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 BoardsCell 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

cell boards in an upgrade situation, cell board and PA-8700/8700+ return credits may be used.

Memory Configuration

Memory Configuration
The memory DIMMs used in the HP 9000 rp8420 Server is sold in quads and is 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 rp8400 memory
modules can be carried forward to the rp8420 server. Each HP 9000 rp8420 Server cell board supports
up to 16 DIMM slots and 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.

Memory Loading Rules
Memory Loading RulesMemory Loading Rules
Memory Loading Rules
Memory must be installed in quads (4 DIMMs of equal density)
Memory is available in four densities: 2 GB (4×512MB), 4 GB (4×1024MB), 8 GB
(4×2048MB), and 16-GB (4 x 4096MB)
Minimum memory is 2-GB per cell
Maximum memory per system is 256 GB-using sixteen 16 GB Quads.
On each cell board, Memory Quads must be installed in the following order:
1st (0A, 0B, 1A, 1B), 2nd (2A, 2B, 3A, 3B), 3rd (4A, 4B, 5A, 5B), 4th (6A, 6B, 7A, 7B)

Guidelines
GuidelinesGuidelines
Guidelines
For best performance, a cell should be configured with a multiple of 8 DIMMs or two quads
(although the server will execute properly with an odd number of quads. 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 4, 8-GB, or 16-GB
modules to minimize future memory slot constraints.
Memory Latencies
Memory LatenciesMemory Latencies
Memory Latencies
There are two types of memory latencies within the HP 9000 rp8420 Server:
Memory latency
within
withinwithin
within
the cell refers to the case where an application either runs on a partition
that consists of a single cell or uses cell local memory.
Memory latency
between
between between
between
cell refers to the case where the partition consists of two or more cell
and cell interleaved memory is used. For example, for an rp8420 Server with four cells in the
partition, 25% of the addresses are to memory on the same cell as the requesting processor, and
the other 75% of the addresses are to memory on the other three cells.
The HP 9000 rp8420 Server memory latency depends on the number of processor modules 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 shown below:

I/O Architecture
I/O ArchitectureI/O Architecture
I/O Architecture
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 I/O
architecture utilizes industry standard PCI buses in a unique design for maximum performance,
scalability and reliability.
The HP 9000 rp8420 Server contains two master I/O controller chips located on the PCI-X backplane.
Each I/O controller contains sixteen high-performance 12-bit wide links, which connect to sixteen slave
I/O controller chips supporting the PCI-X card slots and core I/O. Two links, one from each master
controller is routed through the crossbar backplane and is 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 at least two cell boards, located in cell slots 0 and 1, must be purchased in order to
access all sixteen I/O card slots. With one cell board, access to eight slots is enabled.
The HP 9000 rp8420 Server can be purchased with either one or two core I/O boards (If an SEU is
added, then 4 core I/O boards with 2 Core I/O in the SEU). Both core I/O boards are identical and
provides console, SCSI, serial, and Management Processor (MP) functionality. The second core is used to
enable the dual partitioning in the HP 9000 rp8420 Server and provide access to a second set of disk
drives.
The internal peripheral bay is divided into two identical halves. Each half supports up to two low-profile
disks and one removable media device. A SCSI controller chip located on each core I/O board supports
each half of the internal peripheral bay. This means that both core I/O boards must be purchased to
access both halves of the peripheral bay.
PCI-X Backplane
PCI-X BackplanePCI-X Backplane
PCI-X Backplane
Fourteen of the sixteen I/O card slots are supported by dual high-performance links. Each link is capable
of providing 530 MB/s of bandwidth. This means that most HP 9000 rp8420 Server I/O slots are
capable of sustained 1.06 GB/s. Aggregate I/O slot bandwidth is 15.9 GB/s. In addition, because each
I/O slot has a dedicated bus, any slot can be "hot-plugged" or serviced without affecting other slots. The
hot-plug operation is very easy, and can be done with minimal training and effort.
The HP 9000 rp8420 Server supports a number of PCI and PCI-X HBA (I/O) cards for I/O expansion
(see Table below). Note that the PCI-X backplane is backward compatible with the older PCI backplane
and can support many PCI HBA (I/O) cards.
When HP 9000 rp8400 servers are upgraded to HP 9000 rp8420 servers using the chassis upgrade kit
A9785A, the older and slower PCI backplanes in the HP 9000 rp8400 server are upgraded to the newer
and faster PCI-X backplanes of the HP 9000 rp8420 Server.
When the rp84xx/px86xx Server Expansion Unit is connected to the HP 9000 rp8420 Server, its I/O
backplanes act as PCI-X I/O backplanes. See the rp84xx/px86xx Server Expansion Unit section for more
details.
