This Redpaper provides information on the PCI X Cryptographic Coprocessor (PCIXCC) and the PCI Cryptographic Accelerator (PCICA) on a z990 server. We describe cryptographic domains and z990 configuration rules considering the increased number of logical partitions. We review items that should be taken into consideration when planning for non-disruptive installation of PCICA and PCIXCC features.

We describe, step-by-step, how to define and configure cryptographic coprocessors to each logical partition from the Hardware Management Console (HMC). We also show the use of ICSF Coprocessor Management panels.

This Redpaper is intended for IBM systems engineers, consultants, and customers who plan to install zSeries 990 cryptographic features.
