Hi everyone,
I have a CMS question related to capacity planning.
Example Design for Reference:
Site A:
x1 CMS1K C220 M6 (Call Bridge + Database)
Site B:
x1 CMS1K C220 M6 (Call Bridge + Database)
x1 Database Only Node (Installed on separate hardware)
I do not plan to enable call bridge grouping due to the additional peer-to-peer routing complexity.
That being said, per the virtualization documentation : https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/virtualization-cisco-meeting-server.html
The formula for HD Ports (720p) is : 4 vCPU + (1 vCPU per 1.25 HD ports) & 1GB RAM per vCPU
The CMS1k's shipped with a CMS VM configured with only 8vCPUs and 16GB RAM
The CMS1k's have a total of 48 vCPUs and 255GB RAM.
It seems a bit odd to me that Cisco would build the default VM like this, but I guess it’s because they don't assume anyone’s deployment scenario. I can just imagine someone using the default VM and not utilizing the server to its full HD port capacity.
Is my calculation correct below?
48vCPUs and 48 GB RAM is roughly 55 HD Ports (720p video participants)
Should I max out the CMS1K and apply all the CPU to the one Call Bridge VM?
I want to get as many concurrent calls as possible.
