Unbelievably inexpensive networked storage options have emerged, but it’s a case of ‘False Economics 101.’
PCMag has a post advising how to avoid the pitfalls of cheap storage:
The proliferation of huge, cache-laden SATA disks in the consumer market has led to an ever-expanding array of very inexpensive networked storage products for business. More often than not, these devices offer both NAS and iSCSI SAN functions that, until recently, were found only in enterprise-class storage products — at a fraction of the cost. Are these ultracheap alternatives right for you? That depends on who you are and what you do.
A huge range of performance variables separate true enterprise-class storage products from their inexpensive pretenders. The most glaring is transactional performance. Most low-cost storage devices are based on a small number of very large SATA disks rather than larger numbers of SATA or higher-speed SAS/FC disks. These types of configurations will yield extremely anemic transactional performance, which would generally make them poor choices for hosting a busy database or mail server.
What if that’s not what you want, though? If you’re a small business without a whole lot of transactional disk performance needs or a big business that just needs a very large, low-cost parking lot for some big data, are these low-end storage devices a good option?
So be careful when you venture into the land of low-cost storage. Take a hard look at what your storage will be used for — and how it’s going to get fixed when it breaks — before you congratulate yourself for saving a dump truck full of money. Sometimes, the dump truck you know is better than the one you never saw coming until it ran you over.
FreeNAS is a free network attached storage server (NAS server) that is under active development and improving with every release. Though its release number may indicate an alpha/beta product (version 0.7), FreeNAS is stable and can be used on production machines. FreeNAS supports CIFS (Samba), FTP, NFS, rsync, AFP protocols, iSCSI, S.M.A.R.T., local user authentication, and software RAID (0,1,5); all this manageable through an intuitive web-based configuration interface.
We are already a few weeks into 2010, but what’s wrong with looking back over 2009? Below I have collected a number of FreeNAS related posts, howto’s and videos that were posted in 2009. Most of these were found via FreeBSD News, Google News (Alerts) and the Learn FreeNAS blog.
The FreeNAS community and forums are vibrant, full of activity. There are always new users with questions and problems, and experienced users to help out. Others write up useful howto’s and share tips. It is difficult how many FreeNAS users there exactly are, but we can be fairly confident it is quite a number, including corporate enterprises.
Late 2009 Voker Theile, the core FreeNAS developer, announced that further development of the FreeBSD-based FreeNAS would be halted. FreeNAS 0.8 was going to be a Debian-based NAS server. This decision was reverted shortly afterwards, when iXsystems, the sponsor behind the PC-BSD project, offered to sponsor further development of (a FreeBSD based) FreeNAS with Olivier Cochard-Labbé, the founder of the FreeNAS project, returning and assisting with the development. OpenMediaVault is the new Debian-based NAS and developed by Volker, independently from FreeNAS.
A Debian based OpenMediaVault will have better hardware support, but it won’t (as it stands now) be able to include the ZFS file system. Later this year I will write a comparison of the two NAS operating systems

Volker Theile and developers working with him released the following versions in 2009 (in chronological order):
Add TFTP service. It is accessible via ‘Services|TFTP’ in the WebGUI.
Add Samba patch CVE-2008-4314.
Upgrade nano to 2.0.9.
Upgrade PHP to 5.2.8.
Add WOL support for misc NIC’s. Thanks to Tobias Reber for porting WOL patch to FreeBSD 6.4.
Upgrade nfe driver. Thanks to Tobias Reber for backporting FreeBSD 7.0 driver and adding WOL support.
Finally fixed Samba lock file problem (they are located in/var/db/samba now). You can increase the memory filesystem size for /var for LiveCD and’embedded’ installations by modifying the rc.conf variable named ‘varsize’. This is necessary if you are running out of file space for *.tdb files (this normally happens on heavy Samba share usage with many users). The default size
Replace FTP server pure-ftpd 1.0.21 with proftpd 1.3.2rc3. Please note that there can be set additional options via rc.conf variables which are not displayed in the service WebGUI. Please have a look into /etc/rc.d/proftpd script for a detailed list of options.
Add TCP Wrappers. All applications linked against libwrap support this feature, for example services like FTP, TFTP, SSH, NFS… The rules can be configured via WebGUI ‘Network|Hosts’.
Upgrade ATAidle to 2.4.
Upgrade transmission to 1.42.
Upgrade rsync to 3.0.5.
Upgrade cdialog to 1.1.20080316.
Upgrade msmtp to 1.4.17.
Add ability to create a SWAP partition during installation.
Enhance the ‘System|Advanced|Swap’ page to select a file or disk device as swap space.
If you are looking for a good FreeNAS reference book, you may consider buying Gary Sims’Learning FreeNAS: Configure and manage a network attached storage solution book. Packt Publishing has published a few extracts of this book online
That’s it for now. Many links, useful videos and write ups. Do the reading and why not give it a go and build, install and configure your own NAS file server? Doing it yourself saves you a bit of money over buying a NAS appliance, give you hands-on experience and gives true job satisfaction.
Journaled File System or JFS is a 64-bit journaling filesystem created by IBM. It is available as free software under the terms of the GNU General Public License (GPL). There are versions for AIX, eComStation, OS/2 and Linux operating systems. HP-UX has another, different filesystem named JFS that is actually an OEM version of Veritas Software’s VxFS (wikipedia)
Nexenta Systems, the leader in OpenStorage solutions, today announced that 2009 was a breakthrough year for the company. Key milestones for the year included a 740 percent increase in full year revenue from the previous year and an increase in quarterly sales of 630 percent from the last quarter of 2008. The growth reflects the overwhelming global demand for an open alternative to legacy proprietary enterprise storage, particularly in virtualized environments, and Nexenta’s flagship product, NexentaStor, as the product best able to meet this demand.
