Rules and Guidelines for Conﬁguring a Complex

Appendix A 327

Guidelines for Performance and High Availability

In general, what you do to improve performance will also improve

availability. Exceptions are noted below.

Read the guidelines that follow in conjunction with “Partitions, Cells and

I/O Chassis” on page 333.

When To Add Cells

• Use all the possible resources within existing cells before

adding cells to a partition.

Example: If you need eight processors and 32 GB of RAM, conﬁgure

a partition containing two cells with four active processors and 16 GB

of RAM each, rather than four cells with two active processors and 8

GB of RAM each.

This guideline will help ensure the best performance; but there may

be cases in which you want to add cells for the sake of high

availability.
