HP-UX 11i is the first operating system release for the new
Superdome platform. Superdome systems' hardware and firmware
and HP-UX 11i allow a system to be configured into multiple partitions
that consist of one or more cells. A cell contains a maximum of
four CPUs, a maximum of 16GB of memory, plus I/O bridges and peripherals.
Adding cells to, or removing cells from, a partition will
require a reboot. This allows the system administrator to designate
a new configuration at any time before the reboot, after which the
new configuration will take effect.
Superdome partition technology increases the flexibility of
system workload management of a large system while maintaining the
benefit of application protection, as if running on separate small
systems. Configuring partitions is done with the Partition Manager
Graphical User Interface or from a new set of commands (see partition(1)). Partition
Manager can be launched from sam, directly from the command line using the /opt/parmgr/bin/parmgr command, or from a PC web browser.
Other key HP-UX support for the partition architecture is
included with the Superdome configuration commands, Superdome kernel
support (machine dependent code), and PCI Card Online Addition and Replacement
(OLAR).
