Abstract: A system and method for recognizing data access patterns in large data sets and for preloading a cache based on the recognized patterns is provided. In some embodiments, the method includes receiving a data transaction directed to an address space and recording the data transaction in a first set of counters and in a second set of counters. The first set of counters divides the address space into address ranges of a first size, whereas the second set of counters divides the address space into address ranges of a second size that is different from the first size. One of a storage device or a cache thereof is selected to service the data transaction based on the first set of counters, and data is preloaded into the cache based on the second set of counters.

Abstract: A system and method for managing application performance includes a storage controller including a memory containing machine readable medium comprising machine executable code having stored thereon instructions for performing a method of managing application performance and a processor coupled to the memory. The processor is configured to execute the machine executable code to receive storage requests from a plurality of first applications via a network interface, manage QoS settings for the storage controller and the first applications, and in response to receiving an accelerate command associated with a second application from the first applications, increase a first share of a storage resource allocated to the second application, decrease unlocked second shares of the storage resource of the first applications, and lock the first share. The storage resource is a request queue or a first cache. In some embodiments, the second application is a throughput application or a latency application.

Abstract: Methods and systems for storing data at a storage device of a storage system are provided. The data is first temporarily stored at a first write cache and an input/output request for a persistence storage device used as a second write cache is generated, when an I/O request size including the received data has reached a threshold value. The data from the first cache is transferred to the persistence storage device and a recovery control block with a location of the data stored at the persistence storage device is updated. An entry is added to a linked list that is used to track valid data stored at the persistence storage device and then the data is transferred from the persistence storage device to the storage device of the storage system.
