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 two 2.5-inch SAS or SATA 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 SAS 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:
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 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.
NOTICE: To maintain proper system cooling, all empty hard-drive bays must have drive blanks installed.
Installing a Hot-Plug Hard Drive
NOTICE: When installing a hard drive, ensure that the adjacent drives are fully installed. Inserting a hard-drive carrier and attempting to lock its handle next to a partially installed carrier can damage the partially installed carrier's shield spring and make it unusable.
NOTICE: Not all operating systems support hot-plug drive installation. See the documentation supplied with your operating system.
Insert the hard-drive carrier into the drive bay until the carrier
contacts the backplane.
Close the handle to lock the drive in place.
Replace the front bezel, if it was removed in step 1.
Replacing a Hard-Drive Carrier
Two versions of hard-drive carriers are used with your system. The version for SATA hard drives has a single set of (four) mounting holes on the side rails. The second version, called a SAS/SATAu hard-drive carrier, has an extra four mounting holes to enable either a "SAS" and "SATAu" mounting position. When using the SAS/SATAu hard-drive carrier, observe these rules with regard to your system:
Use only SAS hard drives with SAS/SATAu drive carriers.
Use only the "SAS" mounting position on the carrier. (The SATAu position is reserved.)
Figure 3-6 illustrates a SAS hard drive being installed in a SAS/SATAu hard-drive carrier.
Removing a Hard Drive From a Hard-Drive Carrier
Remove the four screws from the slide rails on the hard-drive carrier and separate the hard drive from the carrier.
Installing a Hard Drive Into a Drive Carrier
Insert the hard drive into the hard-drive carrier with the connector end
of the drive at the rear. See Figure 3-6.
Viewing the assembly as shown in Figure 3-6, align the screw holes on
the hard drive with the rear set of holes on the hard drive carrier.
When aligned correctly, the rear of the hard drive will be flush with the rear of the hard-drive carrier.
Attach the four screws to secure the hard drive to the hard-drive carrier.
See Figure 3-6.

Power Supplies
Your system supports one or two power supplies rated at an output of 700 W. If only one power supply is installed, it must be installed in the left power supply bay (PS1). If two power supplies are installed, the second power supply provides hot-pluggable power redundancy. In redundant mode, the system distributes the power load across both power supplies to maximize efficiency. When a power supply is removed with the system powered on, the full power load is picked up by the remaining power supply.
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 to operate the system normally. On power-redundant systems, remove and replace only one power supply at a time in a system that is powered on.
NOTE: On your rack system, you may have to unlatch and lift the optional 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.

System Memory
You can upgrade your system memory to a maximum of 128 GB by installing 667-MHz registered parity DDR2 memory modules (DIMMs) in sets of 512-MB, 1-GB, 2-GB, 4-GB, or 8-GB single- or dual-ranked modules (quad-ranked modules are not supported). The memory sockets are located on the system board under the memory module cooling shrouds and are split into two separate groups of eight sockets each. Each eight-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 four, eight, or sixteen DIMMs. The minimum configuration is four 512-MB DIMMs.
DIMMs must be installed in matched sets of identical speed, technology, and size in the following sockets:
A1, A2, B1, and B2 — four identical DIMMs in this set
A3, A4, B3, and B4 — four identical DIMMs in this set
A5 through A8 and B5 through B8 — eight identical DIMMs in this set
Minimum configurations (four DIMMs) must occupy sockets A1, A2, B1, and B2.
A matched DIMM set can be mixed with another matched DIMM set of the next smaller size. For example, a DIMM set containing 2-GB DIMMs can be mixed with another DIMM set containing 1-GB DIMMs, but not a set containing 512-MB DIMMs. The larger capacity DIMMs must occupy the lower-numbered DIMM sockets.
Table 3-1 shows the available memory configurations following these guidelines.

Memory Sparing Support
Memory sparing is supported in 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.
NOTE: The Memory sparing and node interleaving features cannot be used at the same time. To use memory sparing, you must disable the Node Interleaving option in the System Setup program.
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.
