Going into this article, I had high hopes of blistering performance with the Infortrend EonNAS Pro 510 loaded with SSDs and an amazing amount of data compression that would make this combination a viable solution for holding massive amounts of data. We didn't achieve either of those goals, but we did manage to reduce the amount of data sent to the array with dedupe and compression enabled.
On the performance side, we found that the Intel Atom processor is a bit underpowered for what we asked it to do. We observed the CPU at 100% utilization with the compression features enabled. Even without compression enabled, we saw a few instances of 100% or near 100% utilization and that helps explain why the EonNAS Pro 510 lags behind other 5-bay NAS products including Thecus units with older firmware that still has the ZFS option.
The deduplication feature does work on the EonNAS Pro 510, although we didn't achieve the same results Pure Storage talks about in its marketing material. This really isn't a big surprise since consumer and enterprise data is quite a bit different.
For this test, I went with real-world consumer data even though the compression levels would have increased significantly with other file types. Also, the more data you add to the NAS, the higher the deduplication level.
It should also be noted that the Pure Storage systems are insanely expensive compared to the EonNAS Pro 510. It's around $10 per GB compared to the EonNAS Pro 510 that's around $530 for the NAS, $500 for five Western Digital Red 2TB HDDs, so roughly $10 per TB.
At this time, Infortrend is the only NAS manufacturer that we know of that offers deduplication in a SMB NAS at this price point. It's a nice feature to have, but the type of data you store on the NAS determines its effectiveness.
