Contact qualified personnel, such as your System Administrator or
an NEC Technician, for adding or removing server components.

Cell Board

Each Cell Board supports:
!
4 Intel Itanium 2 processors
!
32 DIMMs (16 on the Cell Board, 16 on the Cell Board daughterboard).
The 16-way server supports up to 4 Cell Boards for a total of 16 Itanium 2 processors
and up to 32 DIMMs per board.
The 32-way server supports up to 8 Cell Boards for a total of 32 Itanium 2 processors
and up to 32 DIMMs per board.

CPUs

Each Cell 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 Cell Board with memory daughterboard supports up to 32 DIMMs (16 on the Cell
Board, 16 on the daughterboard) 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 Cell Board supports up to 4 groups of 4 DIMMs; each memory
daughterboard supports up to 4 groups of 4 DIMMs.
!
A memory groups includes four 1-GB DDR DIMMs for total capacity of 4 GB in
a group.
!
Maximum memory capacity using currently available 1-GB DIMMs is 32 GB
per Cell Board with memory daughterboard.
