The Datrium DVX is a hyperconverged infrastructure (HCI) solution that’s comprised of separate nodes for storage and compute using industry standard server hardware and storage devices. This disaggregated architecture (called “open converged” by the company), improves scaling efficiency and performance over traditional HCIs, similar to some converged architectures.
A Datrium DVX cluster is comprised of one to ten Data Nodes that act as a highly available resource, sharing a pool of capacity with all Compute Nodes in the cluster via 10/25GbE. Each Data Node stores persistent data and handles resiliency functions, with 12 HDDs or SSDs in each 2U chassis. The DVX Disk Data Nodes provide 29TB usable and up to 180TB effective capacity in each chassis, depending on data reduction. The DVX Flash Data Nodes have up to 16TB usable and 96TB effective capacity. Data Nodes have redundant, hot-swappable controllers with mirrored NVRAM, plus redundant power supplies and fans.
DVX Compute Nodes come pre-loaded with VMware vSphere and Datrium DVX Software to provide IO processing and data services, scaling from one to 128 nodes in a cluster. Each Compute Node is a 1U, 16- or 28-Core Intel Xeon server, configurable with up to 768GB RAM and up to 8 SSDs. While the DVX Software is preloaded on DVX Compute Nodes, it installs as a VIB on ESXi. This allows deployments to use any appropriate hardware platform, even re-purpose existing assets, turning them into compute nodes within the overall DVX system. DVX systems allow a “mix and match” of DVX Compute Nodes with third party x86 servers, whether new or already installed in a customer’s environment.
