DIMM Configuration
The memory subsystem supports only Double Data Rate Synchronous Dynamic Random Access Memory
(DDR SDRAM) technology utilizing industry-standard PC2100 type DDR SDRAM DIMMs, 1.2-inches tall,
using a 184-pin JEDEC standard connector.
In the server blade, you must load the DIMMs in pairs. To enable chip sparing, you must four DIMMs of the
same capacity and configuration. Table 4-1 summarizes the server blade memory solutions.
NOTE Loading DIMMs as a quad (four identical DIMMs) enables lock-step mode and chip sparing.
