Hardware Requirements

The hardware requirements for CA Tape Encryption are:

• Any hardware that supports z/OS 1.6 and above, and the IBM z/Architecture™ (ARCHLVL=2).
• The following processors are supported:
  • IBM z800
  • IBM z900
  • IBM z890
  • IBM z990
  • IBM z9
  • IBM z10
  • IBM z11
• The Cryptographic Coprocessor Facility (CCF) is not required for IBM z800 or z900 processors, however for optimal system performance CA recommends that you have one installed.
• You are not required to activate the CP Assist for Cryptographic Functions (CPACF) feature for IBM z890, z990, z9, or z10 processors; however for optimal system performance CA recommends that you activate it. (In most cases, CPACF is shipped in the enabled state on IBM z9 and z10 processors.)

  Note: The z9 Business Class (BC) and z9 Enterprise Class (EC) systems are supported, and are referred to in the documentation as z9. z9 zIIP specialty processors are optional but strongly recommended to improve performance and minimize central processors overhead.

You can use the Integrated Cryptographic Service Facility (ICSF) Cryptographic Key Data Set (CKDS) instead of the BES database to store your symmetric encryption keys if a cryptographic coprocessor is present.
