Actually, pure NVME-based volume will be waste of money. Gluster excells when you have more servers and clients to consume that data. I would choose? LVM cache (NVMEs) + HW RAID10 of SAS 15K disks to cope with the load. At least if you decide to go with more disks for the raids, use several? (not the built-in ones) controllers. @Martin, in order to get a more reliable setup, you will have to either get more servers and switch to distributed-replicated volume(s)...
