Supported and Unsupported Hosts, Configurations, and Environments for OVA Demo Clusters in ESXi and vSphere

To help you make the correct decision for your organization's technology needs, we offer a demonstration version of Qumulo Core with limited support from the Qumulo Care Team.


  • VMware ESXi or VMware vSphere 7 (or higher)
  • The latest Qumulo Core OVA (a VM file compatible with ESXi and other virtualization products)


To learn Qumulo Core's interface and explore its API, you can launch a virtual Qumulo Cluster from anywhere using VMware Desktop or VMWare Fusion with our OVA. We would like you to experience the Qumulo API by testing scripts and developing software using a virtual cluster.

To evaluate Qumulo Core's user experience and features, including cluster upgrades, adding nodes to an existing cluster, and more, you can import the same VMWare Desktop OVA into a VMware ESXi or vSphere environment for non-production use

Below are the requirements for using an OVA cluster with VMware ESXi or vSphere, including the requirements for the limited support that we currently offer for free, non-production, virtual demonstration clusters.  

Supported Environments, Hosts, and Requirements

ESXi Host with One of the Following Processors

  • Intel Xeon E5-1620 to E5-1680 V2 series (or newer)
  • Intel Xeon E5-26xx V2 (or newer)
  • Intel Xeon E5-48xx V4 series
  • Intel Xeon E7 V2 through V4 series processors
  • Intel Xeon Scalable Processors (Gold or better)

ESXi Host Memory

12GB of RAM Minimum

  • 4 GB of RAM for ESXi
  • 8 GB recommended (4GB minimum) per Virtual Qumulo Node in a four-node cluster

Virtual Networking

  • Standard vSwitch (Virtual Switch) from VMWare
  • A single VMXNET3 Virtual Network Card per Virtual Node
  • IPv4 and IPv6 link-local for forming a Virtual Cluster
    • You can isolate IPv6 to a single ESXi host.

Backing Storage

  • Any Qumulo Cluster, over NFS
  • Local Host Storage of two or more SATA III drives in RAID 0, RAID5, or better


  • SSDs are recommended but aren't required.
  • You can deploy Qumulo OVAs on vSphere using the vmware web-client (vca) option. The vpxclient option is unsupported.  

Unsupported Configurations, VMWare Features, and Environments

  • Cloning a deployed VM after the VM powers on  
    • Qumulo Core encodes the MAC address that the node first booted with and doesn't discover other nodes that have the same mac address encoded in their configurations. 
  • Virtual Hardware configuration changes to Virtual Nodes
  • Virtual Clusters that:
    • Span hosts
    • Run Virtual Nodes on more than one host
  • VMotion (Compute or Storage) for running Virtual Nodes or Virtual Clusters
  • VMware hardware passthrough technologies for VMDirectPath I/O passthrough devices


  • Occasionally, there are changes to virtual machines, disk images, and volumes that might prevent an upgrade from one version of Qumulo Core to the next in a virtual environment.
  • For evaluation purposes, other storage configurations might be functional but unsupported.
