We are going to set up a new server to host our VM's. We use Hyper-v and will be using Windows server 2019. The host we have are not clustered. They are set up with the OS on the same hard drive partition are the VMs and configure Raid 6. This server will replace an older one. It will host 6 vm's one of which is a Domain Controller. The new server will be a HP Proliant DL380 Gen10 with 128 GB of RAM and 2 TB of usable space.
How it be better to put the OS on it's own hard drive? If so, should I set the OS hard drive to Raid 1? VM's Hard drive to Raid 5 or 6? This server is located local. I check the drive lights weekly. At what point do I need to up the number of NICs we use? The host servers have 4, we use 2.
Please let me know if you need additional info.
