NexentaStor is a proprietary derivative operating system built by the developers of the open-source Nexenta OpenSolaris-distribution that has been optimized for use virtualized server environments NAS and iSCSI and Fiber Channel applications built around the ZFS file system. It features iSCSI support, unlimited incremental backups or 'snapshots', snapshot mirroring (replication), block level mirroring (CDP), integrated search within ZFS snapshots and a custom API. Through its focus on ZFS, it carries with it potential benefits for virtualized server farms in terms of performance and thin provisioning. The operating system is currently distributed as ISO and VMWare disk images with pricing determined on a per-gigabyte and per-server licensing basis.^[1] A "developer's edition" is available free of charge for users with less than 4 terabyte of used disk space.^[2]
