-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am looking to use Xen on my workstation and am thinking of 32-64 GB ram. Is it really that important to use ECC ram? How often will the non-ecc ram crash my system? Also I've heard about FS corruption and the need to use ZFS. My machine will not be on 24/7 and I can tolerate a restart once per week, but I care a lot about data integrity and my file system. I will be running around 10 PV Linux DomU's and some 1-2 Windows HVM's.(most likely will passthrough a GPU to the one of them). I still haven't decided on what hardware should I get. Perhaps someone around here with more experience can help. Things I need: IOMMU(fully working one) PCI-E slots - 4+(running many Video cards) RAM - ECC? - 4-8 Slots 32GB-64GB CPU - 8 Core AMD 3Ghz+ or 4-6 Core Intel 3Ghz+(sub 600 $) TPM header matters but it's not a necessity So far I've come up with the following AMD: AMD 8320 + Asrock 990FX Extreme9 Says it supports 64GB with 4 slots Yet on the supported memory list - only modules of 8 GB are listed, so I am not sure if it can really use 16GB ones. Also I am interested if it can use ECC ones. Intel: Intel i7-4770 Asrock Z97 Extreme4 Now I am sure this one can only go 32 GB Non-ecc, also the Vt-d support is not really official. Intel i7-4930k Asrock X79 Extreme6 6 cores, Official Vt-d support and 8 slots. Yet still no ECC. Intel Xeon E5-1650V2 Asrcok EPC602D8A Now this is a bit expensive, yet it's finally a server grade stuff I guess, also it has 6 cores and ECC ram of course. Intel XEON E3-1241V3 Asrock EPC602D8A Expensive as well. Only 4 cores. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJTqdUDAAoJEMqHhflCh8gXQOEQAJsblhjYBjsmEMdmrGc9XvOp 7UgbURjvqCW1u8rjtwGwVgLFny1wTW2BjXoYlKBlv9jzEG7iCZIh31xbpS0KepE9 SNAFkuXNMT/lWju30etZqWJpL6xNJcd8elod+A9Y3TQvQpHh9nQWy3mhbxRYNBYO vHdLaS6mjvRBTit8fqBWxHgtJfs2PwcX9R4C2dE1k/sOwrL7jDgPX2xeTr/kjQOl isXjWIhxIRf2qhKFzfR/RnNIh1XiBs8WwvJqVeHthxHbe3Ziw7D059k/neu12aq5 zqCJ2uTSUYuTQYnQKniNewJyQ7uWqqaH+BLCpekGStx/rBTulMNDi6PEeU52hGem keo9TPVBYmXKOmJi5/k21iJaYc9zwZLEVzhkkb0+Yb+hXoX1AEiiIhd8sgmusVZw /Y6jK3nk46cebLi7/8rZ/cTFvZvritYt84Q6WND86CGoFMumoLFi950sC/cp03hA BqZuOVUWdYCcKTdPbjTJv4u/AMZX0oNmDmYl2HDLeeIxOMKzecIoEcs5be6ydCsB yITsrnDoNViWI9yRjFs1J3DmqObJTV2+ObuAfmHe/t94/Zq5DjWa1nf0+0F1o3Qp hkxW26rID4B1z/0sYv3/xJ9vs8PDXOI3TnmPwbWzDRuSAHTBUWyEbkfXOlGKSYQW 5tywfhhin+D72yau0rDX =2uQp -----END PGP SIGNATURE-----
