#4494 16 GB Main Storage 570
#4494 - 16 GB Main Storage (ships four 4 GB DIMMs for a total of 16 GB) Must be installed on a processor card by itself or with another #4494 or with features #4492 or #7049. The #4494 16 GB DDR1 Main Storage consists of four 4 GB DDR1 DIMMs for a total of 16 GB of main storage. The #4494 must be installed on a processor card either by itself (other four DIMM slots empty), with another #4494, or with features #4492 or #7049. Four available memory DIMM slots are required. Minimum operating system level: i5/OS V5R3.
The Model 570 offers pluggable DIMMs for memory. Each 0/2-way processor card contains eight slots for up to eight pluggable DIMMs. The minimum memory for a for a Model 570 is 2 GB. The maximum memory capacity depends upon the number of processors ordered for the system and on the type of memory and functionality required.
The rules for mixing and matching DIMMs are:
- Install memory DIMMs in quads.
- Quads must be the same DIMM.
- Memory balancing and spreading is required.
For the #0931 1/2-way server, DIMMs are installed in the following sequence:
- The first quad of DIMMs is plugged into DIMM slots J0A, J0C, J1A, and J1C.
- The second quad of DIMMs is plugged into DIMM slots J0B, J0D, J1B, and J1D.
