Table 4-8 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.

Notes about Maximum Number of Virtual Partitions
• Table 4-8 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. See “Memory Allocation”
in the HP-UX Virtual Partitions Administrator’s Guide for more information.
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. See the Chapter 4 of the HP-UX Virtual Partitions Administrator’s
Guide for more information on how vPars uses Ignite-UX.
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 virtual partition. All other virtual partitions require a separate LAN card for network
connection, and external storage (and associated SCSI/FC connections to that storage for
boot).
• An LBA is typically equivalent to one I/O slot.
• LBAs cannot be daisy chained.
• The LAN and boot device, unique to a virtual partition, can be combined into 1 LBA though
a supported combination card.
