I recently got my VMWare ESXi cluster up and running. 3 Dell Poweredge r710 rack servers running VMWare ESXi 6.5. The storage is presented via Dell MD1000 DAS attached to another r710 via SAS cable. The DAS server is connected to all three ESXi hosts via SFP+ cables connected to Mellanox ConnectX-2 NICs. This blog is actually hosted in a resource pool in this cluster!
