Even a suboptimal configuration can result in a performance boost. The most interesting thing, I think, is the ease with which the zpool was created.

I wonder what kind of performance numbers this user would see with the 7110 compared with the Dell Powervault. The 7110 can hold 14 146gb sas drives, whereas the Dell uses 14 146gb scsi drives, so comparing power utilization would be interesting as well.
