Use the DCE sizing guide to determine the hardware resources necessary for a virtual appliance to monitor a given number of device nodes.
Note: VMware ESXi versions older than 6.7 support fault tolerance on virtual machines with 1 CPU only. Please refer to your vendor's documentation for more information about fault tolerance.
The disk space required to monitor a given number of nodes varies according to the device types monitored and the amount of data you want to store.
In DCE 7.9.3 and newer, the minimum hard disk size is 40GB, increased from 18GB in the previous versions.
To determine whether to add another hard disk, you can view available disk space in the "Storage Settings" display, accessed from the Server Administration Settings option in the System menu. View this display periodically to help determine how quickly the virtual appliance consumes disk space.
Note: To store large amounts of surveillance data, using a remote repository is recommended.
