HyperTransport??? and Dual-Core Technology

HyperTransport technology can increase overall computer performance by removing I/O bottlenecks, increasing system bandwidth, and reducing system latency. A fully integrated DDR memory controller allows a direct connection between the processor and the main memory. Dual-Core is a technology in which two physical computational units exist inside a single processor package, thereby increasing computing efficiency and multi-tasking ability.

While many programs can benefit from HyperTransport and dual-core technology, some programs may have not been optimized for them and may require an update from the software manufacturer. Contact the software manufacturer for updates and information about using HyperTransport or dual-core technology with your software. To determine if your computer is using HyperTransport technology, check the system setup option for HyperTransport under the Performance tab (see System Setup).

Power Management

Your computer can be set to use less power when you are not working. You control the power usage through the operating system installed on your computer and certain option settings in system setup. These periods of reduced power are called "sleep modes."

NOTE: All components installed in the computer must support the hibernate and/or standby mode feature(s) and have the appropriate drivers loaded to enter either of these sleep modes. For more information, see the manufacturer's documentation for each component.

???Standby. In this sleep mode, power is reduced or turned off for most components, including the cooling fans. However, system memory remains active.

???Hibernate. This sleep mode reduces power consumption to a minimum by writing all data in system memory to a hard drive and then removing system power. Waking up from this mode restarts the computer, and the memory contents are restored. Operation then resumes where the computer left off when it entered the hibernation mode.

???Shutdown. This sleep mode removes all power from the computer except a small auxiliary amount. As long as the computer remains connected to an electrical outlet, it can be automatically or remotely started. For example, the Auto Power On option in system setup allows the computer to automatically start at a specified time. Also, your network administrator can remotely start your computer using a power management event such as Remote Wake Up.

The following table lists the sleep modes and the methods you can use to wake the computer from each mode.

Sleep Mode Wake-Up Methods (Windows XP)

NOTE: For more information on power management, see your operating system documentation.

About RAID Configurations

NOTICE: In order to use the migrating option to convert a RAID configuration without losing data, your hard drive must initially be set up as a single drive RAID 0 array before the operating system is loaded onto the drive (see Using the NVIDIA MediaShield ROM Utility for instructions).

This section provides an overview of the RAID configuration that you may have selected when you purchased your computer. A number of RAID configurations are available in the computer industry for different types of uses. The Dell mini tower and desktop models of your OptiPlex computer support RAID level 0 and RAID level 1. (RAID support is not available for the small form factor model.) A RAID level 0 configuration is recommended for high-performance programs, while RAID level 1 is recommended for users that desire a high level of data integrity.

NOTE: RAID levels do not represent a hierarchy. A RAID level 1 configuration is not inherently better or worse than a RAID level 0 configuration.

The NVIDIA RAID controller on your computer can only create a RAID level configuration using two physical drives. The drives should be the same size to ensure that the larger drive does not contain unallocated (and therefore unusable) space.

NOTE: If you purchased your Dell computer with RAID, your computer has been configured with two hard drives that are the same size.

Verifying That RAID Is Working

Your computer displays information pertaining to your RAID configuration at start-up, before loading the operating system. If RAID is not configured, the message none defined appears under RAID Volumes, followed by a list of the physical drives installed in your computer. If a RAID volume is identified, you can then check the Status field to determine the current state of your RAID configuration. The Status field contains information about the following conditions:

???Normal ??? Your RAID configuration is functioning properly.

???Degraded ??? One of your hard drives has failed. The computer is still bootable; however, RAID is not functioning and data is not being copied to the other drive.

???Rebuild ??? Following a degraded condition, the computer has detected the replacement/connection of a secondary hard drive and will automatically restore the RAID configuration the next time the operating system loads.

RAID Level 0 Configuration

NOTICE: Because a RAID level 0 configuration provides no data redundancy, a failure of one drive results in the loss of all data. To protect your data when using a RAID level 0 configuration, perform regular backups.

RAID level 0 uses a storage technique known as data striping to provide a high data-access rate. Data striping is a method of writing consecutive segments, or stripes, of data sequentially across the physical drive(s) to create a large virtual drive. Data striping allows one of the drives to read data while the other drive is searching for and reading the next block.

Another advantage of a RAID level 0 configuration is that it utilizes the full storage capacities of the drives. For example, two 120-GB hard drives combine to provide 240 GB of hard drive space on which to store data.

NOTE: In a RAID level 0 configuration, the size of the configuration is equal to the size of the smallest drive multiplied by the number of drives in the configuration.

RAID Level 1 Configuration

RAID level 1 uses a data-redundancy storage technique known as mirroring to enhance data integrity. When data is written to the primary drive, the data is also duplicated, or mirrored, on the second drive in the configuration. A RAID level 1 configuration sacrifices high data-access rates for its data redundancy advantages.

If a drive failure occurs, subsequent read and write operations are directed to the surviving drive. A replacement drive can then be rebuilt using the data from the surviving drive.

