Expansion Unit 2 (SEU-2)
Additional I/O resources can be obtained by adding the HP Server Expansion Unit 2 (SEU-2). The SEU-2
is an add on chassis containing I/O resources that complement the I/O and partitioning capabilities
within the HP Integrity rx8640 Server. The SEU-2 mirrors the I/O resources embedded within the HP
Integrity rx8640 Server chassis, adding 16 I/O card slots, 4 disk bays, 2 removable media slots, and
enabling 2 additional hard partitions.
The SEU-2 must be installed in the same cabinet and directly above the host rx8640 server. Please refer
to the Server Expansion Unit 2 section in this guide or more specific details.
The following table summarizes the I/O configuration rules when an SEU-2 is configured with the HP
Integrity rx8640 Server.

External Storage HP has the broadest, most robust server and storage line up in the industry, providing exactly the right fit
for every need. Refer to the Storage Server matrix to see a matrix that highlights which storage device,

DC Power Supplies
The HP Integrity rx8640 Server supports up to six hot swap bulk power supplies for 2N+1 protection.
The hot swap design allows for the replacement of a failed power supply without interrupting server
operation. Two supplies are included with the base system. A minimum of one additional supply is
required for each cell board. Following this rule, all configurations will have 2N+1 power protection. HP
Integrity rp8400/rp8420/rx8620 DC power supplies can be carried forward to the HP Integrity rx8640
server.

PCI Power Supplies
PCI power supply is now a redundant N+1 design. One PCI power supply failure will not affect the I/O
bay since the remaining PCI power supply will power both I/O bays (this is an upgrade from the sx1000
based systems). PCI power supplies are hot swap capable (this is an upgrade from the sx1000 based
systems). HP Integrity rp8400/rp8420/rx8620 PCI power supplies cannot be carried forward to the HP
Integrity rx8640 server.
