Managing accesses to storage objects

摘要

A method is used in managing accesses to storage objects. Access I/Os being directed to at least one storage object are received into a first queue that operates on a first in first out basis. In accordance with the first in first out basis, a batch of the access I/Os is created from the first queue. The batch is transferred to a second queue that is controlled by ordering logic. The batch in the second queue is ordered in accordance with the ordering logic. All of the access I/Os from the second queue are processed in order, before any additional access I/Os are added to the second queue.

1. A method for use in managing accesses to storage objects, the method comprising:
receiving access I/Os directed to at least one storage object into a first queue, wherein the first queue operates on a first in first out basis; in accordance with the first in first out basis of the first queue, creating a batch of the access I/Os from head of the first queue, wherein the number of the access I/Os in the batch is based on characteristics of the at least one storage object; transferring the batch of the access I/Os from the first queue to a second queue that is controlled by ordering logic; ordering the batch in the second queue in accordance with the ordering logic, wherein the ordering logic orders the access I/Os in the batch by logical volume and logical block address; and processing all of the access I/Os from the second queue in order, before adding any additional access I/Os from the first queue to the second queue.
