The HP Smart Array P410 and P410i controller is a 6G SAS based controller. In certain tests the performance is comparable to, for example, a Smart Array P800 controller (a 3G SAS based controller). However, the performance is degraded in other tests.
Note: All tests performed included the BBWC (Battery Backed Write Cache) installed and enabled on the P410(i).
HP and VMware recommend upgrading to ESX 4.0 or later.
