Choosing virtual disk size

To choose the size of the virtual disk:

Find out the following data:
- The average daily volume of email traffic in your organization.
- The percentage of email messages that end up in Backup.
- The required storage duration for messages in Backup.
Multiply these values.
For example, an organization's email traffic is 30 GB per day, 30% of messages end up in Backup, and you want to keep messages for 30 days.

30 GB • 30 days • 0.3 = 270 GB.
Divide this figure by the number of nodes in the cluster. The result is the Backup volume you need on a single node.
For example, suppose the infrastructure of Kaspersky Secure Mail Gateway has 4 nodes.

270 GB / 4 = 67.5 GB
In the table below, in the 'Backup' row, determine the closest suitable volume, then trace that column to the table header to find the corresponding value of the virtual disk volume.
In our example, the suitable Backup volume is 80 GB, which corresponds to a 300 GB virtual disk.

If the table does not include the volume you need, please contact Kaspersky Technical Support.

In the web interface of the Kaspersky Secure Mail Gateway application, specify the maximum size of the Backup, quarantines and event log according to the data from the table corresponding to your virtual disk size on a single node.

The Syslog partition and the MTA queue are fixed in size and cannot be modified.
