If you were starting out at such a level I'm certain they would suggest you go with a T800 chassis which would allow you to double that performance. The T400 and T800 are identical with the exception of the backplane(~10GBytes/sec vs ~46GBytes/sec), the number of controllers(max of 4 vs max of 8), and the number of disks(640 vs 1280).