NOTE: In a RAID level 1 configuration, the size of the configuration is equal to the size of the smallest drive in the configuration.

Configuring Your Hard Drives for RAID

Your computer can be configured for RAID, even if you did not select a RAID configuration when the computer was purchased. For an explanation of RAID levels and their requirements, see About RAID Configurations. For information on how to install a hard drive, see Installing a Hard Drive for your mini tower computer or Installing a Hard Drive for your desktop computer.

You can use one of two methods to configure RAID hard drive volumes. The first method uses the NVIDIA MediaShield ROM utility and is performed before you install the operating system onto the hard drive. The second method uses NVIDIA MediaShield and is performed after you have installed the operating system and NVIDIA RAID drivers.Both methods require that you set your computer to RAID-enabled mode before you begin.

Setting Your Computer to RAID-Enabled Mode

Converting From One RAID Configuration to Another RAID Configuration

NVIDIA MediaShield utilizes a one-step process known as migrating to change the current state of a disk or array without losing any data. If needed, additional hard drives can be added to an existing array, including a single-drive RAID 0 configuration for conversion to a two-drive RAID 0 configuration; however, the capacity of the resulting array must be equal to or greater than the size of the original configuration.

RAID 1 to RAID 1 conversions cannot be performed using the migrating process.

NOTICE: Additional hard drives to be used in the (migrated) array must be no smaller than any of the drives in the current configuration.

NOTE: Ensure that all drives to be used in the RAID configuration are RAID-enabled (see Setting Your Computer to RAID-Enabled Mode.)

1.Launch NVIDIA MediaShield.

2.Click to select the array you want to convert.

3.Click Convert Array in the System Tasks pane.

The NVIDIA Convert Array Wizard appears.

4.Click Next.

5.Under RAID Mode Selection, select Mirroring or Striping from the drop-down menu.

6.Click Next.

NOTICE: You will lose all data on the selected drives in the next step.

7.Under Free Disk Selection, select the hard drive(s) you want to include in the (migrated) array by clicking the checkbox beside it.

8.Click Finish.

The MediaShield RAID management utility window appears and displays the status of the upgrade/migration process along with any other installed hard drives.

NOTE: The time it takes to convert an array depends on several factors, such as the speed of the processor, the type and size of the hard drive being used, the operating system, and so on.

Rebuilding a RAID Configuration

If one of the hard drives in a RAID array fails, you can rebuild the array by restoring the data to a replacement drive.

NOTE: Rebuilding an array can be performed only on RAID 1 configurations.

1.Launch NVIDIA MediaShield.

2.Click to select your RAID configuration (Mirroring) in the management utility window.

3.Select Rebuild Array in the System Tasks pane.

The NVIDIA Rebuild Array Wizard appears.

If the DDR2 memory modules are not installed with the same amount of memory in each channel, the computer will continue to operate, but with a slight reduction in performance. See the label in the upper-right corner of the module to determine the module's capacity.

NOTICE: Do not install ECC memory modules. Doing so may cause the system not to boot or otherwise impact performance.

NOTE: Always install DDR2 memory modules in the order indicated on the system board.

The recommended memory configurations are:

??? A pair of matched memory modules installed in connectors DIMM1 and DIMM2

???A memory module installed in connector DIMM1

???A pair of matched memory modules installed in connectors DIMM1 and DIMM2 and another matched pair installed in connectors DIMM3 and DIMM4

Be sure to install a single memory module in DIMM1, the connector closest to the edge of the system board, before you install modules in the other connectors.

Addressing Memory With 4-GB or Greater Configurations (32-bit Operating Systems Only)

This computer supports a maximum of 8 GB of memory. Current 32-bit operating systems, such as Microsoft?? Windows?? XP, can use a maximum of 4 GB of address space; however, the amount of memory available to the operating system is less than that installed. Certain components within the computer require address space in the 4-GB range. Any address space reserved for these components cannot be used by computer memory.

The following components require memory address space:

???System ROM

???APIC(s)

???Integrated PCI devices, such as network connectors and SCSI controllers

???PCI cards

???Graphics card(s)

???PCI Express cards (if applicable)

At start-up, the BIOS identifies the components that require address space. The BIOS dynamically calculates the amount of reserved address space required. The BIOS then subtracts the reserved address space from 4 GB to determine the amount of usable space.

???If the total installed computer memory is less than the usable address space, all installed computer memory is available for use only by the operating system.

???If the total installed computer memory is equal to or greater than the usable address space, a portion of installed memory is not available for use by the operating system.

Removing Memory

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

NOTICE: If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that you may have, even if you purchased the new modules from Dell. If possible, do not pair an original memory module with a new memory module. Otherwise, your computer may not start properly.

You should install your original memory modules in pairs either in connectors DIMM1 and DIMM2 or connectors DIMM3 and DIMM4.

NOTICE: Removing memory modules from DIMM3 and DIMM4 on the desktop computer requires you to remove the optical drive (see Optical Drive). Failure to do so may cause damage to the memory module and the DIMM socket.
