My home lab, after having been running XCP-ng on 3 Udoo x86 Ultra "SBC"'s have just been updated to 3 small gamer towers with
The cluster consists of 3 serers with identical specs:
- AMD Ryzen 5 5600G with Radeon Graphics
- ASRock B550 Phantom Gaming 4 motherboard (cheap)
- 2x32 GB 3600 blocks per PC giving my 192GB RAM
- 1 TB SSD as boot drive per host
- 1 TB NVMe as XOSTORE drive per host
- 1 10gbe QNap NIC
Current XCP-ng is 8.2.1 with XO CE.
The RAM is set to 3200 in XMP profile otherwise I get tap device errors in the VMs (aka block I/O errors).
The 1 TB SSD is only used for XCP-ng boot (possibly later on for a few non-critical VMs that I can live without in case of a host crash)
The 1 TB NVMe is setup as thin provisioned XOSTORE (https://xcp-ng.org/forum/topic/5361/xostor-hyperconvergence-preview) - it does not seem slow as such, but comming from 1gbe network and low performing SSD's (<1GB/s) then I have no speed issues ... as of yet. Time will tell
Avg send and receive speed is 1.07GBytes/s according to iperf3 so life is good compared to the now old and retired Udoo x86 Ultra setup
Loving it
