Shown below is an example showing logical drives each managed by a single RAID controller, host ports hubbed together, and access routes forming fault- tolerant pairs. Multiple IDs will appear through the host ports; namely, multiple RAID volumes will appear through a host data link. Host management software will be necessary to manage access contention and provide failover capability.
Because each channel’s host ports on controller A and controller B are hubbed together, a BID (ID managed by controller B) can appear through a host link to an SFP port on controller A.
