Table 1 lists the hardware requirements.

Table 1: Minimum Hardware Requirements for VMware (Junos OS Release 17.4 to 18.4)

Description

Value

Number of cores

Note: Performance mode is the default mode and the minimum value is based on one port.

For performance mode: Minimum of 4

  • 1 for VCP

  • 3 for VFP

Note: To calculate the optimal number of vCPUs needed by VFP for performance mode:

  • Without CoS—(2.5 * number-of-ports) + 3

  • With CoS—(3.5 * number-of-ports) + 3

For lite mode: Minimum of 3

  • 1 for VCP

  • 2 for VFP

Note: If you want to use lite mode when you are running with more than 3 vCPUs for the VFP, you must explicitly configure lite mode.

Memory

Note: Performance mode is the default mode.

For performance mode:

  • Minimum of 5 GB

    1 GB for VCP

    4 GB for VFP

  • Recommended of 16 GB

    4 GB for VCP

    12 GB for VFP

For lite mode: Minimum of 3 GB

  • 1 GB for VCP

  • 2 GB for VFP

Storage

Local or NAS

Each vMX instance requires 30 GB of disk storage

Minimum storage requirements:

  • 40 GB for VCP

  • 4 GB for VFP

vNICs

  • SR-IOV

    Note: SR-IOV is only supported with Intel Ivy Bridge CPU (or higher) and Intel x520 NICs using ixgbe driver or X710 NICs with 10G ports and using i40e driver. Any other NIC models are not supported.

    Support for ixgbe driver and i40e driver is available from Junos OS Release 18.4R1 onwards.

  • VMXNET3

Note: See Virtual Network Interfaces for vMX for an overview on the types of virtual network interfaces supported by vMX.
