Cell Details
The HP 9000 rp7420 Server is a symmetrical multiprocessing (SMP) server supporting up to 8
high performance dual core PA 8900 (1.1 GHz or 1.0 GHz) or PA 8800 (1.0 GHz or 900 MHz)
processor modules. A dual core processor module supports two processors resulting in a 16processor core server. It also supports the sx1000 chip set. The rp7420 Server can be configured
as a single SMP server or divided into two smaller, hardware partitioned (nPars), logical servers.
A minimum of one and a maximum of two cells can be ordered in an HP 9000 rp7420 Server.
Each cell can be purchased with up to four active dual core PA 8900/PA 8800 processor modules
(8 processors), 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 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 rp7420 (8 processor module slots)
and HP 9000 rp8420 (16 processor module slots) servers share the same cell board. A processor
module slot contains 1 dual core processor module (2 processors). The HP 9000 rp7420 Server
cell board can be carried forward to the HP Integrity rx7620 and supported Itanium processors in
that chassis. The HP 9000 rp7410 cell board (A6096A) CANNOT be carried forward to the HP
9000 rp7420 Server and must be replaced (although previous HP 9000 rp7410 memory can be
carried forward). When replacing previous HP 9000 rp7410 cell boards in an upgrade situation,
cell board and PA 8700/8700+ return credits may be used.

Processors can be ordered individually (2 processors) or upgraded individually.
There must be at least one active core (non iCAP) processor on each cell board.
On each cell board, processors must be installed in the following sequence 0, 2, 1, 3
The memory DIMMs used in the HP 9000 rp7420 Server are sold in quads and are custom
designed by HP. Each DIMM contains 36×4 SDRAM memory chips qualified to run at 125 MHz,
with full ECC protection. DIMM sizes of 512 MB, 1 GB, 2 GB, and 4 GB are supported. HP 9000
rp7410 memory modules can be carried forward to the HP 9000 rp7420 Server. Each HP 9000
rp7420 Server cell board supports up to 16 DIMMs with 16 GB/s of peak memory bandwidth. The
16 GB memory modules (4×4GB DIMMs) cannot be mixed with other memory DIMM sizes. When
purchased from the factory, any given partition can ordered with 4 GB DIMMs or non stacked
DIMMs (512 MB, 1 GB or 2 GB), but not both. When field integrated, cell boards can contain 4 GB
DIMMs or non stacked DIMMs (512 MB, 1 GB or 2 GB), but not both.
The HP 9000 rp7420 and HP 9000 rp8420 servers share the same 2 GB, 4 GB, 8 GB, and 16 GB memory products.

I/O Architecture
A cell should be configured with a multiple of 8 DIMMs. It takes 8 DIMMs to populate both
buses. Populating only one of the two memory buses on a cell board will deliver only half the
peak memory bandwidth.
Load memory equally across the available cell boards.
If growth is planned for the system, then plan on configuring high density 4GB, 8-GB, or 16GB modules to minimize future memory slot constraints.
There are two types of memory latencies within the HP 9000 rp7420 Server:
1. Memory latency
that consists of a single cell or uses cell local memory.
2. Memory latency
cell interleaved memory is used. In this case 50% of the addresses are to memory on the same
cell as the requesting processor, and the other 50% of the addresses are to memory of the other
cell.
The HP 9000 rp7420 Server average memory latency depends on the number of processors in
the partition. Assuming that memory accesses are equally distributed across all cell boards and
memory controllers within the partition, the average idle memory latency (load-to-use) is as show
below:
Components within the I/O subsystem are the I/O controllers, internal peripheral bay, and
multifunction Core I/O. The figure below shows the basic block diagram of the I/O subsystem. The
HP 9000 rp7420 Server I/O architecture utilizes industry standard PCI buses in a unique design
for maximum performance, scalability and reliability.

The HP Integrity rp7420 Server contains two master I/O controller chips located on the PCI-X
backplane. Each I/O controller contains 16 high-performance, 12-bit-wide links; these links
connect to 18 slave I/O controller chips supporting the PCI card slots and core I/O. In the HP 9000
rp7420 Server, two links, one from each master controller, are routed through the system
backplane and are dedicated to core I/O. The remaining thirty links are divided among the sixteen
I/O card slots. This one card per link architecture leads to greater I/O performance and higher
availability. Each controller chip is also directly linked to a host cell board. This means that both
cell boards must be purchased in order to access all 15 available I/O card slots. (With only one
cell board, access to seven expansion slots is enabled.)
The HP 9000 rp7420 Server can be purchased with either one or two core I/O board sets. Each
Core I/O product contains two boards, a MP/SCSI and a LAN/SCSI card. The core I/O boards
provide console, Ultra160 SCSI, Gigabit LAN, serial, and management processor functionality. If
you opt for the second core I/O board set, it can be used to enable dual hard partitioning (nPars)
in the HP 9000 rp7420 Server and to provide access to a second set of disk drives.
The LAN/SCSI card provided with each Core I/O product occupies one of the sixteen PCI slots.
Since there must always be at least one Core I/O board set, the HP 9000 rp7420 Server has
fifteen available PCI slots for expansion cards. If the second Core I/O product (board set) is
purchased, there are fourteen remaining slots available for expansion cards.
The internal peripheral bay supports up to four low-profile disks and one removable-media device.
The internal disks are electrically divided into two pairs. SCSI controller chips located on each
