Using USB Diskette Or USB DVD/CD Drives

The server module has USB ports on the front which allow you to connect a USB diskette drive, USB flash drive, USB

DVD/CD drive, keyboard, or mouse. The USB drives can be used to configure the server module.

NOTE: Your server module supports only Dell-branded USB 2.0 drives. Use the optional external drive storage tray

to support the drive while in use.

NOTE: If the drive must be designated as the boot drive, connect the USB drive, restart the system, then enter the

System Setup and set the drive as first in the boot sequence. The USB device is displayed in the boot order setup

screen only if it is attached to the system before you run the System Setup. You can also select the boot device by

pressing <F11> during system start-up and selecting a boot device for the current boot sequence.

Hard-Drive Features

Your system supports two 2.5 inch SSD, SAS or SATA hard drives.

NOTE: SSD/SAS/SATA hard drives cannot be mixed within a server module.

The hard-disk drives plug into the hard-drive backplane inside the server module. On server modules with a diskless

configuration, all hard drive slots must be filled with hard-drive blanks, and the hard-drive backplane must still be

installed to maintain proper airflow.

The hard-drive indicators display different patterns as drive events occur in the system.

NOTE: The server module must have a hard drive or a hard-drive blank installed in each hard-drive bay.

System Memory

Your system supports DDR3 unbuffered ECC DIMMs (UDIMM ECC) and registered DIMMs (RDIMMs). It supports DDR3

and DDR3L voltage specifications.

NOTE: MT/s indicates DIMM speed in MegaTransfers per second.

Memory bus operating frequency can be 1600 MT/s, 1333 MT/s, 1066 MT/s, or 800 MT/s depending on:

• DIMM type (UDIMM, RDIMM, or LRDIMM)

• DIMM configuration (number of ranks)

• maximum frequency of the DIMMs

• number of DIMMs populated per channel

• DIMM operating voltage

• system profile selected (for example, Performance Optimized, Custom, or Dense Configuration Optimized)

• maximum supported DIMM frequency of the processors

The system contains 24 memory sockets split into two sets of 12 sockets, one set per processor. Each 12-socket set is

organized into four channels. In each channel, the release levers of the first socket are marked white, the second socket

black, and the third socket green.

NOTE: DIMMs in sockets A1 to A12 are assigned to processor 1 and DIMMs in sockets B1 to B12 are assigned to

processor 2.

The following table shows the memory populations and operating frequencies for the supported configurations.

General Memory Module Installation Guidelines

NOTE: Memory configurations that fail to observe these guidelines can prevent your system from starting and

producing any video output, hanging during memory configuration, or operating with reduced memory.

This system supports Flexible Memory Configuration, enabling the system to be configured and run in any valid chipset

architectural configuration. The following are the recommended guidelines for best performance:

• UDIMMs, RDIMMs, and LRDIMMs must not be mixed.

• x4 and x8 DRAM based DIMMs can be mixed. For more information, see Mode-Specific Guidelines.

• A maximum of two UDIMMs can be populated in a channel.

• Up to three LRDIMMs can be populated regardless of rank count.

• Up to two quad-rank RDIMMs and up to three dual- or single-rank RDIMMs can be populated per channel.

When a quad-rank RDIMM is populated in the first slot with white release levers, the third DIMM slot in the

channel with green release levers cannot be populated.

• Populate DIMM sockets only if a processor is installed. For single-processor systems, sockets A1 to A12 are

available. For dual-processor systems, sockets A1 to A12 and sockets B1 to B12 are available.

• Populate all sockets with white release tabs first, then black, and then green.

• Do not populate the third DIMM socket in a channel with green release tabs, if a quad-rank RDIMM is populated

in the first socket with white release tabs.

• Populate the sockets by highest rank count in the following order - first in sockets with white release levers,

then black, and then green. For example, if you want to mix quad-rank and dual-rank DIMMs, populate quad-

rank DIMMs in the sockets with white release tabs and dual-rank DIMMs in the sockets with black release tabs.

• In a dual-processor configuration, the memory configuration for each processor must be identical. For example,

if you populate socket A1 for processor 1, then populate socket B1 for processor 2, and so on.

• Memory modules of different sizes can be mixed provided that other memory population rules are followed (for

example, 2 GB and 4 GB memory modules can be mixed).

• Populate four DIMMs per processor (one DIMM per channel) at a time to maximize performance.

• If memory modules with different speeds are installed, they will operate at the speed of the slowest installed

memory module(s) or slower depending on system DIMM configuration.

