You can use a single disk or multiple disks for your virtual machine. The total capacity must be at least 64 GiB.
Note:
The partitions size can be larger than the values listed in the following table.
If you are planning to use an antivirus or another approved third-party application, you must add the disk space required by the third-party application to the values in the following table.
Use the following table to refer to the recommended values for disk size and partition:
Note:
A gibibyte (GiB) and a gigabyte (GB) are sometimes used as synonyms, though they do not describe the same output of capacity technically. However, they are close in size. A gibibyte = 10243 and gigabyte = 10003.
The terms mebibyte and megabyte are closely related and often used as synonyms, though they don't technically refer to the same amount of capacity. However, they are close in size, One mebibyte equals 1.048576 megabytes.

Note:
Communication Manager does not support a separate partition for /opt. In the early boot stages, only the root partition '/' is mounted and the Communication Manager code in /opt must be available as a sub-directory of root.
The installer accepts smaller sizes boot partitions.
If a partition is not present then, the parent partition must be larger to include the size of the child partition.
For example, if /var/log/audit is not present then, /var/log must be 25 GiB. If neither /var/log/audit nor /var/log are present then, /var must be 35 GiB.
If the virtual machine has partitions not listed in the above table, for example, /usr or/local, in that case, when determining the disk size, you must add the size of those partitions in addition to the 64 GiB that the Communication Manager requires.
When you configure partitions sizes manually in the Red Had installer, use GiB and MiB units for binary with base 1024.
