METHOD AND SYSTEM FOR SCHEDULING I/O OPERATIONS FOR PROCESSING

An operations scheduler and a method of scheduling I/O operations to be processed by a memory drive are disclosed. The method includes receiving I/O operations, and for each one of them determining an estimated processing time, and an estimated processing period indicative of an estimated deadline. The method also includes determining a scheduled order of I/O operations based on the respective estimated deadlines. The method also includes monitoring an actual processing time for the I/O operations and adjusting a virtual time of the operations scheduler if a given actual processing time is above a given estimated processing time of a given I/O operation.
