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.

    Most modern safes have a small hole in the back for cabling, which is usually intended to bring electricity into the safe to power humidity control equipment (and that is usually just a heater). When you are forced to place a safe in a location that is not climate controlled it's pretty important to prevent condensation from occurring anywhere inside.

    I've never looked into the impact that hole has on fire protection (I presume there is some impact) but obviously flooding is an issue unless you spay foam it or use some sort of grommet.

    Cannon, for example, provides power and a cat 5 connection on most of their safes. It's not a problem. Reply

    I doubt the floor of my flat is rated to half a ton of spot weight. Nor that of most SOHO offices in houses or houses converted to office buildings (as with a lot of small town businesses).

    It's a pretty practical solution, though, I'll grant you, if your floor is rated for it.

    Engineers have another word for power supplied into perfectly insulated boxes - "ovens" :)
    Great for baking bread, not so good for computers.

    Plus, if it gets hot enough inside, it'll actually cause the insulation to kickoff prematurely rendering the safe useless in a fire. It's a non-trivial balance between heat produced during normal operation and heat resistance during a fire event. DIY and proceed with caution.

    Nice review! I certainly don't think I could roll my own one of these!

    I had a question about some of the time scales you present in the misc/concluding remarks section.

    Have you considered testing/reporting RAID1 or RAID10 rebuild times? Or are they so much (and consistently so) faster than the RAID5 times that it isn't particularly interesting?

    How does a device like this ensure good thermal transfer such that the hard drives don't overheat under regular use, while still giving good thermal isolation so they don't melt in the event of a fire? Reply

    well they have active cooling, check the cooling fans. In case of fire you can see that white stuff "DataCast Insulation" will keep the heat of the fire under control, converting to gas (and thereby taking up the heat)

    I tested the smaller brother (ioSafe 214) with fire and water and filmed it.

    others have put them in cars , houses, etc and the drives survive.

    During normal operation the active cooling keeps the drive well within the safe limits.
    If you want to enjoy data disaster recovery service make sure that you take HDDs from the qualified lists.

    you can also just launch up Ubuntu and mount the Synology drives like this to copy your data.
    ideal would be a second unit to just plug and play the drives...

    Folks, a normal DS1513+ diskless on Amazon is $780. This is $1600, more than twice the amount. For this price I would invest in a true DR solution that mirrored a normal DS1513+ to a cloud service like S3 or Glacier, or even another DS1513+ offsite. The latest Synology DSM supports all of the above and the strategy covers ALL disasters, natural or otherwise. Reply

    This is a 5 bay device, which is usually configured in a RAID5 equivalent. With 4-6TB drives, that's 16-24TB capacity. Finding a cloud provider and Internet uplink capable of transferring that amount of data in a reasonable timeframe is not trivial. Reply
  • robb.moore - Thursday, August 14, 2014 - link

    You're right in the mark Gigaplex. With this unit, 90TB is possible with 2 expansion bays. For people concerned about recovering quickly, it can take months (maybe a year?) to stream 90TB back. And for many cloud providers, they might offer to ship a single HDD back but not an entire array.
