HP-UX Virtual Partitions Ordering and Configuration Guide (September 2012)

3
The minimum firmware required for vPars A.05.02 supports the dynamic memory migration feature of vPars, as well as
use of vPars on a system with Hyperthreading enabled (HT ON). Please note that hardware, operating system, or other
applications may have other requirements.
4
A firmware upgrade beyond the minimum firmware for vPars A.05.02 is necessary only if you need support for the vPars
tape boot feature on Integrity servers.
5
This firmware is added to the system on a special scree board (1253-5394). Customers should either download the
latest version firmware on their system before installing vPars, or contact their HP Service Representative for help. For
more information, please go to the HP IT Resource Center at http://www.hp.com/go/hpsc. The firmware is available
at ftp://ftp.itrc.hp.com/firmware_patches/hp/cpu/.

If you are upgrading the Superdome firmware, the upgrade must be performed by Hewlett-Packard qualified service
personnel only. Please contact your local HP Support Representative to schedule a convenient time for this firmware
upgrade service. Please note that all cells within the Superdome should be upgraded to the same level.

This firmware is available for download from the http://hp.com website. For details, see Downloading Server Firmware
(page 28).

The complex firmware bundle 2.51.102 or later must be installed to SD2 to support Dynamic Core functionality.
4.2.4 Number of Virtual Partitions per nPartition
The recommended number of virtual partitions per nPartition is equal up to one-half the installed
CPUs (processing cores) in the nPartition in order to meet I/O and memory requirements and to
allow for cores that can be used for dynamic processing core migration.
The maximum number of virtual partitions per system is the number of processing cores given the
limits specified in Table 13.

4 virtual partitions per system.rp5470/L3000, rp5405
8 virtual partitions per system using the combination card
A5838A (PCI 2-Port 100Base-T 2-Port Ultra2 SCSI) for
boot.
7 virtual partitions when not using the combo cards.

8 virtual partitions per system. This is a 2-cell system.rp7405, rp7410
8 virtual partitions per nPartition. This is a 2-cell system.rp7420, rp7440, rx7620, rx7640
8 virtual partitions per nPartition, 16 total per system with
no SEU and 32 total per system with SEU. This is a 4-cell
system.
rp8400
8 virtual partitions per nPartition, 16 total per system with
no SEU and 32 total per system with SEU. This is a 4-cell
system.
rp8420, rp8440, rx8620, rx8640
8 virtual partitions per nPartition, where the nPartition is a
maximum of 8 cells; 128 total per Superdome system for
the 128-way Superdome systems, where the nPartition is
a maximum of 8 cells. Note that vPars can now span
multiple cabinets.
Superdome (PA-RISC), Superdome (Integrity)
4 virtual partition maximum per blade.
16 virtual partitions maximum per nPartition.
NOTE: Both the conditions must be met. The maximum
number of blades for single nPar is 16. The maximum
number of cores per vPar is >64 cores (128 cores).
