Virtual machine requirements for Interaction Media Server

Requirement area	Specifications
Guest operating system	Microsoft Windows Server 2016 Microsoft Windows Server 2019 Azure VMs tested using Windows 2016 Data Center
Virtual machine vCPUs	Maximum of 8 cores assigned to each Interaction Media Server guest. If more than 8 cores are needed to achieve the target call volume, create more virtual machines instead of adding more vCPU’s to the guest. Important! Interaction Media Server requires 100% CPU reservation in the guest VM.
Networking	Network - The Interaction Media Server guest VM requires a fully-dedicated network. Network Interface Card (NIC) - The Interaction Media Server guest VM requires a fully-dedicated physical network interface. Virtual Network Switch - The Interaction Media Server guest VM requires a dedicated Virtual Network Switch. RSS/vRSS - Use RSS/vRSS to distribute network communications over multiple network interfaces. For Azure deployments, use Accelerated Networking feature on any Media Server VM. Accelerated networking enables single root I/O virtualization (SR-IOV) to a VM, greatly improving its networking performance. This high-performance path bypasses the host from the datapath, reducing latency, jitter, and CPU utilization, for use with the most demanding network workloads on supported VM types. Important! Network traffic must not delay the transmission and receipt of RTP packets or you may experience audio issues.
Virtual RAM	Minimum of 4GB Azure Media Servers tested using 14GB RAM
Bandwidth usage	The Network Sent utilization of the Interaction Media Server guest VM must not exceed 120 Mbps. Consult the documentation of your hypervisor for methods of determining bandwidth usage.
Scaling VM's	It is recommended to scale out by adding more virtual machines.
Guest antivirus	Note: See http://testlab.genesys.com for the latest information on approved antivirus products for Interaction Media Server.
