Testing results of an Interaction Media Server guest in Hyper-V

Our test host had the following specifications:

Model

HPE ProLiant DL380 Gen10

CPU

2 x Hyperthreaded 20 core Intel Xeon Gold 6138 @ 2.00 GHz (40 physical cores, 40 logical cores, 80 cores total)

RAM

512GB 2RX4 PC4-2666V-R Smart Memory

Storage Controller

HPE Smart Array P408i-a SR

Storage Configuration

System populated with 24 x 600GB 10K SAS HDD (HP Model EG000600JWJNH)

System Drive - 2 drives in RAID 1 (600GB total)

Hyper-V Drive (contains VM's and VHDs) - 22 drives in RAID 10 (6TB total)

NIC

HPE Ethernet 1Gb 4-port 331i Adapter

Network Configuration

1 gigabit interface dedicated to host management; 1 gigabit interface dedicated to the virtual switch for the VM

Operating System

Windows Server 2019 Datacenter 1809 (OS build 17763.737)

We used the following specifications for our virtual machine guest and ensured all required Media Server and CIC configuration had been set as required:

vCPU

8 CPU's with 100% virtual machine reserve (each CPU represents a media engine)

RAM

4GB

VM Generation

2.0

Storage Configuration

300GB fixed size VHDX

Network Configuration

Single interface dedicated from the host, RSS/vRSS enabled

Operation System

Windows Server 2019 Standard 1809 (OS build 17763.737)

Enabled Integration Services
  • Operating system shutdown
  • Time synchronization
  • Data Exchange
  • Heartbeat
  • Backup

Since a virtualized Media Server is capable at best of 32 points-per-media-engine (PPME) with 100% recording, our test machine has the maximum potential call volume of 256 calls (32 PPME x 8 media engines). We ran our test environment at a steady state value of 250 calls with 100% recording for 5000 calls and used an in-house audio scoring program to score all 5000 recordings. Only one recording contained any silence events. The following table shows metrics that we captured during this test:
