<p>#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.<br /></p><p>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.<br /><br />The rules for mixing and matching DIMMs are:<br /></p> <ul><li>Install memory DIMMs in quads.</li><li>Quads must be the same DIMM.</li><li>Memory balancing and spreading is required.</li></ul> <p>For the #0931 1/2-way server, DIMMs are installed in the following sequence:<br /></p> <ul><li>The first quad of DIMMs is plugged into DIMM slots J0A, J0C, J1A, and J1C.</li><li>The second quad of DIMMs is plugged into DIMM slots J0B, J0D, J1B, and J1D.<br /></li></ul> <p>For the #0921 2/4-way server, DIMMs are installed in the following sequence:<br /></p> <ul><li>Enclosure 1, Processor Card 1: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 1, Processor Card 2: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 1, Processor Card 2: Slots J0B, J0D, J1B, and J1D</li><li>Enclosure 1, Processor Card 1: Slots J0B, J0D, J1B, and J1D</li></ul> <p>For the #0923 5/8-way server, DIMMs are installed in the following sequence:<br /></p> <ul><li>Enclosure 1, Processor Card 1: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 1, Processor Card 2: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 2, Processor Card 3: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 2, Processor Card 4: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 2, Processor Card 4: Slots J0B, J0D, J1B, and J1D</li><li>Enclosure 2, Processor Card 3: Slots J0B, J0D, J1B, and J1D</li><li>Enclosure 1, Processor Card 2: Slots J0B, J0D, J1B, and J1D</li><li>Enclosure 1, Processor Card 1: Slots J0B, J0D, J1B, and J1D</li></ul> <p>For the #0925 9/12-way server, DIMMs are installed in the following sequence:<br /></p> <ul><li>Enclosure 1, Processor Card 1: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 1, Processor Card 2: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 2, Processor Card 3: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 2, Processor Card 4: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 3, Processor Card 5: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 3, Processor Card 6: Slots J0A, J0C, J1A, and J1C</li><li>Enclosure 3, Processor Card 6: Slots J0B, J0D, J1B, and J1D</li><li>Enclosure 3, Processor Card 5: Slots J0B, J0D, J1B, and J1D</li><li>Enclosure 2, Processor Card 4: Slots J0B, J0D, J1B, and J1D</li><li>Enclosure 2, Processor Card 3: Slots J0B, J0D, J1B, and J1D</li><li>Enclosure 1, Processor Card 2: Slots J0B, J0D, J1B, and J1D</li><li>Enclosure 1, Processor Card 1: Slots J0B, J0D, J1B, and J1D</li></ul>
