May 7, 20215 yr Hi! I've embarked on a major upgrade of my UnRAID machine and am looking to optimise and reuse various SSDs. My goal is: - array (all in hand) - Windows VM (ditto) - OS X VM combined with a RAID 0 scratch drive - various dockers (all in hand) I have a 1TB NVMe SSD that is currently set up as a single cache drive and is currently utilised for the Windows VM and a couple of dockers. I would like to dedicate this SSD to the Windows VM. Not clear if cache or passthrough is the best approach. I plan to repurpose: - another 1TB NVMe SSD. I would like to dedicate this to the OS X VM. - a pair of 250GB NVMe SSDs. I would like to set these as a dedicated RAID0 array for use as a scratch drive for the OS X VM. Seems sensible to use this RAID0 array as the cache too although if this pair need to be dedicated/passed through(?) to the OS X VM, I could use the docker's SSD for cache. - a 512GB NVMe SSD. I would like to dedicate this to various dockers. I have a Threadripper supporting PCI 4. The Windows VM's SSD is PCI 4. The remaining SSDs are PCI3 which I plan to use in an Asus Hyper M.2 X16 to make use of the available PCI lanes on the processor. I'm not 100% clear on cache pool configuration or passing through/dedicating NVMe drives to VMs so would appreciate some pointers. Thanks! BD.
