Note: I recently purchased a Synology DiskStation DS411j & I’m putting up posts about things I figure out. This is part of that series.

I’m making this its own post because so much other tweaking of your Synology DiskStation requires that you know the CPU. It’s not hard to get this info, but having it readily available is nice.

Find out the CPU your DiskStation is using by checking out What kind of CPU does my NAS have on the Synology wiki. In my case, the DS411j uses a Marvell Kirkwood mv6281 1.2Ghz ARM1.

While you’re at it, it’s a good idea to know if your CPU is 32- or 64-bit. To get that, enter this on the command line:

uname -m

In my case, I got this back:


On my Mac, I get this:


My Mac is 64-bit (hence the x86_64), while my Synology DiskStation is 32-bit. If you don’t see x86_64 in your results, you’re using a 32-bit CPU.

  1. If you use this command:

    cat /proc/cpuinfo

    You’ll get these results:

    Processor: Feroceon 88FR131 rev 1 (v5l)

    Feroceon? What the heck is a Feroceon? Well, I poked around, & according to this page, the Feroceon 88FR131 is another name for the Marvell Kirkwood mv6281.
