TIA,

You could use a server connected to a SAN as a sort of NAS. I do not know
what you mean by sharing the data in a transparent way amoung n
servers....yes you could share data from a nas amoung n servers. This NAS /
SAN combo is used by many vendors. Only one machine will see the lun as its
own, that machine would then share it out to the other machines, unless you
used a snapshot or a clone of that disk, but then the other servers would
have to be connected to the SAN.

I have, related to this last part of NAS vs SAN. Can we use SAN as a
NAS? I mean, can we share (the same) central data in a transparent way
among n servers? Will this work as a NAS on steroids? Is this
supported/used on any platform? Are we talking about exclusive or
concurrential disk accesses? Does this bring problems on data
consistency? (well, every machine sees the disks as their own...) Is it
possible at all?

TIA
