This video demonstrates that the page/block size used in EqualLogic Storage devices are 15MB in size.

In the video, we can see that there are 2 volumes created. The first volume has been created with a size of 1MB, and we can clearly see that it consumes 15MB on the system.

Attempting to modify the volume with any value between 1MB and 15MB results in 15MB being consumed, and once 16MB is chosen as the volume size, the consumed space instantly jumps to 30MB.

Also, we see that any volume size chosen results in the space consumed being a multiple of 15MB, therefore proving the minimum page or block size of 15MB.
