@DustinB3403 i was confirming and adding details to your reply to @Darek-Hamann in the number of hypervisors supported. It can be free, so you mean costly as in windows licensing or performance? If performance, i would hope RDMA would solve that.

@olivier Definitely worth repeating this old post. Oracle has given back so much more than Amazon.

@DustinB3403 StarWinds webpage does not list Citrix, but
StarWind Virtual SAN FREE vs. PAID AUGUST 2018
has a logo for CitrixReady and lists support for KVM and Xen Project VMs.

"Shared storage for KVM, Citrix XenServer and Xen Project VMs (HA iSCSI & CA SMB 3.1.1)" pg 5.

StarWinds free edition specifically mentions HyperV, Xen, KVM, and
vSphere and even supports Remote Direct Memory Access RDMA for serious disk speed up.

Havent convinced management that $6000 for xosan is much less expensive than vmWare. And cannot prove that xosan is faster without much bigger virtual machine allowances in the trial version.
