ESXi + 8GPUs using VT-d - performance impact? - phillips321 - 11-17-2016 So then guys, We're looking at getting a box with 8 GPUs and we're planning on using ESXi on the host and passing through the GPUs to multiple virtual machines.  I've done some quick testing using a single card (AMD R7 240) and i received no performance impact when doing VT-d (yes i know the card is crap but it was used as a PoC) Has anyone here played with running ESXi and passing through the GPUs to a single VM? My reasons for this is that this will be used in a production environment and the ability to snapshot VMs and quickly increase capability is something we're after. What i'm after is any real world experience in particularly any info regarding: Did VT-d cause 8GPUs a significant performance impact? Is there a ceiling limit on PCI devices in ESXi? Thanks in advance RE: ESXi + 8GPUs using VT-d - performance impact? - kiara - 11-17-2016 actualy i think some one did some test with this.. this might help u https://hashcat.net/forum/thread-5522.html
