Abstract: Techniques for improving flash memory flushing are disclosed. In some embodiments, the techniques may be realized as a method for improving flash memory flushing including receiving a request to write to flash memory, writing data associated with the request to the flash memory, identifying a pointer to a region bitmap corresponding to a write region for the write request, marking a bit of the region bitmap corresponding to the request as dirty, and updating the pointer, using a pointer management component, to the region bitmap to contain a dirty block count.

Abstract: Techniques for improving storage journaling are disclosed. In some embodiments, the techniques may be realized as a method for improving storage journaling including recording to a journal a count of valid blocks in a first chunk of storage in flash memory, receiving a request to write a second chunk to the flash memory, determining, using a controller, whether the count of valid blocks in the first chunk is less than a specified threshold, and in the event the number of valid blocks in the first chunk is less than the specified threshold, writing the second chunk to a location of the first chunk of storage in the flash memory.

Abstract: Methods and systems for performing adaptive partitioning of a distributed cache partitioned in cache slices are provided. The slices of the distributed cache are assigned to different computer nodes of the cluster based on a routing table. After a pre-determined period of time, the cache slices can be re-assigned to other computer nodes of the cluster based on access statistics and a new routing table is provided that corresponds to the re-assignment of the cache slices to the computer nodes of the cluster.
