No XCP is installed on a SSD 1tb Sata, the raid would be just for the file server -

vsaad Awesome, thank you! Wanted to make sure that was the case.
Did you install the Management Agent? If so, which did you use?
Personally I've found Citrix's to be the most performant.
-
gsrfan01 The first installation it installed automatically and crashed error IRQ, as it was fresh installation I did a new one without the windows update check and Installed the XCP tools.
Shall I try changing over? just uninstall the xcp tools and put the citrix?
-
I use these, they do require a free login from Citrix: https://fileservice.citrix.com/download/secured/support/article/CTX235403/downloads/citrix-vm-tools-9.2.3.zip
Did you use these? https://github.com/xcp-ng/win-pv-drivers/releases

gsrfan01 Ok great, I will give a go, any tricks or just standard uninstall and install?
Thanks for your attention btw.If anyone else wanna comment regarding the setup I'd appreciate! As it doesn't have gigabit, I may just create a bond with 2-4 eth as well
-
I would uninstall the XCP-NG tools, reboot, then install Citrix's tools, then reboot again.
Then try running something like Crystal Disk Mark against the second drive.
If you don't have GB you'll be limited to pretty much 10MB/s per client even with bonding. Bonding won't increase the speed to a single client, but would let you serve 3 clients at 10MB/s each.
Do you have an extra PCI slot? You could get a GB NIC pretty cheaply.
-
gsrfan01 Okay I'll give it a go.
I also did the crystal mark test, see below:
-
vsaad A PERC-6 is pretty old technology. Getting in the 50 MB/sec I/O range seems pretty good and some of the limitations will be on the disks, themselves. You might try running "iostat -x" while the Crystal Mark test is running to see if anything saturates, like the CPU, or if you get high wait states or other tell-tale signs,
-
vsaad that might be your limit. Those old PERC cards aren't particularly performant unfortunately.
You could try passing the whole device through to the VM: https://forums.lawrencesystems.com/t/xenserver-hard-drive-whole-disk-passthrough-with-xcp-ng/3433
That might help, but I'm not sure if that method still works.
-
gsrfan01 Not sure that was ever officially supported, though I did implement a direct connection to a VM on XenServer with better results than with the standard process. You're right, it may or may not work with much newer versions of XCP-NG/XS/CH.
