives.

Figure 15. Degraded RAID 5 Array Drive When Not in Use

As in the case of RAID 1 and 10 arrays RAID 5 arrays allow you to read and write data from a degraded disk array, but the array will not be fault tolerant until it is rebuilt using the Rebuild feature. (Refer to the 3ware Disk Array Configuration Utility or 3DM Disk Management Utility chapters for more information.)

Rebuilding a mirrored or RAID 5 array with no hot spare

1Reboot the system and enter the Disk Array Configuration Utility.

3ware Disk Array Configuration Utility

2If your mirrored or RAID 5 array has a Not in Use member drive, the drive may still be usable. Try rebuilding with the Not in Use drive intact. Simply select the array and then the Rebuild button.

3Confirm that you selected the correct array by hitting OK in the Rebuild confirmation display.

4Select F8 to exit the Disk Array Configuration Utility. The array will begin rebuilding after completion of the operating sys- tem load.

5If the rebuild fails and you have no Available Drives, you must power down the system and replace the failed or Not In Use drive. Power on the system and enter the Disk Array Configu- ration Utility.

6Select an available drive to replace the faulted drive in the array by navigating the cursor over the available drive and hitting Enter (see Figure 16). An asterisk in the left most column indi- cates the drive is selected.

7Navigate to the degraded array and press Enter to select it.

Auto rebuild of a mirrored or RAID 5 array

If a hot spare is specified and the mirrored or RAID 5 array degrades, an event notification is generated and the hot spare dynamically replaces the failed drive in the array without user inter- vention. Rebuild will automatically be launched as a background process and an event notification will notify the user when the rebuild process is complete.

3ware Disk Array Configuration Utility

Auto rebuild on power failure

During driver startup 3ware???s auto rebuild feature sets a flag indi- cating that the driver loaded. Upon an orderly shutdown the flag is rewritten, indicating a clean shutdown. During the next system power cycle the firmware queries the flag. For a RAID 1 or 10 con- figuration, if there was a problem, the firmware degrades the sec- ondary drive in the array and starts the background rebuild of the mirrored drive. When the rebuild is complete the two halves of the mirror are redundant again. For a RAID 5 configuration, if there is a problem, the firmware starts the background verification that checks that the parity matches the data.

Cancelling and restarting a rebuild with a new drive

Currently, a rebuild cannot be cancelled using the 3DM software, but a rebuild can be aborted by physically removing the disk used to replace the degraded drive. Abort a rebuild by following the appli- cable procedure below.

If your system has hot swap carriers:

1Remove the disk while the system is powered. The rebuild will be immediately aborted.

2Go to the Configure screen and click the box in front of the disk drive that was removed. Click on Remove Drive.

3Add another drive and click on the box in front of this port. Click on Add Drive. The drive is called ???RAID Disk???.

4Click the boxes in front of the RAID Disk and the degraded array. Select Rebuild. The rebuild starts with the new disk drive.

If your system does not have hot swap carriers:

1Power down the system and remove the disk drive that caused the array to become degraded.

2Add a different disk drive to rebuild the array.

3Press Alt + F3 at Boot time to enter 3ware BIOS.

4Select the degraded array and the newly added drive.

5Select Rebuild.
