Modern hard drives are remarkably reliable devices, but most have an average uncorrectable read error rate of 10^14. Statistically, that means one read failure for every 12TB of data. The drive doesn’t “crash”; it just gives you corrupted data every now and then.
The key to maintaining a consistently high level of data integrity is found in the ZFS file system employed in the EonNAS Pro series. ZFS features an extensive hierarchical checksum strategy, which eliminates what is often called “silent” data corruption with self-healing storage algorithms. Operating way down at the file system level, ZFS attacks data rot where it starts, at the bit, byte, and block level.
Benchmarkreviews.com have done some thorough testing and written it up in a 15 page review of the EonNAS Pro 850X NAS Server which uses ZFS. Overall they were very happy with the product and rated it 9.3 out of 10, though they were not compare the EonNAS Pro 850X NAS Server with similar NAS server.
The review concludes with:
The EonNAS Pro 850X is targeted to a well-established class of NAS users, the business community. What they’ve done with their latest round of products is to bring high-end nformation assurance features down to their base models. Very large data centers know from experience that some piece of data stored in their facility gets corrupted about every 15 minutes. That’s the sort of thing that kept people awake at night, until they found a solution. Sun built the ZFS file system into their Unix-based operating system in 2005, and now it’s one of the stars in the EonNAS product.
The other thing that kept CIOs and IT Directors up at night was the exponential growth of non-structured data, most commonly, email. Once again, ZFS comes to the rescue, with deduplication capability that was incorporated in 2009. ZFS is also very good at managing snapshots, being both quick and space-efficient. Given all of these benefits, you might wonder why every NAS doesn’t use ZFS. One of the reasons may be that porting ZFS to Linux means having to comply with BOTH the GNU General Public License, and the Sun CDDL, which isn’t currently possible. Almost every NAS I’ve tested to date ran a custom Linux distro; the EonNAS models are the only ones to run Solaris 11, a derivative of the original SunOS that pioneered ZFS. So, while the functionality and features of the EonNAS Pro 850X are strictly limited to its intended business role, they are extremely advanced and Infortrend is pioneering the use of high-end data integrity tools in the low end of the marketplace.
