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

Table 13 Maximum Number of Virtual Partitions Per Server
Maximum Number of Virtual PartitionsServer Model
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.
rp7400/N4000
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).
Superdome 2 (SD2) (Integrity)
Notes about Maximum Number of Virtual Partitions
• Table 13 assumes single path to I/O; if dual path is used, as in many mission critical
environments, then the recommended and maximum numbers may be half of that stated.
• The number of virtual partitions can be limited by the number of available IO slots.
• For PA-RISC systems, the number of virtual partitions can be limited by the size of the kernels.
In short, the sum of the kernel sizes must be less than 2GBs. For more information, see Memory
Allocation in the HP-UX Virtual Partitions Administrator Guide.
4.2.5 Minimum Virtual Partition Requirements
Each virtual partition requires a minimum of:
• 1 processing core
• Enough memory to run HP-UX 11i and applications. See the applicable HP-UX Install and
Update Guide for your OS for the minimum amount of memory.
• 1 unique boot device connected through SCSI or Fiber Channel card on a PCI bus or a Local
Bus Adapter (LBA) that is uniquely owned by that virtual partition)
• 1 unique LAN card on a PCI-bus/LBA that is uniquely owned by that virtual partition. On
Integrity systems, the LAN card must be bootable if you are installing the OE onto a virtual
partition using Ignite-UX. For more information on how vPars uses Ignite-UX, see the Chapter
4 of the HP-UX Virtual Partitions Administrator Guide.
Notes about Minimum Virtual Partition Requirements
• Each PCI bus/LBA is uniquely owned by 1 virtual partition. Therefore, the internal LAN card
and storage connections (associated with each core I/O card) can only be owned by a single
