LinuxVTL

LinuxVTL is an implementation of a VTL in Linux. Not really an appliance, but some software which behaves like a real VTL. Do not expect the performance of a Protectier or a FalconStore, as the changelog show this is really work in progress : the log for one of the last changes shows fixes for silent data corruption.

Data-deduplication isn't included, but you can off course use FUSE-ZFS with dedup on. Also, if you're using LinuxVTL on a separate server, you know you must either have HBA cards, or use iSCSI.
