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

@olivierlambert absolutely true.
I have 3 servers at home each with 1 NVMe disk, so ... I choose 3, also because 3 is the usual minimum for minimum fault tolerance and recovery in a cluster... and it provides direct disk access for the VM vs running diskless on one of the servers during/after migration eg after applying updates to the cluster etc.

I don't mind testing things and since I'm new to XCP-ng (not Xen) and enjoy tinkering as I'm a Linux Systems Administrator by trade so I'm enjoying it, even though the version I'm running is a beta. I don't have the money for my 3 nodes to run the full paid version of either XCP-ng or XOSTOR ... so I'm tinkering away even with limits

So far though, home vs enterprise, then I'm not really seeing anything special besides FC SAN usage on VMWare vs what I have available at home that is a main difference for switching, though I think Ceph is the better way to go vs xostor for enterprises. The reason I choose XCP-ng over Proxmox to run at home was the general enterprise feel and prior Xen knowledge I have and that it is a type-1 hypervisor vs the Proxmox that is type-2... and the GUI feels better and less cluttered and a lot more responsive in XCP-ng.

@olivierlambert It's just 3 small black cheap CXC2 towers - nothing special - all LEDs are disabled so they are not interesting at all (as you can see)
