not sure if its a practice, but given the large amount of 1st Generation Xeon E5s that came on the market last year (and they would have been 4-5 years old out of those DCs) and also the large amount of Dell C6100 servers that also arrived on the market (I have one in house that came out of Yahoo) my guestimate would be around the 4-5 year mark... but, again, just a guess...

Some of those servers are fantastic value when you get them from a ex-stock supplier. I was seeing 8 thread and 64gb ram boxes for ~£125. If you are building a dummy cloud these are great to play around with.

  yea, the c6100 i got has 8 xeons (4 nodes) 48gb RAM (4x12) and cost about £300 quid... we got some for the office (64gb per node) and they where about £600... given what you are getting, cant complain!

    Out of interest, did you encounter any driver issues? I was warned by a few people saying that some of these servers are designed for the client and therefore have non-standard NIC's and finding drivers could be a problem. I've not encountered this and found Windows, Linux and BSD (FreeNAS) all run from standard installs.

      have Windows Server 2016 running on them currently, and no problems. worked out of the box. not tried any other OS, so cant say about those...

  If you can snag westmere socket boards for E5/E7 hold on to them. The old westmere E5/E7 socket upgrade CPU's from 3rd parties are dirt cheap literally ~$120 for a 10/20 thread xeon. Sure it's still a first gen so no AVX, AVX2, AES, etc. But it is still a lot of compute power. The issue is a 4-8 socket CPU board to fit them in will run you ~$3000.

    Those old 20 thread xeons DRINK power. I wouldn't recommend them unless you're getting your energy for free. (Though there is no such thing as a free lunch.)

      the Westmere E7s seem to be the equivalint of the Xeon X5600 series[1]... so, between 105 and 130w... sticking 4 or 8 of those in a box will blow most power budgets!

  Hmm. I wonder when all the Tesla P100 GPU servers being sold now will get dumped on the market... Does GPU-compute server hardware obsolesce faster or slower than standard CPU-compute hardware?

    I do remember seeing older (not sure the generation) NVidia CUDA gear going cheap... when i seen it, it was about 5 year old... so, possibly the same... maybe less...
