When the Tenable Appliance VM is initially deployed, it provides a total of approximately 30 GB of usable disk space by default. This is in part to provide a smaller initial download size. However, when using SecurityCenter in most environments you will want to increase the virtual disk size as the data collected will quickly fill the available space. Please refer to the SecurityCenter documentation or contact Tenable Support for guidelines to adequate disk space allocation.
Once the available disk capacity is over 60 GB the disk capacity notification area will not be displayed.
