Overview of VxRail scale-out rules
When you deploy a VxRail cluster, the first three nodes need to be identical models—for example, a VxRail cluster with three E660 nodes. If the hardware resources (for example, memory, storage capacity, network uplinks, and so on) are not enough for the virtual machines (VMs) running in the VxRail cluster, you can scale up or scale out the VxRail cluster. If you scale out the VxRail cluster, you need to consider the following VxRail scale-out rules:
- All nodes in a VxRail cluster must run the same version of VxRail software—for example, VxRail Manager, VMware vSphere, hardware, firmware, Ethernet driver, or host bus adapter (HBA) driver. VxRail appliances have a lot more components, and all of them should/would be identical.
- All-Flash or Non-Volatile Memory Express (NVMe) nodes cannot be mixed in a VxRail hybrid cluster.
- All VxRail G-Series nodes must be identical in their configuration in a chassis.
- 10 GB and 1 GB...
