QNAP TVS-EC1080+ 10-Bay NAS Review

A NAS for the power hungry

There are NASes, and then there are uber-NASes. The QNAP TVS-EC1080+ is one such uber-NAS. Pitched as an enterprise-level unit, the TVS-EC1080+ packs in killer hardware features, as well as a host of applications that s should find useful.

At times, we find that some of QNAP's NAS units can be a bit confusing. Like the TVS-871 that we reviewed not long ago, it's sometimes hard to see the clear lines between enterprise and consumer. There are a lot of features in both units that are clearly targeted toward consumers, although they don't have to be used. If we focus purely on pricing though, the TVS-EC1080+ is definitely a business appliance. At $3,300, we suspect that few home s would consider the TVS-EC1080+, except for the few that feel they must have only the best.

So, what does a $3,300 NAS get you?

THE QNAP TVS-EC1080+

The specifications speak for themselves.

Small- to medium-sized offices would find the TVS-EC1080+ useful, especially with its large capacity and integrated 10GbE . The primary function overall for the TVS-EC1080+ is to serve files, and serve them fast.

In a business environment, most of the software features in the TVS-EC1080+ will not be used. Photo backup, photo serving, torrent ing, and media playback are some of the consumer features available to you out of the box, but we're far more interested in the performance that the TVS-EC1080+ brings to bear.

QNAP designed the TVS-EC1080+ with integrated SSD caching in the form of not just one, but two 128GB mSATA SSDs. Customers are able to install SSDs to four more bays and use them as caching drives for the most performance-demanding usage scenarios.

We configured our TVS-EC1080+ with equally impressive drives from HGST in the form of the Ultrastar He8 8TB helium drives. HGST offers the Ultrastar He8 in both SATA and SAS, but the TVS-EC1080+ only s SATA. The Ultrastar He8 drives are fast and offer copious amounts of capacity, and are perfect for a NAS such as this.

Why didn't we go with "NAS" drives? Well, the Ultrastar He8 drives are designed for environments such as this, as well as rack-mounted applications. Enterprise NAS drives have optimized firmware, high-grade components, longer warranties, and features such as top- and bottom-mounted spindle motors to increase rigidity and decrease vibrations. The Ultrastar He8 drives are no exception.

HGST's use of helium in its drives also decreases internal turbulence and air friction, and the second generation He models deliver the same performance as other drives in their class but with roughly 23 percent decrease in energy use. Businesses using multiple NASes, or racks full of drives will appreciate the power savings over the long run.

We filled all 10 bays with HGST Ultrastar He8 drives for a total raw capacity of 80TB. Any more drives and it would have floated away.

GETTING THINGS UP AND RUNNING

The TVS-EC1080+ is no more difficult to set up and use than any of the other NASes in QNAP's line-up, and it operates much in the same fashion as the TVS-881 we previously reviewed. The following setup portion was taken from our TVS-871 review:

We simply installed the hard drives into their cages, and plugged them in. You're able to configure the storage array via the built-in HDMI interface or by logging in to its web interface. We opted for setup using the web interface, since there's only so much you can do with the two-line built-in display.

Upon and the obligatory istration setup, we immediately configured the TVS-EC1080+ to RAID 6. The system recommended RAID 6 by default, but you're able to choose whatever RAID level you desire. On a NAS like this, there's really no point in using RAID 0, since performance won't be realized over 1Gb Ethernet, and you'll want some sort of redundancy. At our 80TB of total system capacity, RAID 1 would get you 40TB and allow up to four drive failures before complete catastrophe, but halving our total capacity seemed wasteful.

We went with RAID 6 because you get the best combination of performance, redundancy, and capacity. RAID 6 is essentially like RAID 5, but with for double drive failures. With RAID 6 configured, we were left with a total usable capacity of 57.09TB.

Special to the TVS-EC1080+ is onboard SSD caching. The TVS-EC1080+ utilizes two 128GB mSATA drives, in this case from ADATA to act as one 256GB cache volume in RAID 0. Frequently accessed data will be allocated to the SSD volume for faster access. Keep in mind, though, that this is for read operations only. Write operations go directly to disk.

Because we filled up all the drive bays in the TVS-EC1080+ for the array, no drives were left to act as a hot-spare.

Tests

We tested several features of the TVS-EC1080+, including RAID fail, and throughput. We used a 10GbE dual-port NIC from Small Tree for our testbed.

Note that we used four Samsung 850 Pro 1TB in RAID 0 in order to further test the 10GbE performance of the TVS-EC1080+. We also used the Netgear ProSAFE XS708E switch and configured link aggregation to perform our tests over an aggregated link of 20GbE.

Tests were done with the following hardware:

Note: Thanks to CyberPower PC for supplying the Samsung 850 Pro 1TB SSDs!

THE BENCHMARKS:

From the chart above, we see the numbers are thoroughly impressive. There are plenty of usage models that could take advantage of the available performance. Multi- setups are well suited for such high-bandwidth-capable NASes, virtualization, and iSCSI. For attached storage at this performance level, iSCSI becomes an interesting proposition, as it allows you to configure a volume on the NAS as a block-level mount. You're able to format and mount a volume as if it were local storage.

For those who are interested in knowing, the HGST Ultrastar He8 performs irably as well, reaching 207MB/s reads and writes as a single drive. This is largely due to the incredible aerial density that comes with being an 8TB drive. The best part of it is, the He8 is an enterprise drive with respective quality components as well as warranty. Again, we thoroughly recommend you go with enterprise-grade drives.

Comparing our results with QNAP's own tests, which we've verified to be quite accurate, we see that we can get even more performance out of the TVS-EC1080+ with the right kind of setup.

Note: QNAP utilized a RAID 5 array in its benchmarks, which is less taxing than running a RAID 6 array due to the NAS having to compute half the parity. However, RAID 6 can withstand two drive failures while RAID 5 can only take one, and judging from our own RAID 6 vs. RAID 5 benchmarks, the decrease in performance is small enough that we'll gladly take another drive parity.

For those seeking to approach QNAP's benchmarks numbers, you'll more than likely want to use SSD drives. You can attain top speeds too, provided that you have the right network and client station setups. We had to use link aggregation with an appropriate switch.

A beast for SMB or insane home

Like the TVS-871 before it, the TVS-EC1080+ is more than you can ask for in a NAS. Compared to other similarly priced models from competitors, you're getting a lot for your money.

We did encounter a few minor issues while working with QNAP's backup station, though. For example, syncing would at times fail, and while backing up from client PCs, there were times when both Windows and OS X's Time Machine would fail to detect the NAS. Retrying would solve the issue, but it would still happen from time to time.

Where do we see the TVS-EC1080+ fitting into a business? For large-scale enterprises, rack servers are the way, and while SMBS will find the TVS-EC1080+ very powerful, smaller studios will find the NAS incredibly useful as well. Media production studios that are growing beyond single-digit client stations could really benefit from the scalability that the TVS-EC1080+ offers. Large amounts of usable capacity, exceptional performance, and 10GbE allows the TVS-EC1080+ to grow as your business needs grow.

So, where does this leave the home ? Simply put, the TVS-EC1080+ is absolutely overkill for home use. Xeon processers not withstanding, it's incredibly difficult for a home environment to take advantage of the hardware that's inside the TVS-EC1080+. But if you must have an uber-NAS, the TVS-EC1080+ is one such option.
