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 three nodes and a maximum of 64. 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 1GbE, 10GbE, and 25GbE 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 25GbE, 10GbE or 1GbE network. 10Gb and 25Gb 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.
