the configuration change. The reboot of the partition only affects the partition that is being reconfigured.
The other partitions defined in the chassis are not affected and will continue to execute without
interruption. In a future HP-UX release, dynamic hard partitions will be supported. Dynamic partitions
imply that partition configuration changes do not require a reboot of the partition.
The HP Integrity rx8640 Server can be divided into four independent hardware partitions when configured
with the HP Server Expansion Unit 2. In a partitioned configuration, I/O bay resources such as I/O slots,
core I/O, disk and removable media bays, are always dedicated to the corresponding cell board slot. In
other words, I/O bay 0 resources are always configured to the cell board in Cell slot 0. Therefore, in a
partitioned system, the amount of resources within a partition is always proportional to the number of
cells within that partition. There is no flexibility to otherwise divide these components. For example, in a
system configured with two cells in separate nPars, it is not possible to include twelve I/O slots in partition
0 and four I/O slots in partition 1. Please refer to the "HP Server Expansion Unit 2" section in this
document for more specific details.
The table below summarizes the resource availability based on hardware partitions.

Software Partitioning

Software Partitioning HP Integrity rx8640 servers support virtual partitioning (vPars) to the single processor level similar to
support on HP 9000 servers with HP-UX 11i v1. With vPars, a user will be able to support up to eight
separate virtual partitions each with an instance of HP-UX within each hard partition. VPars will provide
many of the features of nPars but without the electrical isolation and support for hardware failures that
nPars provides.
HP Virtual Machines is supported on the rx8640 server. HP Virtual Machines:
increases server utilization
enables server consolidation
provides rapid deployment of new environments (a requirement for test and development
environments)
enhances the HP Virtual Server Environment by providing soft partitioning with shared I/O, sub
CPU granularity, and built in dynamic resourcing for all Integrity servers

HP Systems Insight Manager (SIM) is the central point of administration for management applications
that address the Integrity rx7640 and rx8640 server's management requirements. HP SIM delivers
powerful monitoring and control, notifying the administrator of potential hardware or software problems
before they occur. It also provides inventory reporting capabilities that dramatically reduce the time and
effort required to track server assets. HP SIM provides secure communications as well as role based
security to make certain that its powerful capabilities are kept secure from unauthorized users.
