CELLV Board

Each CELLV Board supports:

!4 Intel Itanium 2 processors

!16 DIMMs.

The system supports 2 CELLV Boards for a total of eight Itanium 2 processors and up to 32 DIMMs.

CPUs

Each CELLV Board supports 4 Itanium 2 processors. The system supports the following processor types:

!Intel Itanium 2 1.3GHz/3MB of level 3 cache

!Intel Itanium 2 1.5GHz/6MB of level 3 cache

The same type processor must be used in the system. The two types cannot be mixed within a single system.

Memory

Each CELLV Board supports up to 16 DIMMs in the following configurations:

!Memory must be installed in groups of 4 DIMMs of the same capacity.

!Memory capacity can vary between different groups

!At least one group of four DIMMs is required in the system.

!Each CELLV Board supports up to 4 groups of 4 DIMMs.

!A memory group currently includes a group of four 1-GB DDR DIMMs for total capacity of 4 GB in a group.

!Maximum memory capacity using currently available 1-GB DIMMs is 16 GB per CELLV board or 32 GB on two CELLV boards.

For detailed memory configuration information, see Appendix B. in this guide.
