Hard Drives

This subsection describes how to install and configure SAS or SATA hard drives in the system's internal hard-drive bays. Your system features up to eight 2.5-inch hard drives. All drives connect to the system board through the SAS/SATA backplane board. See Figure 6-3. Hard drives are supplied in special hot-pluggable drive carriers that fit in the hard-drive bays.

NOTICE: Before attempting to remove or install a drive while the system is running, see the documentation for the optional SAS RAID controller daughter card to ensure that the host adapter is configured correctly to support hot-plug drive removal and insertion.

NOTE: All installed drives must be either SAS or SATA. Mixed drive configurations are not supported.

NOTE: It is recommended that you use only drives that have been tested and approved for use with the SAS/SATA backplane board.

You may need to use different programs than those provided with the operating system to partition and format SAS or SATA hard drives.

NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive failure.

When you format a hard drive, allow enough time for the formatting to be completed. Be aware that high-capacity hard drives can take a number of hours to format.

Removing a Drive Blank

NOTICE: To maintain proper system cooling, all empty hard-drive bays must have drive blanks installed. If you remove a hard-drive carrier from the system and do not reinstall it, you must replace the carrier with a drive blank.

Remove the drive blank as you would the 2.5-inch hard drive carrier:

Remove the front bezel, if attached. See Removing the Front Bezel.
Open the drive blank release handle to release the blank. See Figure 3-5.
Slide the drive blank out until it is free of the drive bay.

Installing a Drive Blank

Install the hard drive blank as you would a 2.5-inch hard drive carrier:

Remove the front bezel, if attached. See Removing the Front Bezel.
Open the handle on the drive blank.
Insert the drive blank into the drive bay until the blank is fully seated.
Close the handle to lock the blank in place.
Replace the front bezel, if it was removed in step 1.

Removing a Hot-Plug Hard Drive

Remove the front bezel, if attached. See Removing the Front Bezel.
From the RAID management software, prepare the drive for removal and wait until the hard-drive indicators on the drive carrier signal that the drive can be removed safely. See your SAS RAID controller documentation for information about hot-plug drive removal.

If the drive has been online, the green activity/fault indicator will flash as the drive is powered down. When both drive indicators are off, the drive is ready for removal.

Open the drive carrier release handle to release the drive. See Figure 3-5.
Slide the hard drive out until it is free of the drive bay.
If you do not replace the hard drive, insert a drive blank in the vacated drive bay. See Installing a Drive Blank.

Power Supplies

Your system supports one or two power supplies rated at an output of 750 W. If only one power supply is installed, it must be installed in the left power supply bay (1). If two power supplies are installed, the second power supply serves as a redundant, hot-plug power source.

NOTICE: To ensure proper system cooling, the power supply blank must be installed on the unoccupied power supply bay in a non-redundant configuration. See Installing the Power Supply Blank.

Removing a Power Supply

NOTICE: The system requires one power supply for the system to operate normally. The system is in the redundant mode when two power supplies are installed and both power supplies are connected to an AC power source. Remove and replace only one power supply at a time in a system that is powered on. Operating the system with only one power supply installed and without a power supply blank installed for extended periods of time can cause the system to overheat.

NOTICE: If only one power supply is installed, it must be installed in the left power supply bay (1).

NOTICE: If you connect the system to a power source in the range of 120 to 220 VAC, and if two power supplies are installed, the second power supply serves as a redundant, hot-plug power source.

NOTE: On your rack system, you may have to unlatch and lift the cable management arm if it interferes with power supply removal. For information about the cable management arm, see the system's Rack Installation Guide.

If your system has a single power supply, turn off the system and all attached peripherals. For a redundant system, you can leave the system running and proceed to the next step.
Disconnect the power cable from the power source.
Disconnect the power cable from the power supply and remove the cable from the cable retention bracket.
Release the locking tab on the left side of the power supply by pressing in toward the right, and rotate the power-supply handle up until the power supply is released from the chassis. See Figure 3-7.

SAS Controller Daughter Card

Your system includes a dedicated slot on the sideplane for a SAS controller daughter card. The SAS controller provides the SAS storage subsystem for your system's internal hard drives supporting either SAS or SATA hard drives. Both RAID and non-RAID versions of the controller are available for your system.

The non-RAID SAS controller supports up to four SAS or SATA internal hard drives. All hard drives must be either SAS or SATA (mixed SAS/SATA drive configurations are not supported) and the drives must occupy the active drive bays, 0 through 3.

The optional SAS RAID controller supports up to eight SAS or SATA internal hard drives and allows you to set up the drives in a RAID configuration. All hard drives in the configuration must be either SAS or SATA and all drive bays are active. See the RAID user documentation for information on the available RAID configurations and for instructions on how to set up a RAID.

Although the cabling for the two types of daughter cards is different (the SAS controller daughter card has only one connector, while the SAS RAID controller daughter card has two), both cards install into the sideplane as described below. The RAID version of the SAS controller daughter card is shown in Figure 3-9.

Installing a SAS Controller Daughter Card

NOTICE: When installing a SAS RAID controller, do not press on the RAID card DIMM while installing the RAID card into the sideplane board.

NOTE: If you are installing a replacement RAID card, do not remove the plastic cover protecting the card until after installation of the card is complete.

System Memory

You can upgrade your system memory to a maximum of 32 GB (for a one-processor configuration) or 64 GB (for a two-processor configuration) by installing 667-MHz registered parity DDR-II memory modules (DIMMs) in sets of 512-MB, 1-GB, 2-GB, 4-GB, or 8-GB (when available) modules. The memory sockets are located on the system board under the cooling shroud and are split into two separate groups of four sockets each. Each four-socket group is adjacent to its respective processor.

Your system hardware supports Non-Uniform Memory Architecture (NUMA). Each processor has its own memory controller and local memory for reduced access times, but it can also access memory from another processor. This architecture improves system performance if an operating system is installed that supports this feature.

NOTICE: To enable NUMA, run the System Setup program and disable the Node Interleaving option. See Using the System Setup Program.

General Memory Module Installation Guidelines

To ensure optimal performance of your system, observe the following guidelines when configuring your system memory.

Memory must be installed in configurations of two, four, or eight DIMMs. The minimum configuration for a two-processor system is four DIMMs.
DIMMs must be installed in matched pairs of identical speed, technology, and size in the following pairs of sockets:

DIMM 1 and DIMM 2
DIMM 3 and DIMM 4
DIMM 5 and DIMM 6
DIMM 7 and DIMM 8

Minimum configurations must occupy the lower-numbered sockets (DIMM 1 and DIMM 2 for a one-processor configuration and also DIMM5 and DIMM6 for a two-processor configuration).
Within a DIMM group, a pair of DIMMs of one size can be mixed with a pair of DIMMs of a different size (N+3, or up to three DIMM sizes larger). Larger capacity DIMMs must occupy the lower-numbered sockets.

Table 3-1 shows the available memory configurations following these guidelines.

Table 3-1. Memory Configurations

Total System Memory		DIMM Socket
Single-Processor System	Dual-Processor System	DIMM 1 / DIMM 5	DIMM 2/ DIMM 6	DIMM 3/ DIMM 7	DIMM 4/ DIMM 8

Memory Sparing Support

Memory sparing is supported in single- or dual-processor systems that have one of the fully populated memory configurations shown in Table 3-1. The memory sparing feature must be enabled in the Memory Information screen of the System Setup program. See Using the System Setup Program. To use memory sparing, you must disable node interleaving.

Memory sparing is applied independently to the two groups of DIMMs on opposite sides of the processor sockets. To support memory sparing, all DIMM sockets within a DIMM group must be populated.

When enabled, memory sparing allocates and reserves ranks of memory from the installed DIMMs to act as spare memory in the event of a memory channel failure. A memory channel uses paired DIMMs; for memory sparing to work, DIMMs must be paired as spares also.

Memory sparing allocates only the first rank of memory of a DIMM. For a single-rank DIMM, the entire capacity of the DIMM must be allocated for sparing along with the adjacent single-rank DIMM to spare a memory channel. For dual-rank DIMMs, two DIMMs are also required for sparing, but as only the first rank of each DIMM is allocated, only half of a dual-rank DIMM's capacity is allocated for sparing. The second ranks on both DIMMs are available memory.

Memory sparing calculates the appropriate DIMMs to spare by searching the DIMM sockets, starting with the higher-numbered socket pair (specifically, sockets 3 and 4 or sockets 7 and 8), for an amount of memory large enough to spare one of the available channels of memory. If the DIMMs in these sockets are sufficient to spare a channel of the available memory, the first rank of each of those two DIMMs are spared. If the amount of memory is not large enough to spare an available memory channel, the system spares the DIMM ranks in the lower-numbered sockets. Table 3-2 shows how memory sparing works in various memory configurations.

Table 3-2. Memory Sparing in Single- and Dual-Processor Configurations

Processor 1				Processor 2				Available Memory	Spared Memory