• Populate DIMMs based on the following processor— heat sink configurations.

channels 0 and 3 and two

DIMMs in channels 1 and 2)

NOTE: For optimal performance, your system may be configured with a larger heat sink than listed above.

Do not use any heat sink smaller than the configurations described above.

Mode-Specific Guidelines

Four memory channels are allocated to each processor. The allowable configurations depend on the memory mode

selected.

NOTE: x4 and x8 DRAM based DIMMs can be mixed providing support for RAS features. However, all guidelines for

specific RAS features must be followed. x4 DRAM based DIMMs retain Single Device Data Correction (SDDC) in

memory optimized (independent channel) mode. x8 DRAM based DIMMs require Advanced ECC mode to gain

SDDC.

The following sections provide additional slot population guidelines for each mode.

Advanced ECC (Lockstep)

Advanced ECC mode extends SDDC from x4 DRAM based DIMMs to both x4 and x8 DRAMs. This protects against single

DRAM chip failures during normal operation.

Memory installation guidelines:

• Memory modules must be identical in size, speed, and technology.

• DIMMs installed in memory sockets with white release tabs must be identical and similar rule applies for

sockets with black and green release tabs. This ensures that identical DIMMs are installed in matched pairs -

for example, A1 with A2, A3 with A4, A5 with A6, and so on.

NOTE: Advanced ECC with mirroring is not supported.

Memory Optimized (Independent Channel) Mode

This mode supports SDDC only for memory modules that use x4 device width and does not impose any specific slot

population requirements.

Memory Sparing

NOTE: To use memory sparing, this feature must be enabled in the System Setup.

In this mode, one rank per channel is reserved as a spare. If persistent correctable errors are detected on a rank, the

data from this rank is copied to the spare rank and the failed rank is disabled.

With memory sparing enabled, the system memory available to the operating system is reduced by one rank per

channel. For example, in a dual-processor configuration with sixteen 4 GB dual-rank DIMMs, the available system

memory is: 3/4 (ranks/channel) × 16 (DIMMs) × 4 GB = 48 GB, and not 16 (DIMMs) × 4 GB = 64 GB.

NOTE: Memory sparing does not offer protection against a multi-bit uncorrectable error.

NOTE: Both Advanced ECC/Lockstep and Optimizer modes support Memory Sparing.

Memory Mirroring

Memory Mirroring offers the strongest DIMM reliability mode compared to all other modes, providing improved

uncorrectable multi-bit failure protection. In a mirrored configuration, the total available system memory is one half of

the total installed physical memory. Half of the installed memory is used to mirror the active DIMMs. In the event of an

uncorrectable error, the system will switch over to the mirrored copy. This ensures SDDC and multi-bit protection.

Memory installation guidelines:

• Memory modules must be identical in size, speed, and technology.

• DIMMs installed in memory sockets with white release tabs must be identical and similar rule applies for

sockets with black and green release tabs. This ensures that identical DIMMs are installed in matched pairs -

for example, A1 with A2, A3 with A4, A5 with A6, and so on.

Sample Memory Configurations

The following tables show sample memory configurations that follow the appropriate memory guidelines stated in this

section.

NOTE: 16 GB quad-rank RDIMMs are not supported.

NOTE: 1R, 2R, and 4R in the following tables indicate single-, dual-, and quad-rank DIMMs respectively.

Removing Memory Modules

WARNING: The DIMMs are hot to touch for some time after the server module has been powered down. Allow

time for the DIMMs to cool before handling them. Handle the DIMMs by the card edges and avoid touching the

DIMM components.

CAUTION: Many repairs may only be done by a certified service technician. You should only perform

troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or

telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your

warranty. Read and follow the safety instructions that came with the product.

CAUTION: To ensure proper system cooling, memory-module blanks must be installed in any memory socket that is

not occupied. Remove memory-module blanks only if you intend to install memory in those sockets.

CAUTION: If you are permanently removing a processor, you must install a socket protective cap and a processor/

DIMM blank in the vacant socket to ensure proper system cooling. The processor/DIMM blank covers the vacant

sockets for the DIMMs and the processor.

1. Remove the server module from the enclosure.

2. Open the server module.

3. Remove the cooling shroud.

4. Locate the memory module socket(s).

CAUTION: Handle each memory module only on either card edge, making sure not to touch the middle of the

memory module.

5. Press down and out on the ejectors on each end of the socket until the memory module pops out of the socket.

6. Install the cooling shroud.

7. Close the server module.
