When deploying the OVA, ensure your environment meets these minimum requirements for Version 14: Hypervisor : VMware ESXi 6.7 U2 (minimum) or 7.0 U1/U2/U3. VM Hardware : Minimum Hardware Version 13. : CentOS 7 (64-bit). Sizing Guidelines Small (150-1,000 users) : 2 vCPU, 4–6 GB vRAM, 80 GB vDisk. Large (7,500-10,000 users) : 2–4 vCPU, 8 GB vRAM, 110 GB vDisk. Essential Documentation ("Useful Paper") The disk partitioning and kernel requirements changed

An file is a single package containing the virtual machine configuration (OVF) and the virtual disk images (VMDKs).
