Which IBM Z I/O adapter can connect to an IBM storage device?

The correct answer is C. zHyperLink Express. zHyperLink Express is specifically designed as a direct, ultra-low-latency storage link between IBM Z systems and IBM DS8900F (and DS8880) storage arrays - it is the only adapter in this list purpose-built for storage connectivity. OSA-Express6S GbE is a network adapter (Open…

Explanation

zHyperLink Express is specifically designed as a direct, ultra-low-latency storage link between IBM Z systems and IBM DS8900F (and DS8880) storage arrays - it is the only adapter in this list purpose-built for storage connectivity. OSA-Express6S GbE is a network adapter (Open Systems Adapter) used for LAN/WAN Ethernet connectivity, not storage. Crypto Express6S is a dedicated cryptographic coprocessor for encryption and key management - it has nothing to do with I/O or storage paths. ICA SR (Internal Coupling Architecture Short Reach) connects IBM Z nodes within a Parallel Sysplex coupling fabric, not to storage devices.

Memory tip: Focus on the word "Link" in zHyperLink - think of it as a direct hyperfast link straight to your storage. Every other adapter in the list has a giveaway in its name: OSA = networking, Crypto = encryption, ICA = coupling/clustering.
