Dell EMC made some enhancements to its VxRail and VxRack hyperconverged infrastructure (HCI) systems and announced the updates at VMworld this week. VxRail and VxRack are the company’s two primary HCI offerings for customers that are aligned with the VMware stack.

The simplest difference between the two is that VxRail can be purchased as a single appliance and scale out as needed. While VxRack is rack-scale system for larger instantiations, and it also integrates networking natively into the solution. Both VxRail and VxRack use VMware’s vSAN for the software-defined storage component.

Dell EMC VxRail appliances, including the new VxRail G560, will be the first and only HCI appliances jointly developed with VMware to provide integrations that seamlessly work with VMware Cloud Assembly, once it’s generally available. In addition, VxRail appliance updates now will be synchronized within 30 days of new vSAN releases.

Dell EMC also introduced a new version of its VxRack SDDC for building software-defined data centers, and it plans to sync future releases of that with VMware Cloud Foundation software.

According to IDC’s latest converged systems revenue numbers, Dell EMC was the largest supplier in the converged market segment — and the largest hyperconverged infrastructure (HCI) vendor — during the first quarter of 2018. IDC ranks HCI technology providers two ways: by the brand of the hyperconverged product and by the owner of the software providing the core hyperconverged capabilities. While Dell led the branded-box category, VMware was the No. 1 HCI software vendor.

At VMworld on Monday, VMware CEO Pat Gelsinger also announced a tech preview of a new HCI product called Project Dimension. It’s a hyperconverged infrastructure appliance for edge locations running the full VMware Cloud Foundation software stack with NSX SD-WAN by VeloCloud. Dell EMC and Lenovo are the initial hardware partners for Project Dimension. VMware doesn’t yet have a launch date for the edge product.
