Symon Posted January 31, 2018 Posted January 31, 2018 Hi all I just recently installed unRAID and am still not sure about how to setup my system to get most out of the hardware. I hope somebody can help me with this. I have the following disks setup: Disks HDD: 2 x 6 TB WD Red for Array HDD: 1 x 8 TB WD Red for Array SSD (NVMe): 2 x 512GB M.2 Samsung 960 Pro SSD (normal): 512 GB Samsung 850 PRO 1 x Open slot for additional M.2 SSD available Things I want to run on my Server: 1 X VM as Gaming Computer 5 X VMs Windows Server 2016 (mostly idle) Several Dockers (Plex, Teamspeak, WebServers ...) In my current Setup I use the disks like this: HDD: Created a 12 TB Array 2x SSD (NVMe): Created a Raid 0 for cache which runs all VMs and Dockers on it SSD (normal): used as unassigned device (with the plugin) formated as XFS for the Gaming VM for a second vdisk to store game data (I don't want to backup games and they use a lot of space) Weekly, I automatically back up all VMs and dockers to the array Problem: I feel that since I added the additional SSD as game strorage, the performance of the gaming VM is not as good as it was before. Question: Can unRAID use the potential of NVMe disk for the cache partition as I configured it right now? Do I need to install any special driver or a special configuration for this? I want to reduce the impact of the server VMs and Dockers to the gaming VM as far as it makes sense. If NVMe SSDs in the cache pool dont make sense, I could think of another way for configuration: HDD: 12 TB Array SSD (normal): Use for cache and Dockers 1x SSD (NVMe): Use with passthrough for gaming VM 1x SSD (NVMe): Use with unassigned Devices to run the server VMs (formated as XFS?) The problem with this setup would be how to backup the gaming VM? And the backup would be really big as i need to backup the games as well. As a last option I could think of adding an additional SSD (NVMe) and create a Raid 10 cache together with the normal SSD and run everything on that but I'm worried that the normal SSD would slow down the speed of the NMVe ones. Any help is appreciated Thank you Simon
