SAN centralization

[djessi]

Hi,
I have almost 7 small SAN (servers, switches, disk bay)and
I would like to built one SAN (scalable)made of the 7 Sans.
How to proceed ?
THanks

choose a scalable core edge solution with a pair of director switches as the core of your san. Just hook up the rest to that ...

rgds,

R.

Thanks for your answer.
Does that mean that I have 2 zoning to do ?
One at director switches level and the other one
at the rest of switches level ? Does that mean a
zoning into a zoning ? How to allocate disk space
to servers ?
Regards
Djessi

You will just have one fabric to manage. The zones will distribute to all switches that are a member of the fabric.

Device "masking" combined with old fashioned zoning is how you allocate LUNs to servers. Device masking is generaly a software feature internal to the storage unit that determines which host WWN can see which LUNs on the same target fibre port. This functionality can be done at the switch level too if supported by your hardware.

There's devices like NetApp's V3000 which sit in front of SANs and give you a common inferface, never used one though so couldn't tell you how well they work...
