vSAN is a software-defined storage product that is sold as an option with VMware’s vSphere hypervisor, providing the storage virtualization layer for a Hyperconverged Infrastructure (HCI) cluster built on vSphere. VMware partners with server OEMs to create separate HCI products, including the Dell EMC VxRail, Lenovo ThinkAgile VX and Hitachi Vantara UCP HC, each of which is covered in Evaluator Group’s HCI Comparison Matrix and associated documents.
In addition to those vendor-branded products, vSAN is also the foundation for Ready Nodes, HCI appliances that are offered by over a dozen infrastructure vendors. This Product Brief will focus on Ready Nodes.
Ready Nodes are based on VMware vSAN, vSphere and vCenter unified management. This stack runs on x86-based server hardware provided by a number of different vendors, and also AMD’s EPYC CPUs. These companies sell the solution as their own HCI appliance products, each certified by VMware.
There are well over 100 Ready Node models available from approved vendors (most listed below) in various hybrid and all-flash configurations. See current datasheets from each vendor to determine which Ready Node configurations or “profiles” they currently support.
