This is a direct-attached configuration showing one (1) host
connected to one (1) RAID subsystem. Drives in the enclosure can
be configured into one or more arrays, and made available through
individual host ports.
Operating system(s) might boot from the array. Operating using a
protected capacity decreases the chance of server downtime. The
logical arrays can be associated with different host IDs on separate
host channels so that if one cable link fails, the host can still access
the arrays through another channel link. File locking or access
management utilities will be necessary to avoid access conflicts.
Depending on I/O characteristics, each configured array should be
properly optimized either for Random or Sequential I/Os.
Multiple logical drives or multiple partitions can be created and
made available separately through different ID/LUNs on the host
channels.
This topology does not provide path redundancy. If one of the host
channels becomes disconnected, or if the cable connecting one of
the host ports to the host computer is damaged, data flow will be
interrupted.
