I'm having a heck of a time with ESX4i and a Dell branded Adaptec controller. It's an Adaptec 2960 6-port SATA card which worked well with an old underpowered system running ESX3.5. Under ESX4, the card just seems to fall all over itself. I've found through searching that the card is no longer recommended for ESX, so I find myself wondering what else I could use.
I was considering going to an ASUS M3N78-VM, which has 5 on-board sata ports, but I have seen on the communities that this won't work as I would like it to. I thought of going off of ebay and picking up a compatible 3Ware card, but I have read about other troubles on that front.
Is there one that won't break the budget that doesn't have issues? I'm tempted to just go the NFS route as that might be easier in the long run.
