Hi Chris,
As many people mentioned, there are many solutions out there that can do the job. You have to make sure that you have the support of the dealer that sells you the solution.
Regarding the 8Gb fiber Atto, Qlogic have fiber cards and switch that is 8Gb the only questions remains is the storage capable of the delivering more bandwidth. in many cases you will not see much performance difference between 8Gb and 4Gb with a single storage array, it will increase the performance with a Pool of arrays.
On a long term if you invest into an 8Gb fiber switch and the SAN software the rest can be upgraded as you go in the future (Such as HBA’s and storage).
One more solution to look into is the Tiger MetaSan, it is a great software and a small SAN solution.
If you are interested to get some more feedback you can call me at 818-242-4996 x 112.
