The GUI at times made things more complicated than other NASes. One example is the storage nomenclature. Infortrend calls "pool" what most other manufacturers call "volumes". And "volumes" in Infortrend-speak are what most other manufacturers call "iSCSI targets".

Setting up a RAID 10 volume, uh pool, is another example. RAID 10 is actually a nested combination of RAID 0 and 1, i.e. a stripe of two mirrored arrays. While every other manufacturer we've seen to date makes RAID 10 creation a simple button on a volume creation screen, Infortrend makes you first create a two-disk RAID 1 pool. Once that is created, you expand the pool to add another two-disk RAID 1 block. Once done, you have a RAID 10 volume/pool. There is no wizard to guide you through this, by the way, you have to refer to the User Manual.

Another good example of unnecessary complication is joining the NAS to an Active Directory (AD). I've read the section on AD three times now and I'm still confused. A big part of the section is devoted to creating an additional primary forward lookup DNS zone in AD for the NAS. This configuration starts on page 81 of the User Guide if you'd like to take a look and see if I'm missing something.

Another annoyance we ran into was setting folder permissions for encrypted folders. You can't create an encrypted folder via the Folder> Share > Add function. The Create Shared Folder > Options screen lists all other folder options, but not encryption. But when you create an Encrypted folder using the Folder > Encryption screen, it doesn't automatically share that folder, or even provide access to the option on the Edit screen.

The only way we found to share an encrypted folder was to use the Explorer function, as shown in the screenshot below. This is something Infortrend should fix, since it is really unnecessarily complicated and not documented.

Overall, the admin interface for the EonNAS Pro 500 has some very useful features for the business user. It's just a little complicated to set up and understand at times, especially compared to better-known brands in this market segment like Synology and QNAP.

To get a better feel for the interface, check out the online demo (email registration required). The gallery below also provides additional screenshots of some of the features.


We tested the Pro 500 with version 1.4.55 firmware, using our NAS test process with RAID 0, 5 and 10 volumes. As is our standard practice, four drives were configured in each volume type.

As we've found with other products, there is a marked difference between Windows File Copy and Intel NASPT File Copy results. The benchmark summary below shows relatively consistent Windows File Copy results for RAID 0, 5 and 10 volumes, respectively measuring 69, 66, 72 MB/s write and 72, 71 and 65 MB/s read.

Intel NASPT File Copy results were much lower across the board, coming in at 37, 34 and 35 MB/s write and 49, 53 and 42 MB/s read for RAID 0, 5 and 10 volumes.

iSCSI performance of 60 MB/s for write and 51 MB/s for read ranks the Pro 500 at or near the bottom for iSCSI throughput for D525 Atom-based NASes. Only the aging Thecus N5200XXX did worse than the Infortrend for iSCSI write with 35 MB/s. All other tested D525 NASes had iSCSI writes of 80 MBs and higher. The performance gap for iSCSI read wasn't as great, with the next best Thecus N4200PRO starting at 59 MB/s, topping out at 79 MB/s for the same Thecus N5200XXX that did so poorly on writes.

We wanted to run attached backup tests, which the Pro 500 OS supports. But the Pro 500's logs don't log backup events, so we couldn't accurately time them. Same goes for network backup—no logged events for that either. The lack of backup event logging is an odd omission for a NAS that claims to be so business focused. We hope Infortrend adds the capability in a future OS release.
