I can confirm that the HP Microserver runs VERY well with Proxmox and NethServer and/or Windows Server or a Windows10.
We have a couple of clients who upgraded their Environment with a new Server, and we chose the HP Microserver G10 after good experience with the Microserver G8 (Which uses an Intel CPU).
We’ve had absolutely NO issues with the AMD CPU. The Windows Server is running an ERP, Antivirus and SQL-Server, but it’s is running really well!
We are using WD Red Disks in the Server and in the Synology NAS (For Backups). The Synology synchs the backups home to whoever keeps the Of-Site backups using CloudStation.
Proxmox can do a (live) backup of the two virtual Windows Disks (C & D, together 300 GB) in about 45 Mins to the NAS. The Windows Server also saves itself using StorageCraft, also this runs extremly fast. The NAS is a small 2-Bay at one of the clients, still, it is powerful enough for it’s duties.
One other thing, more important:
If using virtualization, keep your systems away from RAID5.
Today, with the huge Disks, a disk outage will be covered by RAID5 (in most cases).
However: the Rebuild will usually take a day or more, depending on the disk sizes.
During this time, the one disk carrying parity information will be really heavily used, and becomes itself a candidate for a failure.
Two disks dead, so is your data, and you have to hope for an intact backup!
For virtualization use only RAID1 or RAID10. Proxmox themselves advise on using RAID10 as the most performant.
The HP Microserver (Gen8 or 10) are both very quiet. Two friends are using it as a home server (With Proxmox and Nethserver) and both have the server in the living room.
My 2 cents
