Abstract: A storage system creates an abstraction of flash Solid State Device (SSD) media allowing random write operations of arbitrary size by a user while performing large sequential write operations of a uniform size to an SSD array. This reduces the number of random write operations performed in the SSD array and as a result increases performance of the SSD array. A control element determines when blocks from different buffers should be combined together or discarded based on fragmentation and read activity. This optimization scheme increases memory capacity and improves memory utilization and performance.

Abstract: A hardware search structure determines the status of cache lines associated with a large disk array and at the same time reduces the amount of memory space needed for tracking the status. The search structure is configurable in hardware to different cache line sizes and different primary and secondary index sizes. A maintenance feature invalidates state record entries based both on their time stamps and on associated usage statistics.

Abstract: A storage access system provides consistent memory access times for storage media with inconsistent access latency and reduces bottlenecks caused by the variable time delays during memory write operations. Data is written iteratively into multiple different media devices to prevent write operations from blocking all other memory access operations. The multiple copies of the same data then allow subsequent read operations to avoid the media devices currently servicing the write operations. Write operations can be aggregated together to improve the overall write performance to a storage media. A performance index determines how many media devices store the same data. The number of possible concurrent reads varies according to the number of media devices storing the data. Therefore, the performance index provides different selectable Quality of Service (QoS) for data in the storage media.

Abstract: A storage proxy monitors storage access operations. Different address alignments are identified between the storage access operations and data blocks in a storage media. A dominant one of the address alignments is identified. Data blocks are mapped into the storage media to remove the dominant address alignment. An array of counters can be used to track the address alignments for different storage access sizes and the address alignment associated with the highest number of storage access operations is used as the dominant address alignment.
