3682-8202 - IBM Power7 E4B, 6M SAS CABLE, ADPTR TO ADPTR (AA)

IBM Power7 8202-E4B (#3682) - 6M SAS CABLE, ADPTR TO ADPTR (AA)

The dedicated 2:6 cable connects between the dedicated top port on #5904, #5906 or #5908 for a SAS RAID Dual controller configuration providing (higher performance) path for all the dual controller communication including the mirroring of Write Cache and Parity update footprints between the adapters.

If the cable fails or is disconnected for some reason, then the "traditional" dual controller communication path via the SAS fabric (i.e. through the common disk expanders) is used for the adapter-to-adapter communication (mirror Write Cache, Parity Update footprints, etc...). This cable provides higher performance and redundancy. The cable is required for dual SAS RAID configuration. It is not required nor used for a single SAS RAID adapter (standalone) configuration.

Attributes provided: Higher performance path for all the dual controller communication including the mirroring of Write Cache and Parity update footprints between the adapters.

Attributes required: Two of any combination of the following SAS RAID adapters #5904, #5906 or 5908.
