1.7 External SAS Connectors
The ARTM-HD includes two external SAS connectors. These connectors can be used
to connect additional disk packs, or to create redundancy between two ARTM-HDs
and their associated blade servers.
When connecting the ARTM-HD to an external disk array, use the Primary SAS port
connector.

When connecting to another ARTM-HD for redundancy, route the Primary port on
each ARTM-HD to the Secondary port on the other ARTM-HD.
