The vxRAIL is a different approach and i call it "the survivor of the EvoRAIL disaster".
Your vSAN ReadyNode is a certified HW Bundle and you have to put on
- All licensing
- Deployment is putting all pieces together and install Software hand by hand
- Management/FW Update/Uprade Tasks
- (Some kind of easy scale)
vxRAIL
- Complete/Partitial lics included
- Deploeyment 15min (on paper and when the networking guy doesnt have made a mistake)
- One Update package of ESX/DRIVER/FW
- Other nodes need 9min for joining/setup
If you would like to stay at DellEMC you can also take a look to DellEMC XC (Nutanix).
The typical ReadyNode is a 1 or 2U 19" Rack Server in different T-Shirt sizes. I think the Naming scheme is the same for all other Vendors as well.
