“As far as differentiation goes, take a look at Panzura. The Panzura Controllers are very fast, offering line speeds that match those of public cloud storage networks, and are feature heavy—with built-in support for CIFS, NFS, File Locking, Versioning, Snapshots, Compression, Dedupe, Cache—and the product supposedly works. It’s not a lab experiment that’s not ready for prime time and it’s not a low-end, scalability-challenged box with little more than a cool name going for it.”
