Introduction
Open source NAS (Network Attached Storage) based on an embedded version of FreeBSD (nanoBSD) and released under 2-clause BSD license
Enterprise-grade appliance (TrueNAS) is also available in 2U/4U form factors with tiered professional support
Releases
8.0 was released in May, 2011 with a focus on NAS core functionality (redesign of .7x which was EOL'd in 2011)
8.2.0 introduced the original Plugins architecture for installing additional software (July 20, 2012)
8.3.0 introduced ZFSv28 (October 26, 2012)
8.3.1 introduced full disk encryption (March 20, 2013)
9.1.0 is latest release (August 1, 2013)
Core Features
Create UFS or ZFS volumes (ZFS recommended)
Import existing UFS/ZFS RAID/z volumes
Import existing UFS, DOS, NTFS, EXT2/3 volumes
Create shares using Appletalk, NFS, and SMB protocols
Configure access through FTP/SFTP, SSH, and iSCSI
Core Features
Integration with OpenLDAP, Active Directory
Automated, secure replication via rsync/ssh
Automated ZFS snapshots and scrubs
Front-ends to cron, sysctls, loader.conf
Reporting graphs, scheduled S.M.A.R.T. tests, automated alerts, UPS
Core Features
Link aggregation, failover, and VLAN support
DDNS, SNMP, and TFTP support
Control panel to stop/start and view the status of services
Supports OSX Time Machine and Windows Shadow Copies
Core Features
OS is installed on USB stick/CF and is separate from data on storage disks
Upgrades keep a backup of the old OS, allowing for rollback
Administrative GUI accessed through a web browser; 8.2 added a web shell for command line operations
PDF of Users Guide published with each software release
ZFS
128-bit filesystem designed to be “self-healing” with checksums to provide data integrity
Snapshots (point in time) only store what has changed since the last snapshot (COW)
Scheduled scrubs verify integrity of disks and data
Deduplication saves space (removes duplicate data)
Datasets have properties (quotas, compression)
ZFS
RAIDZ* levels designed to overcome hardware RAID limitations
RAIDZ1: equivalent to RAID5
RAIDZ2: double-parity solution similar to RAID6
RAIDZ3: triple-parity solution
Caveats: resilvering takes time and can stress disks
What's New in 9.1.0
Based on 9.1-STABLE:
Latest drivers and bug fixes
Adds newest ZFS feature flags, including LZ4 compression
Same ABI (Application Binary Interface) as PC-BSD PBIs (over 1100) means that there is more software available for installation
What's New in 9.1.0
Volume Manager:
UFS and ZFS now have separate managers
How to extend a ZFS pool or add log/cache devices is more intuitive
Easier to manage a large amount of disks
Estimated size of ZFS pool is displayed for selected RAIDZ* layout and GUI will not let you create an unsupported layout
ZFS Volume Manager
Plugins Easier to Use
Users no longer have to first configure a jail as the Plugins mechanism automaticaly creates and uses a default jail
New integrated AppCafe browser lists available FreeNAS PBIs, simply highlight the app and click its Install button
Appcafe.org (launching soon) will make it easy to find PC-BSD, pfSense, and FreeNAS PBIs
Plugins Easier to Use
Jails for Advanced Users
Users who want more control over software installations now have a choice of what type and how many jails to create and can install software using FreeNAS PBIs, PC-BSD PBIs, FreeBSD pkgng packages, or FreeBSD ports
The only required parameter when creating a jail is the name, however users can choose to configure other items such as the IPv4 and/or IPv6 address(es), MAC address, and whether or not to use vimage
