Abstract: A multi-tiered cache manager and methods for managing multi-tiered cache are described. Multi-tiered cache manager causes cached data to be initially stored in the RAM elements and selects portions of the cached data stored in the RAM elements to be moved to the flash elements. Each flash element is organized as a plurality of write blocks having a block size and wherein a predefined maximum number of writes is permitted to each write block. The portions of the cached data may be selected based on a maximum write rate calculated from the maximum number of writes allowed for the flash device and a specified lifetime of the cache system.

Abstract: The present invention relates generally to a method for efficient I/O handling in a cluster-based architecture. According to one aspect, the invention enables efficient scheduling of TCP connection migrations within a cluster. According to another aspect, the invention enables I/Os performed as TCP handoff operations to coexist on the same TCP/IP connection with I/Os performed as remote operations.

Abstract: A method and system allows for fast compression and decompressing of data using existing repetitive interleaved patterns within scientific data (floating point, integer, and image). An advantage of the method and system is that it is so fast that it can be used to save time due to a lower amount of data transferred/stored in scenarios like network transfer, disk or memory storage, cache storage or any other real-time applications where time plays a crucial role.
