Could you please share the complete specs of your Xenifer and Xenifer2 Servers.
From the excellent video you made, I was only able to get that it is a R710 from Dell (purchased from Server Monkey) and that it has Dual CPU x5670 at 2.93Ghz. It also has 2 Intel 240GB SSDs, Dual 850W power supplies, it has the 8x2.5" disk configuration. It has 32GB of RAM (which you later updated to 40GB)
But, what RAID card do you use? Do we need any type of RAID config if we use it for XCP-NG such as you have done with your Server and the 2 Intel 240GB SSDs?
Thanks for your reply and for always sharing your best practices and knowledge!
