A method and system are disclosed for controlling the storage of data in a storage device to reduce fragmentation. The method may include a controller of a storage device receiving data for storage in non-volatile memory, proactively preventing fragmentation by only writing an amount of sequentially addressed logical groups of data into a main storage area of the storage device, such as multi-level cell (MLC) flash memory, and reactively defragmenting data previously written into the MLC memory when a trigger event is reached. The system may include a storage device with a controller configured to perform the method noted above, where the thresholds for minimum sequential writes into MLC, and for scanning the memory for fragmented data and removing fragmentation by re-writing the fragmented data already in MLC into new MLC blocks, may be fixed or variable.

A storage area network can include a storage virtualization entity—intelligent storage application resource (iSAR)—either as a separate device in the fabric, or as an integrated module in one or more switches within the fabric. All I / O operations can be re-directed to iSAR for processing. iSAR can segment virtual storage and physical storage into units, where each unit of the virtual storage is mapped to a single unit in physical storage. Data associated with incoming I / O operation can be compressed before being stored in physical storage. iSAR includes overflow reserve storage at the block, sub-page and page level to accommodate changes in compressed data size on subsequent I / O operations. These measures can improve I / O performance and reduce fragmentation. iSAR can also employ deduplication of incoming data stored on physical storage to improve storage efficiency.

A method of transmitting time division multiplexed data from a satellite terminal to a satellite wherein the satellite terminal receives a command indicating to transmit data during a frame comprising a plurality of timeslots in accordance with a timeslot reordering scheme. The timeslot reordering scheme is selected to spread data from respective satellite terminals to different timeslots throughout the frames. A processor monitors the use of channels by the satellite terminals, stores bandwidth requests using queues, allocates channels in accordance with bandwidth requests and a bandwidth allocation algorithm, and transmits the channel allocations in a frame. Timeslots not allocated to any of the satellite terminals are contention channels. The number of contention channels changes dynamically, depending on demand for the plurality of channels by the satellite terminals. Queues are provided for each channel for storing high and low priority rate requests and high and low priority volume requests. The bandwidth allocation algorithm determines the preemption of the queues, and allocation priorities.

A system and method enhances performance of a log adapted for use with a storage system. The log is illustratively organized into a plurality of regions, wherein each region comprises one or more entries and wherein each region is allocated to a consistency collection. As used herein, a consistency collection is defined as a set of one or more data containers among which it is desired to maintain transaction consistency, i.e., atomicity of updates of a transaction to those containers. Each entry of the region is adapted to store an update of data from a source, e.g., an application executing on the storage system. Thus, the consistency collection may comprise multiple data containers associated with one or more applications configured to maintain the atomicity of transaction updates to the collection of containers.

A system and method for maintaining a pagefile of a computer system using a technique of reserving portions of the pagefile for related memory pages. Pages near one another in a virtual memory space often store related information and it is therefore beneficial to ensure that they are stored near each other in the pagefile. This increases the speed of reading data out of the pagefile because total seek time of a disk drive that stores the pagefile may decrease when adjacent pages in a virtual memory address space are read back from the disk drive. By implementing a reservation system that allows related pages to be stored adjacent to one another, the efficiency of memory management to of the computer system is increased.

A mechanism to alleviate bandwidth fragmentation in a network employing path computation element(s) to place MPLS Traffic Engineering tunnels. One application is a multiple Autonomous System or multiple area network employing distributed computation of MPLS Traffic Engineering LSPs. A particular path computation element may determine that bandwidth fragmentation is present based on monitoring of path computation failures where desired paths are blocked due to bandwidth constraints. In response to the detected bandwidth fragmentation condition, the path computation element floods a routing notification within its Autonomous System or area. Nodes respond to the routing notification by requesting reoptimization of their own previously requested Traffic Engineering LSPs allowing the path computation element an opportunity to alleviate bandwidth fragmentation.
