VxRail nodes are enclosed in a one-node, single-server system, with each node having one or two multi-core processors and either all-flash solid-state disks (SSDs) or a hybrid mix of flash SSDs and hard disk drives (HDDs). 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 network. 10 Gb and 25 Gb Ethernet networks are required for all-flash configurations and environments that will scale to more than eight nodes. Additional ports are available, allowing the customer to expand VM-network traffic.
