I came across the Dell VRTX, and as an enclosure that accepts four blades, is apparently relatively quiet, and is perhaps (?) less power hungry than multiple R930/R830 I am really intrigued by it. A VRTX with 4 M830's looks to run about $1200-1300, not counting CPU/memory/storage, so the price is not bad too.
But I noticed that this machine is now about 10 years old and there appears to be no 'updated' version. So, I am really curious about its limitations. For example, the enclosure system board apparently has only a PCI-e 2.0 interface (found this info on a random review website, not the manual). My main interest is in HPC, basically running my own physics codes, which could use fast shared storage, but the VRTX also might be a good candidate to develop and learn MPI, which requires low latency mid- to high-bandwidth networking.
Any opinions on this? Am I getting my hopes up? Is the VRTX old hardware?
Thanks!
