I've just purcheased a couple of adaptec controller (2405/5405) for my ESXi 4.0 U1 servers. Currently ESXi and a couple of VMs are hosted on single sata boot disk connected to a nvidia on board non-RAID controller.
I know that it's possible to migrate from single disk to RAID 1 with adaptec and I'm pleased with that, but I'm not sure if ESXi has already the right drivers installed/loaded for this controller.
Is there any way I can check this? Is ESXi clever enough to recognize the new hardware and load the right module?
