Memory options
This server supports up to four memory boards. Each memory board contains six DIMM slots for a total of
24 DIMM slots in the server. Memory can be expanded by installing PC2-3200R Registered DDR2 DRAM
DIMMs.
The server supports a host of AMP options to optimize server availability:
•
Advanced ECC (hot-add enabled) (" Advanced ECC Memory " on page 61 )
•
Advanced ECC (hot-add disabled) (" Advanced ECC Memory " on page 61 )
•
Online Spare Memory (on page 62 )
•
Hot-Plug Mirrored Memory (dual- and quad-board) (" Hot-plug mirrored memory " on page 63 )
•
Hot-Plug RAID Memory (on page 64 )
Hot-plug operations can be hot-add or hot-replace. Hot-add makes additional memory resources available
to the OS. Hot-replace allows failed or degraded DIMMs to be replaced while the server is running.
The maximum supported memory per memory board is 16 GB using four 4-GB dual-rank DIMMs.
Although six DIMM slots exist per board, the system architecture allows a maximum of only four dual-rank
DIMMs per memory board to optimize performance.
For an overview of single- and dual-rank DIMMs, refer to "Single- and Dual-Rank DIMMs (on page 61 )."
For DIMM slot locations and bank assignments, refer to "DIMM Slots (" DIMM slot locations " on page
23 )."
General memory configuration requirements
The following configuration requirements apply regardless of the AMP mode.
•
DIMMs must be installed in pairs.
•
DIMM pairs in a memory bank must contain DIMMs with the same part number.
•
Always populate the memory boards in sequential order: Board 1, Board 2, Board 3, and Board 4.
Any deviation from this requirement results in the server booting in Advanced ECC mode and
Advanced ECC guidelines apply.
•
Always populate the DIMMs in sequential order per bank: Bank A, Bank B, and Bank C.
•
Dual-rank DIMMs (" Single- and Dual-rank DIMMs " on page 61 ) must be populated before single-
rank DIMMs (see table).
•
If dual-rank DIMMs are installed in Bank A and Bank B, no additional DIMMs may be installed in
Bank C.
•
The following table lists all seven valid combinations of single- and dual-rank DIMM configurations
for a memory board. "Single" indicates a bank of single-rank DIMMs. "Dual" indicates a bank of
dual-rank DIMMs.
NOTE: A bank contains two DIMMs.
