I need to replace a six year old Dell Poweredge T620 server. I was thinking about replacing it with another Poweredge T630, with this CPU: Intel® Xeon® E5-2630 v4 2.2GHz,25M Cache,8.0 GT/s QPI,Turbo,HT,10C/20T (85W) Max Mem 2133MHz. I want to use Hyper-V but I'm not sure if I should use RAID or if there really is a big enough performance advantage for the extra cost. I was thinking about going RAID10 using the PERC H730 RAID Controller with 1GB NV Cache but is that a good idea to have the VHDX and host all on the same RAID10?
Would there be performance problems if I just had two stand alone SSDs? One would have the host Windows Server 2019 and the VMs would be on the second SSD. I understand that the speed difference between stand along drives and RAID10 (with 4 drives) is 4 times faster the read and 2 times the write. But with the SSDs being so fast now, is it necessary to go with RAID10 for a small office? I will be running an Active Directory/Application VM and a Remote Desktop VM. There are a total of 15 users and 5 of them will occasional work on the Remote Desktop VM. Thanks in advance for any and all suggestions, recommendations and criticisms!
