It is advisable to calculate performance against the host port
bandwidth when you design an application topology. As shown
below, if a RAID5 logical drive consisting of six (6) member
drives is associated with a host ID and made available through a
host channel, it would exceed the bandwidth of a single channel.
In this case, it will be a good practice to map this logical drive to
another host channel and use multi-pathing mechanism
(EonPath) to manage the redundant paths and do load-
balancing. In this w

Besides the above, there are still other considerations. For
example, a spare drive carries no data stripes and will not
contribute to disk-level performance. Please refer to the
