Explanation

zEDC Express (IBM z Express Data Compression) is the dedicated hardware feature on z14 and z14 ZR1 that offloads compression and decompression workloads from general-purpose processors, improving throughput while reducing CPU consumption for data-intensive tasks like zlib and gzip operations.

The distractors target other real z14 components but serve different purposes: Virtual Flash Memory (A) is a storage caching technology, not a compression accelerator. Crypto Express6S (C) is a hardware security module (HSM) designed for cryptographic operations like encryption and key management - not compression. 10GbE RoCE Express (D) is a network adapter providing high-speed, low-latency RDMA over Converged Ethernet connectivity.

Memory tip: The "C" in zEDC stands for Compression - if you see "Express" with compression on z14, it's zEDC Express. Think of "Crypto" for Crypto Express and "Compression" for zEDC to keep the two hardware accelerators distinct.
