jaesii Posted June 18, 2016 Share #1 Posted June 18, 2016 So I've been using XPE for a while now as a SAN for my esxi lab. I have been very unhappy with the performance. My XPE box is loaded up with resources and I can't figure out why the performance is so bad. Its got the following: 1x Intel Xeon L5630 Quad Core W/ HT 16GB ECC DDR3 1066MHz Memory LSI 9211-8i + LSI 9211-4i Intel X520-DA2 Dual port 10 Gigabit network card 5x WD Enterprise Drives 3.5" 2x OCZ Deneva 2 SLC SSDs for R/W cache Both my my esxi servers are directly attached to the xpenology using 10GbE SFP+ Direct Attach Cables I have a Raid5 volume setup as an iSCSI target and here is a screenshot of the performance I get on a Windows 2012 R2 VM I also have a FreeNAS Box that is setup very similar to the Xpenology 1x Intel Xeon L5630 Quad Core W/ HT 16GB ECC DDR3 1066MHz Memory LSI 1068E Raid Controller Intel X520-DA2 Dual port 10 Gigabit network card 6x HGST 1TB 2.5" Consumer drives Here is the same test on the same VM Any reason DSM gives me such bad disk performance?

sbv3000 Posted June 19, 2016 Share #2 Posted June 19, 2016 I've not played with a setup similar to yours, but if were diagnosing I would; Trythe storage as NFS Check the XPE 10gb drivers version and see if there are reported isci issues there is an intel 10gb tuning guide, dont know if it might give you some pointers http://www.intel.com/content/www/us/en/ ... 05811.html Link to comment Share on other sites More sharing options...
