virtual machine recommendations for the SBC SWe Lite when running on Microsoft Azure.

Virtual Machine Recommendations for

running in Azure

The recommended hardware and software settings are intended to ensure optimum stability and performance. If the recommended settings are not used, the

Unable to show "metadata-from": No such page "_space_variables"
may not behave as expected. Ribbon does not provide support for SBC SWe Lite instances deployed in non-recommended Azure VMs.

  • Plan enough resources (RAM, CPU, NIC ports, hard disk, etc.) for all virtual machines (VMs) to run in Azure.

  • Allocate each VM with only as much virtual hardware as that VM requires. Provisioning a VM with more resources than it requires can, in some cases, reduce the performance of that VM as well as other virtual machines sharing the same host.

  • The vNIC recommendation is from 2 vNIC to 2 vNIC. See below for guidelines.

Additional Information

  • Minimal networking configuration requires the Management Network Interface and at least one Media Interface to be assigned.
  • Each SBC SWe Lite VM uses approximately 5 GiB of Virtual Hard Drive space. Drive size is predetermined by the imported image.
