Cntlr-Shelf (Controller-to-Shelf) – This means the cable is used to connect a storage controller (such as an AFF or FAS system) to a disk shelf. This connection allows the controller to manage the disk shelves in the storage system. Shelf-Shelf (Shelf-to-Shelf) – This indicates that the cable can be used to interconnect two disk shelves. This is important for expanding storage capacity by linking multiple disk shelves together. HA (High Availability) – This refers to a high-availability configuration where two controllers are connected to ensure redundancy and failover capabilities. In a NetApp HA pair, each controller can take over the other’s workload in case of a failure. Supported Protocols 40Gb QDR InfiniBand; SAS 3/6 Gb; SAS 3Gb; SAS 6Gb;
