The VeloCloud Gateway runs on a standard hypervisor (KVM or VMware ESXi).

Minimum Server Requirements

To run the hypervisor:

  • 10 Intel CPU's at 2.0 Ghz or higher. The CPU must support the AES-NI, SSSE3, SSE4 and RDTSC instruction sets.
  • 20+ GB (16 GB is required for VC Gateway VM memory)
  • 100 GB magnetic or SSD based, persistent disk volume
  • 2 x 1 Gbps (or higher) network interface. The physical NIC card should use the Intel 82599/82599ES chipset (for SR-IOV & DPDK support).

Supported Hypervisor Versions

Hypervisor Supported Versions
VMware ESXi 5.5U3 or later. In order to use SR-IOV, the vCenter and the vSphere Enterprise Plus license are required.
KVM Ubuntu 14.04 LTS and 16.04 LTS

VCG Virtual Hardware Specification

For VMware, the OVA already specifies the minimum virtual hardware specification. For KVM, an example XML file will be provided. The minimum virtual hardware specifications are:

  • 8 vCPUs
  • 8 GB of memory
  • Minimum of 2 vNICs:
    • One vNIC is the public (outside) interface, which must be an untagged interface.
    • One vNIC is the private (inside) interface that must be tagged. This is the interface facing the PE router or L3 switch.
  • Optional vNIC (if a separate management/OAM interface is required)
  • 32 GB of virtual disk

Firewall/NAT Requirements

Note: These requirements apply if the VeloCloud Gateway is deployed behind a Firewall and/or NAT device.
  • The firewall needs to allow outbound traffic from the VeloCloud Gateway to TCP/443 (for communication with VeloCloud Orchestrator).
  • The firewall needs to allow inbound traffic from the Internet to UDP/2426 (VCMP), UDP/4500, and UDP/500. If NAT is not used, then the firewall needs to also allow IP/50 (ESP).
  • If NAT is used, the above ports must be translated to an externally reachable IP address. Both the 1:1 NAT and port translations are supported.
