CEX7S performance

IBM has introduced the IBM 4769, the latest version of its PCIe Cryptographic Coprocessor family, on IBM Z® mainframes (z15® only), as crypto feature Crypto Express7S (CEX7S), feature code (FC) 0898/0899. The 4769 is also available for installation on x64 servers as machine type-model (MTM) 4769-001.

The CEX7S delivers improved throughput capacity over CEX6S when deployed in heavy load environments while maintaining similar performance characteristics under lighter load conditions.
