Isn't the 9271-8iCC newer tech than the 9260CV-8i? I thought it was when I compared the overall specs of both.Multiple cards will cost an extreme amount of money if you add the CacheVault option to each. And you cannot create arrays with drives on different controllers. Combining SATA drives with SAS expanders may not be the optimal solution, but it works in most cases. If you don't mind that a newer model exists you can also buy the 9260CV-8i which includes CacheVault.
