Question

A customer wants to reduce the performance impact incremental SAN Copy (ISC) has on their source LUN. They plan to use a clone between the current source and destination LUNs, and then use the fractured clone as the new ISC source LUN. The source LUN performs two hundred 4 KB random I/O per second, with a 1:1 read/write ratio. The source LUN is 768 GB in size, and the clone will be fractured for five minutes. How much data will be copied to the destination LUN?
