I'm testing VMware in my lab. I just added a hardware RAID card (PERC 6/i) to my host and initialized two 500GB drives as RAID0. vSphere Client shows the adapter as vmhba1, transport: Parallel SCSI. The other adapters (vmhba0, vmhba32, and vmhba35 for ESX, datastore1, and cdrom) use an on-board controller and are all listed as Block Adapter.
Why does the RAID device use a different transport mode? What are the implications?
