Partition Hardware Requirements

The physical hardware prerequisites, shown below, determine which

cells and I/O chassis are eligible to be conﬁgured in a partition.

Every partition you conﬁgure must meet the following basic hardware

requirements:

• Each partition must have at least two cells.

• The same ﬁrmware revision must be present on all cells.

• At least one cell in every partition must be connected to an I/O

chassis that has a core I/O card installed in PCI slot 0.

Note that only one core I/O card is active per partition.

If multiple core I/O cards are installed—that is, if a partition has

multiple cell-to-I/O chassis connections with more than one chassis

having a core I/O card—then only the core I/O connected to the core

cell is active.

• The I/O chassis containing the active core I/O card also should have

the following devices and cards installed:

— The HP-UX boot device (and FW SCSI or FibreChannel card)

— DVD-ROM (and Ultra SCSI card)

— Network card(s)

• All cells in a partition must have the same processor revision level

and processor clock speed.

• The memory conﬁguration of all cells in a partition must be identical

to achieve best performance and availability.

This means that each of a partition’s cells should have:

— the same number of DIMMs, preferably a multiple of 8 DIMMs

— the same capacity (size) and the same locations (population) of

DIMMs
