FreeNAS is an embedded open source NAS (Network-Attached Storage) distribution based on FreeBSD, supporting the following protocols: CIFS (samba), FTP, NFS, TFTP, AFP, RSYNC, Unison, iSCSI (initiator and target) and UPnP. It supports Software RAID (0,1,5), ZFS, disk encryption, S.M.A.R.T/email monitoring with a WEB configuration interface (from m0n0wall). FreeNAS can be installed on Compact Flash/USB key, hard drive or booted from LiveCD.
EON stands for Embedded Operating system/Networking. It is the first embedded Solaris ZFS (Zettabyte File System) NAS (Network Attached Storage) distribution based on Opensolaris. It is a RAM based live/install image which runs from CD/DVD, USB or CF (compact flash) and Disk on Module
EON focuses on using a small memory footprint so it can run from RAM while maximizing the remaining free memory (L1 ARC) for ZFS performance. Running from RAM removes the OS install disk as a point of failure. And if your hardware fails, no costly measures are needed to get your data. Simply attach the disks to another machine and with a ZFS capable operating system or EON.
Hardware Requirements: - 32/64-bit x86 processor (64-bit preferred) - 768Mb RAM minimum, 2GB good, 4GB+ high performance - 2 or more identical size disks. 3 identical sized disks minimum for RAIDZ. 4 identical sized disks minimum for double parity or RAIDZ2.
