TrueNAS CORE is a UNIX-based storage server that allows you to build a robust RAID storage system at low cost, leveraging the advanced features of ZFS.
Because ZFS is implemented in software, there is no need for expensive RAID controllers, reducing both hardware costs and the complexity of dealing with hardware component failures.
With its Copy-On-Write (CoW) mechanism, ZFS enables low-cost snapshots of block devices and file systems. This makes it possible, for example, to restore files on the storage server with a single click to a pre-infection state, even if a Windows client becomes compromised by ransomware.
Storage resources on the server can be shared not only via SMB (Windows file sharing) but also through NFS, iSCSI, and other protocols.
At UII, we have been evaluating and operating ZFS storage since the earliest releases of ZFS on FreeBSD. This long-standing experience enables us to provide specialized technical support for every stage of storage server implementation, operation, and disaster recovery.
