HP rp8420, Overview, Page: 5 / 22

Configuration Configuration Configuration Configuration The HP 9000 rp8420 Server is a symmetrical multiprocessing (SMP) server supporting up to 16 high
performance dual core PA-8900 (1.1 GHz or 1.0 GHz) processor modules. A dual core processor
module supports two cores resulting in a 32 core server. It also supports the new and improved sx1000
chip set. The rp8420 can be configured as a single SMP server or divided into up to four smaller,
hardware partitioned (nPars), logical servers.
Cell Boards
Cell Boards Cell Boards
Cell Boards A minimum of one and a maximum of four cells can be ordered in an HP 9000 rp8420 Server. Each
cell can be purchased with up to four active dual core PA-8900 processor modules (eight cores), or in
combination with Instant Capacity processors. Four processor speeds are supported; 1.1 GHz and 1.0
GHz (using PA-8900) or 1.0 GHz and 900 MHz (using PA 8800). The ability to mix PA 8800 or PA
8900 processor speeds within a chassis is supported (but processors within a cell or partition must be of
the same speed). PA-8800 and PA-8900 may be mixed within the same chassis provided they are
placed in different hardware partitions. PA-8800/PA-8900 and PA-8700+ processors may not be mixed
in the same server. The HP 9000 rp8420 Server (16 processor module slots) and HP 9000 rp7420 (8
processor module slots) servers share the same cell board. A processor module slot contains 1 dual core
processor module (two cores). The HP 9000 rp8420 Server cell board can be carried forward to the HP
Integrity rx8620 and supported Itanium processors in that chassis. The HP 9000 rp8400 cell board
(A6096A) cannot
cannot cannot cannot be carried forward to the HP 9000 rp8420 Server and must be replaced (although
previous HP 9000 rp8400 memory can be carried forward). When replacing previous HP 9000 rp8400
cell boards in an upgrade situation, cell board and PA-8700/8700+ return credits may be used.
