Abstract:
Technologies are provided for integrating a caching module into a data storage system architecture. A request to perform an I/O operation is received at the caching module from an initiator. The caching module provides a notification to a storage driver that the request will be delivered to the storage driver in the future. The storage driver then determines whether the request can be satisfied. If the storage driver determines that it will be able to satisfy the I/O request, the storage driver can optimize the allocation and placement of the I/O request before receiving the actual I/O request. When the caching module subsequently sends the actual I/O request to the storage driver, the storage driver utilizes the previously allocated space and optimized placement to perform the requested I/O operation.
