IBM 4767 product support

This page provides product support information for customers of IBM’s 4767, a PCIe hardware security module (HSM) Cryptographic Coprocessor.
The IBM 4767 is available on x64 servers as an IBM Z® machine type-model 4767-002.

The 4767 is supported on IBM Z mainframes (currently only z14®, z13s™, and z13®) as crypto feature Crypto Express5S (CEX5S), feature code (FC) 0890. Note that FC 0890 requires FC 3863 - CPACF Enablement (Central Processor Assist for Cryptographic Functions). CPACF is a set of cryptographic instructions providing improved performance through hardware acceleration. Using the cryptographic hardware, you gain security from using the CPACF and the Crypto feature through in-kernel cryptography APIs and, for Linux® on z Systems®, the libica cryptographic functions library.

On IBM POWER8® systems, the 4767 is available as FC EJ32, Customer Card Identification Number 4767 (without blind-swap cassette custom carrier) and as FC EJ33, Customer Card Identification Number 4767 (with blind-swap cassette custom carrier), either on IBM AIX®, IBM i®, or PowerLinux® (Red Hat® Enterprise Linux (RHEL), SUSE® Linux Enterprise Server (SLES), to or Ubuntu®) operating systems.
