Okay what happened with the NAS Server?

Posted on by mdicecca112

I had this question asked earlier today, and the plain answer is “Stuff”.

I decided that I needed more expandability in the server, and since I was using a Fractal Node 804 for a gaming case, I decided to swap out the board and gaming components and put them in the Fractal Node 304.  This allows me up to 8 3.5in HDDs and a lot more real estate.

Couple notes on the Fractal Node 304 Case

  1.  Cable Management is a Pain.  See the bundle of cables by the back of the GPU?  That’s what I mean.  There is only room there because I don’t have the HDD Sliders in.
  2. The PSU design is smart, but is a problem if you need to access it.  Point and case, I didn’t flip the PSU Switch before powering on and had to remove the cover and flip it.

So what am I running in my gaming box and what games do I play?

It’s a rather simple build running Windows 10 to play No Man’s Sky

 

Early NAS Benchmarks

I’m been racking my brain trying to figure out this Synology NAS. I wanted a very simple benchmark, as I don’t need to go into complex workloads.   The problem is that I’m using Synology Hybrid Raid.  From what I can see from mdadm is that Synology created a RAID 5 from two slices of from each 6TB Disk and a RAID 1 from each 3TB Drive, and then RAIDed those two arrays in a RAID6 for 10TB.  It is in interesting way to handle different size disks.

These benchmark speeds are to be expected.  I plan to benchmark the Synology in different RAID Modes as well, but for now, I’ve benchmarked md2 (RAID5), and md1 (RAID1)6
