It would be interesting to know what software use these SAN devices,
most of them are using Linux !
It's not software, it's definitely not Linux(!) - it's firmware.
(Unless you're talking Sun's new OpenStorage stuff, in which case it
could be OpenSolaris.) This is stuff that is all managed at the
storage *controller* level, not the host or its operating system.
Imagine a SCSI controller with a *large* brain and network
connectivity (to other storage devices).
SAN storage controllers can do block level replication between storage
units with no interaction from the computers connected to them. You
can also take snapshots of a volume and export them to a host(s).
