Galaxy GHDX2-2430S/R-24F4D Installation and Hardware Reference Manual
4-14 Subsystem Connection and Operation
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.
