GS Options
Step 4 - Select Memory Options - Mandatory
Configuration Guidelines
1.
Mandatory selection of one memory option per CPU (two memory options per Dual CPU Building Block Module).
2.
Optional selection of a second memory option for each CPU.
3. Both options must be the same size and speed for a CPU, but different size options can be used on different CPUs.
4. Each memory option consists of four RDRAM Inline Memory Modules (RIMMs). An optional fifth RIMM (RAID option)
may be selected for redundancy that will allow uninterrupted operation in case of the loss of an entire RIMM. RAID
options must be selected and matched for each memory option on one CPU, but RAID options do not have to be
selected for all CPUs.
NOTE: Memory must be ordered for iCAP CPU Modules as well as Full Use CPU Modules. The system will use memory
installed on the iCAP CPU Module even when the iCAP CPU is inactive.
Memory Application Examples
The following examples illustrate different ways of configuring one 8P System Building Block Drawer with eight CPUs and a
total of 16 GB of memory.
