Step by Step Comprehensive Detailed Explanation:
A Gatekeeper in PowerMax is a small, dedicated device used for communication between the storage array and Solutions Enabler (SYMCLI), the command-line management interface. The default size of a Gatekeeper on a PowerMax array is3 cylinders.
While the size can technically be specified in kilobytes (KB), the traditional and preferred unit for Gatekeeper size is cylinders. This is because cylinders represent a specific number of blocks on the physical disks, and using cylinders helps ensure consistent sizing across different disk types and configurations.
Why other options are incorrect:
* A. 3 KB, C. 6 KB:These sizes are too small to be practical for a Gatekeeper.
* D. 6 cylinder:While older VMAX models might have used 6 cylinders, the current default for PowerMax is 3 cylinders.
