Hi,
i want to build a Server but im facing basic questions. Its about improving the current system and/or maybe i have to rethink the whole concept
Setup:
E3-1245V5 with integrated P530 graphic
32 Gb ECC Ram
512Gb NMVE Disk
2x4 Tb WD Red for Storage
MSI 236A Mainboard onboard
Nvidia 1070
Additional USB3.0 PCIE Card
Additional Intel GBIT CT Card
My aim is to do the following
- Win10 for gaming, CAD - Solid Works, Lightroom [storage on OMV, network bandwith ...]
- Openmediavault for Storage
- Kodi - using Ubuntu as OS
- Arch as the host OS
Maybe that sound crazy. But at the moment i have here 3 PCs doing the things i wrote. But they are quite old.
- Win10 runs with the help of this forum. Thanks again! I created a partition on my fast NVME disk. This partition is only for Win10.
- i created Hugepages with 26 Gb for later use of the VMs
- because my additional Networkcard is together with different other things in one group i decided to add the onboard Networkcard to vfio. I would like to use the onboard Card only for Openmediavault to get a better network performance

[ 3639.951607] vfio_ecap_init: 0000:01:00.0 hiding ecap 0x19@0x900- i build a software raid with my host system, not inside the VM. So i added the /dev/md0 to the OMV OS
So this is what i get
- the networkperformance is horrible. Using iperf i get about 95 MBit/s. I think it should be something near 900. Inside the VM OMV says it its connected to GBit
- I cant do anything like SMART monitoring inside the VM. Is there a way to do this? Thats a nice to have
- I have a quad code with HT. What would the best way to distribute the CPU power? I said to myself, 3+3HT would be good for Win10. Kodi and OMV can share. Or how does KVM work. Lets say Kodi and OMV arent active. Will the Win10 installation grab as much CPU as possible even if i attach e.g. 2+2HT
- The SSD inside Win10 iss horrible slow. somewhere near 1 mb/s [4k]. Is there a way to improve this. Would it be faster to use a cow file?
- how to prevent Arch, or dumb me, to touch a file system that is attached to a VM. What happens if i would write accidently data to the raid while the VM writes data at the same time?
Finally here is my config of the Win 10 installation
