The following table displays the minimum supported profile values for different IP Office virtual machine roles in primary and secondary servers:

1. If there is any profile misalignment between the user and channel quantities, use the highest-profile that meets all requirements.

2. More than 250 recording channels with Media Manager requires approximately 12 vCPU or 30 GHz CPU cycles in total.

3. Each one-X Portal client connection counts as one load.

4. The CPU values shown apply to all virtualization platforms. However, for Hyper-V the CPU values should be increased by 20%.

5. If Media Manager is enabled, add 250MB RAM and increase the typical IOPS values.

6. Typical IOPS is the average HDD I/O transactions per second during normal operation. When backup, intense logging or Media Manager are in use, more IOPS are required; 40 to 200 IOPS depending on backup data size, logging rate or recording channels.

7. Voicemail Pro requires 0.5 MB per minute for messages, prompts and announcements. Each user and group mailbox is limited to up to 30 MB (1 hour).

8. Media Manager requires 60 KB per minute for non-authenticated VRL files and 120 KB per minute for authenticated VRLA files. Media Manager also reserves 1 GB of space for the call details database and other operations. Note that more than 250 channels of recording requires at least 12 vCPUs and 30 GHz CPU cycles.

9. The quoted AWS machines instances are recommendations only. The range of machine instances and the capabilities of existing instances change frequently. Therefore, other instances can be used so long as their capabilities match the profiling resource requirements.

10. To achieve the stated capacity and performance, you must provision all IP Office virtual disks as Thick Provision Eager Zeroed or the equivalent for the particular hosting platform.
