FreeNAS vs Nexenta

FreeNAS and NexentaStor are storage operating systems based on OpenZFS. Both support the SMB and NFS sharing protocols, and disk encryption.

FreeNAS

FreeNAS is an operating system that can be installed on virtually any hardware platform to share data over a network. FreeNAS is the simplest way to create a centralized and easily accessible place for your data. Use FreeNAS with ZFS to protect, store, and back up all of your data. FreeNAS is used everywhere, for the home, small business, and the enterprise.

NexentaStor

Nexenta’s product NexentaStor is software for network-attached storage (NAS) and storage area network (SAN) services. NexentaStor was derived from the Nexenta OS based on the illumos operating system. The software runs on commodity hardware and creates storage virtualization pools consisting of multiple hard disk drives and solid-state drives. Data can be organized in a flexible number of filesystems and block storage, and files can be accessed over the widely used Network File System (NFS) and CIFS protocols, while block storage uses iSCSI or Fibre Channel protocols. NexentaStor allows online snapshots to be taken of data and replicated to other systems. For high availability Nexenta uses RSF-1 cluster to build a HA storage.
