The Dell Validated Design for Retail Edge with Deep North is based on three sizing options, depending on workload needs and HA requirements. A small configuration consists of a single PowerEdge (XR11 or XR12) with VMware vSphere 7.0. This deployment provides the necessary hardware to run a single Deep North GPU virtual machine (VM) without HA. A medium configuration includes dual PowerEdge (R650 or R750XA) servers with vSphere 7.0, while a large configuration consists of a three-node Dell VxRail E660F. Both medium and large configurations provide the necessary redundancy to offer a highly available processing environment. A small configuration, while not providing fully redundant HA, does offer the ability to create backups of video footage and configuration details using vSphere snapshots and clones. These methods are discussed here, along with the fully redundant HA capabilities provided in medium and large configurations. See the System Design chapter for a complete list of components and the Bill of Materials for hardware specifications. For vSphere documentation, see the VMware vSphere Documentation.
