Manual No 771961 G 3 Glossary External RAID Operation External RAID Controllers use their host ports to connect to one or more Host Bus Adapters in one or more host computer systems Depending on the model and configuration of the controller there may be from one to four host ports Each configured logical drive consumes a particular bus target ID LUN on the host system Multiple sets of disk drives are connected to the controller via its drive channels There may be as many as six drive channels depending on the controller model and configuration In duplex or Active Active mode two identical External RAID Controllers are connected to the same hosts via their host ports to the same drives via their drive channels and to each other via a special hardware link for heartbeat sensing This forms a redundant controller system The two controllers work together handling data traffic and mirror their write data in each other s cache memory If one of the controllers fails or otherwise becomes non operational the surviving controller takes over its responsibilities with no loss of data External RAID Controller The controller acts as a bridge between host channels and drive channels and implements the RAID function On the drive channels the controller acts as an initiator The host channel ports are implemented as target IDs with logical drives presented as LUNs under the target IDs Host to LUN Mapping The host to LUN ma
