The hosting environment within which a storage
system operates. The operating environment includes
the computer(s) to which the storage system is attached,
I/O buses and adapters, host operating system instances,
and any required software. For host-based disk arrays,
the operating environment includes I/O driver software
for the array and possibly also for the member disks,
but does not include Array Management Function,
which is more properly regarded as part of the array
itself.
