Hello Nick,

the question is, what are you doing with it and why do you think you
need a fibre channel SAN.
Our goal indeed is to get rid of the SAN infrastructure as it is
delicately to all kinds of failure with nearly zero fault tolerance.
An example, you have an hicup or a power failure in your network. SAN is
dead from nowon and must be reinitialized on the server. Simple NFS
comes back up without any fuzz.
Another, you boot your storage systems due to an os update or something
like that. Your SAN will be dead. NFS will just go on as if nothing
happened.
We use netapp storage systems which are NAS and SAN capable.
Another point is, that if you have a SAN lun, there is either no way to
increase or decrease size on the fly, on cifs or nfs you can resize your
share on the go.

So if you do not have a _really_ good reason to use a fribre channel
SAN, don't!

Regards,
Norman
