Overview
Provides recommended disk-space requirements for Cisco ISE VMs in production environments, detailing minimum, maximum, and optimal allocations for different deployment types.
This table provides the recommended Cisco ISE disk-space allocation for running a VM in a production deployment.
To boot a GPT partition with 2 TB or more, change the firmware from BIOS to EFI in the VM settings boot mode.
