We're using NexentaStor here. We do Dell R720 front-ends and Dell PowerVault MD1200 JBODs. We go up to about 1PB (3TB disks) raw per "stack" before starting a new one. Likely will try Dell's MD3260 JBOD at some point (super-dense 60-disk per 4U option). It's all SAS w/ LSI switches and triple parity RAID (RAIDZ3). So far have been very pleased. We'll even do a JBOD or two of SSD to accelerate reads/writes. Highly recommend you have Solaris experience though. The Nexenta GUI is improving, but still rough around the edges. If you want to save more $$ (at the risk of more headaches) you could do something similar with OpenIndiana on the same hardware. In any case, hard to beat the bang for the buck with the Dell hardware and all of the functionality you get with ZFS. We do have NetApp and XIV elsewhere, but it's very costly of course.
