•
This is a direct-attached configuration showing two (2) host computers
sharing the storage volume of one (1) RAID subsystem. Disk 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 controller IDs on different host channels so that if
a 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 RAID partitions can be created and made
available separately through different ID/LUNs on the host ports.
4.4.2 Direct-attached
Connections with Data Link Fault
Tolerance
This is a direct-attached configuration making use of all connection points and
shares storage with four (4) host computers, each of the host computers with two
(2) single-ported HBAs for path redundancy.
