VxRail nodes are enclosed in a 1-node, single-server system. Each node having one, two, or four multi-core processors and either all-flash solid-state disks (SSDs) or a hybrid mix of flash SSDs and hard drives. The nodes form a networked cluster with a minimum of two nodes or three nodes for scale-out clusters with a maximum of 64 nodes. Nodes within a cluster must be of the same storage configuration, either all hybrid or all flash. The flexibility to mix nodes within a cluster is supported. The first three nodes must have the same compute, memory, and storage configuration, and mixing 1 GbE, 10 GbE, and 25 GbE is not supported. From the minimum configuration to the maximum, the VxRail cluster is easily expanded one node at a time.

System models support either 25 GbE, 10 GbE, or 1 GbE networks. All-flash configurations and environments that will scale to more than eight nodes require 10 GbE and 25 GbE networks. Additional ports are available, allowing the customer to expand VM network traffic.
