Single Client Performance - CIFS & iSCSI On Windows

The single client CIFS and iSCSI performance of the ioSafe 1513+ was evaluated on the Windows platforms using Intel NASPT and our standard robocopy benchmark. This was run from one of the virtual machines in our NAS testbed. All data for the robocopy benchmark on the client side was put in a RAM disk (created using OSFMount) to ensure that the client's storage system shortcomings wouldn't affect the benchmark results. It must be noted that all the shares / iSCSI LUNs are created in a RAID-5 volume.

The market doesn't have too many 5-bay NAS units. In fact, the only other 5-bay NAS unit that we have evaluated before is the LaCie 5big NAS Pro from early 2013. That unit was also based on the Intel Atom D2701, but carried only two GbE links instead of the four in the ioSafe 1513+. In terms of encryption support, vendors have two approaches - encrypt a particular shared folder or encrypt the full volume. Synology only supports folder-level encryption in DSM. The graph below shows the single client CIFS performance for standard as well as encrypted shares on Windows.

We created a 250 GB iSCSI target and mapped it on to a Windows VM in our testbed. The same NASPT benchmarks were run and the results are presented below. Note that we also present numbers for the 'Single LUN on RAID' mode which is supposed to provide the best access performance. It does indeed perform better with write workloads, but loses out on read workloads to the standard file-based LUNs.

    ioSafe is the 3rd party backup copy;
    1st onsite, 2nd offsite, 3rd copy on the ioSafe.

    with almost everything digital, the ioSafe is the equivalent of a... safe :) a high quality classic "fire and waterproof" safe will set you back ~$500-600. Add in the cost of the DS513+ and you get where the price comes from...

    if you can backup offsite reliably! then surely do, ioSafe offers an alternative solution, never bad to have other options :)

    Thx jmke. With this particular system (especially setup on HA), it's viable for many SMB's that the 1513+ be used as primary and maybe glacier or another offsite service be used for maybe a smaller set of tier1, hyper critical files. It's possibly the best of all worlds for RPO/RTO, cost, etc. And if a backhoe takes out your internet connection, you haven't lost all DR capabilities.

    Add some layers of kevlar, a spring-mounted cage, and a internal UPS that calls for 5-minutes safe shutdown. Bulletproof, explosion resistant, power outage resistant. Or shove it in a safe for good measure. I bet there is a market for it. If you change the drives to flash ones, you get even better explosion resistancy. Reply

    Where are the grill/swimming pool tests? Reply

    Ganesh, did you check to see if this "disaster-resistant" Synology make-over is also "resistant" to SynoLocker (i.e., patched against it)? Someone encrypting all of my files would certainly qualify as a disaster to me! ;) Reply

    Our review unit came with DSM 5.0 installed, so that is immune to the SynoLocker exploit.

    That said, the lesson from the SynoLocker episode for me was that we might be better off not exposing the unit to the Internet at all. We might end up losing a lot of nice features of DSM, but I think it is worth the peace of mind. In addition, security vulnerabilities exist everywhere. Today, Synology has been exploited - tomorrow, it might be some other NAS vendor.

    I also suspect that the use-case for ioSafe 1513+-like devices involves storing of sensitive data - no IT admin in his right mind would leave ports open from such devices for access from an external network. It would probably be through a VPN or something similar.

    Sadly, I know of some "admins" who do not have the same regard for security. To them, it is just about reacting to the latest request, like "I want to access my files from home and everywhere else". They open it up, and then leave the default basic authentication as-is.

    From experience, I would wager the percentage of those types of admins are a bit higher than you might expect of such a position.

    Something this big would quickly bake if you had it running in a sealed safe. Reply

    Is it also EMP proof? :) Reply
