Losing power from a single power grid

Accidental tripping of one or two circuit breakers

Accidental disconnect of a single PDU power cord

Accidental disconnect of up to four (two from each system) system power cords

30 amp Power Distribution Unit-

252663 D75 (NA/JPN) and 252663 B33 (International)-supported for 10K G2 rack

E7681A (North America/JPN) and E7682A (International)-supported with Rack System E

A 30 amp Power Distribution Unit (PDU) is also supported with HP Integrity rx7640 Server.

Rack configurations consisting of peripherals and only one HP Integrity rx7640 Server will likely

be best supported with the 30 amp PDU. This PDU is sold separately and can be ordered with

any HP server solution.

Unlike the 60 amp PDU, each 30 amp PDU can only support one HP Integrity rx7640 Server.

The following configuration guidelines apply when using the 30 amp PDU:

A0 and A1 or B0 and B1 cords should never be plugged into the same PDU

Use two 30 amp PDUs to achieve input power redundancy (plugging A0/A1 and B0/B1

into separate PDUs).

Ordering tools will not force the purchase of a second PDU for input power redundancy. A

second PDU must be manually selected if redundant input power is desired.

Partitioning

A hardware partition corresponds roughly to a single, standalone system. Each HP Integrity

rx7640 Server can be subdivided into two partitions, each containing one cell that has minimal

shared resources with the other cell (partition). Special programmable hardware in the cells

defines the boundaries of a partition in such a way that the isolation is enforced from the

actions of other partitions. Each partition runs its own independent instance of the operating

system (HP UX 11i v3 and HP-UX v2, Windows, Linux, or OpenVMS). Applications cannot

span partitions since each partition runs its own instance of the OS, essentially functioning as a

stand alone server. However, different partitions may be executing the same or different

revisions of an operating system, or they may be executing different operating systems

altogether (such as HP UX, Windows, Linux, or OpenVMS), with OS availability.

Each partition has its own independent CPUs, memory and I/O resources consisting of the

resources of the cells that make up the partition. Resources may be removed from one partition

and added to another without having to physically manipulate the hardware just by using

commands that are part of the System Management interface. With a future release of HP UX,

using the related capabilities of dynamic reconfiguration (e.g. on line addition, on line removal),

new resources may be added to a partition and failed modules may be removed and replaced

while the partition continues in operation.

Partitioning the resources of the complex in this way makes it easy to run multiple application

environments on the same physical system; you can allocate physical resources and tune the

operating system running on each partition depending on the needs of the application (or the

most important application) you intend to run on it. Alternatively, you can configure the HP

Integrity rx7640 Server as a single partition, allowing all the resources to be focused on a single

set of tasks, for example a large online transaction processing application.

You can increase or reduce the processing power of a partition by adding or deleting cells (at

this release, you must shut down the operating system running on the affected partition(s)

before moving cells, and before configuration changes will take effect). Though the OS might

include commands for some configuration tasks, HP recommends you use the Partition

Manager (parmgr) to configure partitions.
