zHyperLink adapters and cables
You can order zHyperLink adapters for your storage system configuration.
zHyperLink connections with IBM Z hosts provide low latency for random reads.
Storage systems with 12-core and higher processors are supported. I/O Priority
Manager must be disabled.
Note: The z-synergy Services license is required for zHyperLink.
Feature codes for zHyperLink I/O adapters
Use these feature codes to order zHyperLink I/O adapters for storage systems
with 12-core and higher processors.
Each zHyperLink connection requires a zHyperLink I/O adapter to connect the
zHyperLink cable to the storage system. Each zHyperLink I/O adapter card has
one port, but you must order them in sets of two. Depending on the system
configuration, zHyperLink I/O adapters can be ordered in quantities of 2, 4, 6, and
8.
