We had a look an Infortrend array (SATA internally, SCSI externally) and
had a lot of problems - it looked like problems in the array 'leaked'
through to the host - e.g. a failed disk caused the external SCSI bus to
reset etc.
Internal problems like this with the raid disks should be handled by the
raid controller - the host should be unaware of these problems.
Because of these problems, we rejected the Infortrend ...
