Depending on resource reservation, the following variants are available to configure Avaya SBC:
SBC: Resource reservation equivalent to standalone Avaya SBC 310 model.
Small SBC: Resource reservation equivalent to standalone Avaya SBC 310 model.
EMS: Resource reservation required for running only EMS.

Storage reservation |
Thin provisioned is recommended. Minimum storage required is 64GB. If you want to keep more logs and backup files, you can use the ISO storage type over OVA. The default value is 64 GB with OVA storage.
Note:
Larger disk space impacts the performance.

Thin provisioned is recommended. Minimum storage required is 64GB. If you want to keep more logs and backup files, then recommend to define more disk storage maximum of 160 GB. The default value is 64 GB.

Network Interfaces |
6 Virtual Interfaces |
4 Virtual Interfaces |
2 Virtual Interfaces |
Note:
If the ESXi host does not have the minimum resources to allocate to the virtual machine, the virtual machine will not start.
To reach the capacity requirements, the allocated or available bandwidth must match the session capacity expected as required for VOIP traffic with audio or video based on the codec used.
If the CPU clock speed on a system is lower than the 2.2 GHz minimum requirement, based on the customer hardware clock speed, reservations must be increased to reach the reservation range of 8800 MHz to 9600 MHz for SBC and 6600 MHz to 7200 MHz for EMS. If the system has a higher clock speed, a minimum of four cores must be allocated even though the total CPU reservation (four times the hardware clock speed) is above the range mentioned. If these requirements are not followed, the system may not function as expected and might have system interruption.
You can run Avaya SBC in SBC+EMS mode or SBC only mode. You can only combine SBC+EMS when you have a single machine (hardware or virtual) with no HA. That is, a small or medium configuration. A small or medium non-HA configuration requires only one 4-vCPU core with 8 GB of RAM for both SBC and EMS functions. For an HA pair, you need to separate the SBC function from EMS. The SBC HA pair must have two 4-vCPU cores and 8 GB of RAM. The EMS must have one 3-vCPU core and 8 GB of RAM.
