Chapter 4. Cryptography 169

The Cryptographic Coprocessor modules on the z900 server are designed as Single-Chip

Modules (SCMs) mounted on the processor board and individually serviceable. This

eliminates the need to change the Multi-Chip Module (MCM, where they previously resided)

in the event of a Cryptographic Coprocessor module failure.

4.2.3 PCI Cryptographic Coprocessor (PCICC) feature

The Peripheral Component Interconnect Cryptographic Coprocessor (PCICC), feature code

0861, is an orderable feature that adds additional cryptographic function and cryptographic

performance to the z900 server general purpose models.

The PCICC feature coexists with and augments the integrated Cryptographic Coprocessor

that is standard on the z900 server general ...
