I agree. I have many people that want to purchase a SAN because someone
told them that is what they need... Yet they can spend 20% of the cost
on two external arrays and get incredible performance...

We are seeing great numbers from the following config:

(2) HP MS 30s (loaded) dual bus
(2) HP 6402, one connected to each MSA.

The performance for the money is incredible.

Sincerely,
