DAS vs. NAS for Unraid and more

Technology Hardware
#1

Hi,

I have a question. I have an option of either:

  1. DAS connected to Optiplex 990 i5-2400 MT with an LSI - external DAS case can hold about 8-10 drives…
  2. NAS using PowerEdge T610 2xXeon E5640 - likely the 3.5 setup for 8 drives

Any thoughts on what would be best route to go? The DAS solution is I guess bigger and better for long term as I can swap a new case, etc… But the NAS all in one is pretty attractive… getting a good price on the PowerEdge so they are comparable in cost. And from what I can tell the T610 with the dual Xeon will be a lot faster than the i5 and has other server oriented things like dual PSU, 2xNic, ECC memory, etc…

Use case is Unraid with docker, etc…

Thoughts?

Thanks!

Is electrical cost a factor?

No. Won’t be an issue really…

I say go for the PowerEdge server then. You can always add a DAS later and you get some server-oriented features.

What area are you from and what are the prices you’re looking at? Frankly I’d say it’s a mistake to buy any 1366 machine for a new system unless you’re in an area with a very limited used market, especially using an old dual socket system as a NAS - it will unnecessarily increase your power costs with little return.

Redundant PSU is largely a moot point without also having at the very least two different circuits feeding them. ECC memory and dual NICs can be had on any other Xeon platform (as well as with some standard Intel Core systems).
You should read through the NAS Killer 4.0, Anniversary 2.0 SNAFU, and OTiS build pages for an idea of hardware recommendations and associated costs based on your use case.

Just NAS duties, NK4 will be cheap, low-power, and effective. NAS+Plex combo, OTiS for quicksync. Heavy compute, lots of VMs - SNAFU will get you the highest core count/performance for the cost without sucking as much power as a 1366 system.

If you must go for a prebuilt rackmount system, I have heard it on the grapevine that there may be some similar but newer systems available at a good price in the near future…

Imma need to hear from from this grapevine.
