Chapter 1. Introduction and general description 3
The PS701 blade server
The PS701 blade server (8406-71Y) is a single socket, single-wide 8-core 3.0 GHz POWER7
processor-based server. The POWER7 processor is a 64-bit, 8-core with 256 KB L2 cache
per core and 4 MB L3 cache per core.
The PS701 blade server has 16 DDR3 memory DIMM slots. The industry standard VLP
DDR3 memory DIMMs are either 4 GB or 8 GB running at 1066 MHz. The memory is
supported in pairs, thus the minimum memory required for PS701 blade server is 8 GB (two 4
GB DIMMs). The maximum memory that can be supported is 128 GB (16x 8 GB DIMMs).
The PS701 blade server has two Host Ethernet Adapters (HEA) 1 GB integrated Ethernet
ports that are connected to the BladeCenter chassis fabric (midplane). The PS701 also has
an integrated SAS controller that supports local (on-board) storage, integrated USB controller
and Serial over LAN console access through the service processor, and the BladeCenter
Advance Management Module.
The PS701 has one on-board disk drive bay. The on-board storage can be one 2.5-inch SAS
HDD. The PS701 also supports one PCIe CIOv expansion card slot and one PCIe CFFh
expansion card slot. See 1.5.8, “I/O features” on page 24 for supported I/O expansion cards.
The PS702 blade server
The PS702 blade server (8406-71Y +FC 8358) is a two socket, double-wide 16-core 3.0 GHz
POWER7 processor-based server. The POWER7 processor is a 64-bit, 8-core with 256 KB
L2 cache per core and 4 MB L3 cache per core. The PS702 combines a single-wide base
blade (PS701) and an expansion unit (feature 8358), referred to as double-wide blade, which
occupies two adjacent slots in the IBM BladeCenter chassis.
The PS702 blade server has 32 DDR3 memory DIMM slots. The industry standard VLP
DDR3 memory DIMMs are either 4 GB or 8 GB running at 1066 MHz. The memory is
supported in pairs, thus the minimum memory required for PS702 blade server is 8 GB (two 4
GB DIMMs). The maximum memory that can be supported is 256 GB (32x 8 GB DIMMs).
The PS702 blade server has four Host Ethernet Adapter 1 GB integrated Ethernet ports that
are connected to the BladeCenter chassis fabric (midplane). The PS702 also has an
integrated SAS controller that supports local (on-board) storage, integrated USB controller
and Serial over LAN console access through the service processor, and the BladeCenter
Advance Management Module.
The PS702 blade server has two disk drive bays, one on the base blade and one on the
expansion unit. The on-board storage can be one or two 2.5-inch SAS disk drives. The
integrated SAS controller supports RAID 0, RAID 1 and RAID 10 hardware when two HDDs
are used.
The PS702 supports two PCIe CIOv expansion card slot and two PCIe CFFh expansion card
slots. See 1.5.8, “I/O features” on page 24 for supported I/O expansion cards.
Note: The PS702 blade server can have a minimum of 8 GB memory based as per
architecture, but we recommend a reasonable ratio between cores and memory.
Note: For the PS702 blade server, the service processor (FSP or just SP) in the expansion
blade is set to IO mode, which provides control busses from IOs, but does not provide
redundancy and backup operational support to the SP in the base blade.
