SAN concepts

A 200-GB LUN is created in an empty 500-GB volume whose volume guarantee option is set to Volume. LUN reservation is enabled, fractional reserve is set to 100, and scheduled snapshots are disabled. Immediately after the LUN is created, what is the maximum free space available in the volume?

Explanation

A space-reserved LUN in a volume with a volume guarantee has space equal to its LUN size set aside when it is created, preventing other volume objects from using that capacity. Therefore, the 200-GB LUN reserves 200 GB of the 500-GB volume, leaving 300 GB free. A 100% fractional reserve provides overwrite protection for reserved objects rather than consuming a second LUN-sized allocation immediately.
