Difference between Expressway Small and Medium

[Masahiro Umemoto]

Hi
What is the difference between Expressway Small and Medium?

1)Virtualization for Cisco Expressway
  Small  vCPU:2 vRAM:4GB vDisk:132GB vNIC:2
  Medium vCPU:2 vRAM:6GB vDisk:132GB vNIC:2

2)Capacity(Small and Medium are the same)
  The capacity of one Expressway unit (small and medium-sized virtual machine) is as follows:
  a)Up to a total of 2500 local or proxied SIP registrations on Expressway-C and Mobile and Remote Access (MRA) registrations to Cisco Unified Communications Manager
  b)Up to 100 video calls or 200 audio calls

Does Small have any restrictions?
If there are restrictions, what are the restrictions?

For BE 6000 (M5), Medium Expressway can not be configured.
However, it could be built with BE 6000 (M4).
When updating from BE 6000 (M 4) to BE 6000 (M 5), only Small can be selected, so I would like to know restrictions and notes.

The difference is number of concurrent B2B video calls support, and the type of server it's supported on.

Hi Kris
Thank you for your reply.

Please tell me the difference between Small and Medium B2B call capacity.

Is there no other difference?
ex) Capacity in cluster configuration

Looks like I was mistaken and both small and medium have the same capacity, so it really comes down to which platform you are deploying it one, quite frankly I've always deployed and seen the Medium OVA being used:

●  The capacity of one Expressway unit (small and medium-sized virtual machine) is as follows:

◦   Up to a total of 2500 local or proxied SIP registrations on Expressway-C and Mobile and Remote Access (MRA) registrations to Cisco Unified Communications Manager

◦   Up to 100 video calls or 200 audio calls

Hi Chris

The difference between Small and Medium is described below:
https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab11/collab11/sizing.html#41879

Small OVA can be clustered across multiple Business Edition 6000 nodes for redundancy purposes; however, there is no increased capacity when clustering with Small OVA.

BE 6000 (M4) was able to load Medium, but with BE 6000 (M5) you can not install Medium, so we need to be careful.

P.S.
Sorry for mistaking you for your name
