Buying a used VxRail E660: what to check
Verify VMware vSphere and vSAN license assignments, check SAS SSD write endurance in vCenter, confirm 25GbE OCP 3.0 card presence, and ensure matched Platinum power supplies are installed.
FAQ
What is the minimum node count for a VxRail E660 cluster?
Standard clusters require 3 nodes for full vSAN redundancy, while 2-node clusters are supported using a shared witness appliance.
Can the E660 be upgraded to all-flash drives later?
Drive slots support SAS SSDs, but converting a hybrid disk group to an all-flash pool requires reformatting the vSAN disk groups.
