Abstract
A technique processes input/output (I/O) requests from a set of host computers. The technique utilizes data storage equipment which includes a set of physical storage drives and storage processing circuitry which accesses the set of physical storage drives. The technique involves storing, by the storage processing circuitry, a set of storage drive objects in main memory. The set of storage drive objects includes a set of zeroed chunk tables. Each storage drive object (i) represents a physical storage drive and (ii) includes a zeroed chunk table which identifies storage chunks of that physical storage drive that have been initialized to zero. The technique further involves receiving, by the storage processing circuitry, I/O requests from the set of host computers, and performing, by the storage processing circuitry, I/O tasks in response to the I/O requests. The I/O tasks include zero on demand operations based on the set of zeroed chunk tables.
