General DIMM slot population guidelines
• The server has four memory slots.
• The server supports two channels with two UDIMM slots per channel.
• Memory channel A consists of the two UDIMMs that are closest to the processor.
• Memory channel B consists of the two UDIMMs that are located farthest from the processor.
• Different types of processors have different types of memory support.
• The server supports dual-rank, 1,333 MT/s ECC UDIMMs.
• The server supports up to 16 GB (4x4-GB) for UDIMMs.
• The server does not support:
o LV-DIMMs
o RDIMMs
o Non-ECC UDIMMs
• When installing DIMMs:
o If the processor is not installed, then do not install DIMMs.
o Populate DIMMs from heaviest load (double-rank) to lightest load (single-rank).
o Use HP-qualified UDIMMs.
o The DIMM farthest from the processor (either CHA or CHB) must be populated first.
SAS and SATA hard drive options
The server provides non-hot-plug capability through an embedded SATA controller. To obtain hot-plug
capability, install an optional controller and hot-plug cable option kit. The server supports up to four
non-hot-plug or hot-plug LFF hard drives and up to eight hot-plug SFF hard drives.
Hard drive guidelines
When adding hard drives to the server, observe the following general guidelines:
• The system automatically sets all drive numbers.
• If only one hard drive is used, install it in the bay with the lowest drive number.
• Drives must be the same capacity to provide the greatest storage space efficiency when drives are
grouped together into the same drive array.
Optional storage controllers provide support for hot-plug capability and drive LEDs. Controller options are:
• The embedded controller supports non-hot-plug SATA hard drives. Drive LEDs are not supported.
• Optional SATA controllers support hot-plug SATA hard drives and drive LEDs.
• Optional SAS controllers support hot-plug SAS or SATA hard drives and drive LEDs.
