Memory Features; System Disks And Media Features - IBM Power 595 Technical Overview And Introduction

1.3.2 Memory features

The Power 595 utilizes DDR2 DRAM memory cards. Each processor book provides 32
memory card slots for a maximum of 256 memory cards per server. The minimum system
memory is 16 GB of active memory per processor book.
The Power 595 has the following minimum and maximum configurable memory resource
allocation requirements:
Utilizes DDR2 DRAM memory cards.
Requires a minimum of 16 GB of configurable system memory.
Each processor book provides 32 memory card slots for a maximum of 256 memory cards
per server. The minimum system memory is 16 GB of active memory per processor book.
Supports a maximum of 4 TB DDR2 memory.
Memory must be configured with a minimum of four identical memory features per
processor book, excluding feature #5697 (4 DDR2 DIMMs per feature). Feature #5697,
0/64 GB memory must be installed with 8 identical features.
Different memory features cannot be mixed within a processor book. For example, in a
4.2 GHz processor book (#4694), four 0/4 GB (#5693) features, 100% activated DIMMs
are required to satisfy the minimum active system memory of 16 GBs. For two 4.2 GHz or
5.0 GHz processor books (#4694 or #4695), four 0/4 GB (#5693) features, 100% activated
in each processor book is required to satisfy the minimum active system memory of
32 GBs. If 0/8 GB (#5694) features are used, then the same minimum system memory
requirements can be satisfied with 50% of the DIMMs activated.
Each processor book has four dual-core MCMs, each of which are serviced by one or two
memory features (4 DIMMs per feature). DDR2 memory features must be installed in
increments of one per MCM (4 DIMM cards per memory feature), evenly distributing
memory throughout the processor books installed. Incremental memory for each
processor book must be added in identical feature pairs (8 DIMMs). As a result, each
processor book will contain either four, six, or eight identical memory features (two per
MCM), which equals a maximum of 32 DDR2 memory DIMM cards.
Memory features #5694, #5695, and #5696 must be 50% activated as a minimum at the
time of order with either feature #5680 or #5681.
Features #5693 (0/4 GB) and #5697 (0/64 GB) must be 100% activated with either feature
#5680 or #5681 at the time of purchase.
Memory can be activated in increments of 1 GB.
All bulk order memory features #8201, #8202, #8203, #8204, and #8205 must be
activated 100% at the time of order with feature #5681.
Maximum system memory is 4096 GB and 64 memory features (eight features per
processor book or 256 DDR2 DIMMs per system). DDR1 memory is not supported.
For a list of available memory features refer to Table 2-15 on page 80.

1.3.3 System disks and media features

This topic focuses on the I/O device support within the system unit. The Power 595 servers
have internal hot-swappable drives supported in I/O drawers. I/O drawers can be allocated in
24-inch or 19-inch rack (IBM i application only). Specific client requirements can be satisfied
with several external disk options supported by the Power 595 server.
