I used three of the first-gen T540's and one T880 at my previous workplace. The T540's ran production Oracle and SQL databases, BI systems, RDS farms, production apps, and 200+ VDI desktops without breaking a sweat. Snapshots and cloning are a breeze and those features integrate with vCenter. Tintri has a scripting environment as well for bulk VM cloning, snapshotting, replicating, etc. My favorite part was the super fast setup time and near-zero administrative effort required to maintain them. They smoked Netapp all day long for a fraction of the price and hassle.
