Virtualization support for Skype for Business Server 2019

  • Artikel

Skype for Business Server 2019 is supported on virtualization.

While virtualization is supported, there are some key points to remember:

  • Maintain a 1:1 ratio of virtual CPU to physical CPU.
  • Don't move a guest server while it's operating.
  • Migration of a live system and portability of a virtual machine aren't supported.
  • Disable hyper-threading on all hosts.
  • Don't configure dynamic memory on host servers.
  • Use fixed or pass-through disks rather than dynamic disks.
  • Allow for 6-10 percent overhead for hypervisors beyond what the virtual guest requires.

Supported hypervisors

SfB Server 2019 is supported on Windows Server 2016 and Windows Server 2019.

For third-party hypervisors, you need a hypervisor that has passed the Server Virtualization Validation Program (SVVP) testing for the relevant OS. For more information, see Support partners for non-Microsoft hardware virtualization software.
