Overview of FreeNAS

What is FreeNAS?
Open source NAS (network attached storage) based on FreeBSD and released
under a 2-clause BSD license.
● 11.0-U4 is the latest STABLE version (September 23, 2017)
● 11.1 is the upcoming new feature release (October, 2017)

Core Features
● Uses OpenZFS, a self-healing file system well suited for storage
● Built-in file sharing protocols include AFP, NFS, and SMB
● Built-in block protocols include iSCSI
● Also supports access through FTP/SFTP, SSH, and WebDAV
● Integration with OpenLDAP, Active Directory, NIS
● Automated, secure replication via rsync/ssh
● Automated ZFS snapshots and scrubs

Core Features
● Front-ends to cron, sysctls, loader.conf
● Reporting graphs, scheduled S.M.A.R.T. tests, automated alerts, UPS
● 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 or SSD 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; there is a web shell for
command line operations.

Boot Environments
Boot device formatted with ZFS with support for boot mirrors; boot menu supports
multiple boot environments (BEs).
Boot Manager allows you to create BEs on demand and prune old BEs.
Update Manager automagically creates a new boot environment when applying
system updates.
Revert to a previous version of OS by selecting its entry from boot menu.

Update Manager
Update Manager supports tracking of multiple “trains”.
As new drivers, features, bug fixes become available for tracked train, Alert is
issued and email sent to administrator.
Displays the Changelog and Release Notes for each update so that the
administrator can decide if and when to apply the update.

What’s New in 11

General Features
Continuation of the 9.x series, but with base operating system updated to FreeBSD
11-STABLE. This brings in many new and updated drivers and significant features,
including important speed improvements for 40/100GigE networking.
Updated OpenZFS adds the skein and SHA512 hash functions Feature Flags.
Samba, NFS, Netatalk, and Python updated to latest versions (including security
fixes).

New Feature: New UI Demo
Login screen now includes a link to “Demo our upcoming UI!”
New UI is based on Angular and uses C3.js for charts.
Faster as uses AOT (ahead of time) as opposed to JIT (just in time).
Uses WebSockets and when complete will have a documented REST API.
Currently a WIP (alpha), will be beta for 11.1 (October, 2017) and old UI parity
complete for 11.2 (early 2018).

New UI

New Feature: Alert Services
Configure important alerts to be sent to external services, including:
● AWS-SNS
● Hipchat
● InfluxDB
● Slack
● Mattermost
● OpsGenie
● PagerDuty
● VictorOps

Alert Services Configuration

New Feature: Enhanced Services Screen

New Feature: VMs
In addition to Jails and Plugins, you can now create and manage VMs.
VMs are based on bhyve, a BSD-licensed hypervisor for running guest operating
systems inside a virtual machine.
Supported guests include: FreeBSD, OpenBSD, NetBSD, CentOS, Debian, Fedora,
OpenSUSE, Ubuntu, SmartOS, Windows, and Windows Server.
This version provides limited support with new features being added for 11.1.

Creating a VM

New Feature: S3 Service
Provides the ability to build hybrid and private S3-compatible object storage
services, allowing fast access to locally hosted object stores.
Currently compatible with Amazon S3 cloud storage, other providers may be
added in the future.

Adding an S3 Storage

Sneak Peek of 11.1

General Improvements
Newer OpenZFS provides much faster performance, including when deleting a
large number of snapshots and when replicating snapshots.
Ability to pause/resume a scrub.
Sync with latest FreeBSD-STABLE and ports tree brings in latest drivers, features,
and updates base applications to latest versions.
Mirrored swap partitions means a failed disk won’t crash apps using swap.
Middleware now uses Python asyncio which simplifies asynchronous code and
makes it more readable.

New Feature: Resilver Priority!
Can now set a resilver schedule to take advantage of off-peak hours or weekends.
Schedule directs the resilver process to be more or less aggressive in its I/O
usage.
