VxRail is a fully integrated, preconfigured, and pre-tested VMware hyper-converged infrastructure appliance family based on VMware’s vSphere and Virtual SAN, and EMC software, VxRail delivers an all-in-one IT infrastructure transformation by leveraging a known and proven building block for the Software Defined Data Center (SDDC).
With the power of a whole SAN in just two rack units, they provide a simple, cost effective hyper-converged solution for a wide variety of applications and workloads. VxRail Appliances deliver resiliency, QoS, and centralized management functionality enabling faster, better, and simpler management of consolidated workloads, virtual desktops, business-critical applications, and remote office infrastructure.
Choose from a range of next-gen Intel processors, variable RAM, storage, and cache capacity, and more flexible CPU-to-RAM-to-storage ratios. Single-node scaling and low-cost entry point options allow you to procure just the right amount of storage and compute for today’s requirements and tomorrow’s growth.
A fully populated hybrid appliance supports up to 80 cores and up to 24 TB of raw storage. A 64-node cluster delivers 1,280 cores and 384 TB of raw storage. Additionally, all-flash models available later in 2016 will deliver the industry’s most powerful HCIA to maximize performance and scale for applications that demand low latency.
