External Storage
HP has the broadest, most robust server and storage line up in the industry, providing exactly the right fit for every need.

AC/DC Power
DC Power Supplies
The HP Integrity rx7640 Server comes with two power supplies that provided dual grid (2N)
protection. The hot swap design allows for the replacement of a failed power supply without
interrupting server operation. All four power cords must be utilized to fully enable power supply
hot swap. HP Integrity rp7410/rp7420/rx7620 DC power supplies can be carried forward to the
HP Integrity rx7640 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 rp7410/rp7420/rx7620 PCI Power Supplies
cannot be carried forward to the HP Integrity rx7640 server.
AC Power
The HP Integrity rx7640 Server contains four C20 power receptacle ports located at the bottom
rear bulkhead. A minimum of two power cords must be used to maintain normal operation of the
HP Integrity rx7640 Server. A second set of two cords can be added to improve system
availability by protecting, for example, against power grid failures, accidentally tripped circuit
breakers, or a failed power supply. The HP Integrity rx7640 Server hardware is capable of
receiving AC input from two different AC power sources. The objective is to maintain full
equipment functionality when operating from power source A and power source B or A alone or
B alone. This capability is called "fault tolerant power compliance".
Although many HP Integrity rx7640 Server configurations can be sufficiently powered from a
single 16 /20 amp branch circuit, the optimum configuration is to use one 16 amp (minimum)
branch circuit per power cord. Due to the variety of 16/20 plugs used throughout the world, the
HP Integrity rx7640 Server Ordering Guide offers a choice of plug options.
AC Power Consumption
The HP Integrity rx7640 Server power consumption will vary greatly depending on the hardware
configuration and the input line voltages supplied at customer sites. Because of the disparity of
line voltages throughout the world it's best to represent power consumption in VA (Volt
Amperes). With power consumption being of high concern throughout the world, it's necessary
to specify consumption in a couple of different ways.
Maximum Theoretical Power:
or "Maximum Configuration" (Input power at the ac input
expressed as Volt-Amps to take into account Power factor correction.)
