  • Publication number: 20040128587
    Abstract: A collective storage system and method for restoring data in the system after a failure in the system. The system includes multiple storage nodes that are interconnected by a network and store data as extents. There are also a set of Data Service (DS) agents for managing the extents, a set of Metadata Service (MDS) agents for managing metadata relating to the nodes and the extents, and a Cluster Manager (CM) agent in each node. After a node failure is detected by one of the CM agents, the agents responsible for coordinating the data restoring are notified of the failure. The agents generate a plan to restore the data extents affected by the failure, and then collectively restoring the affected extents based on the generated plan. The coordinating agents might be the MDS agents or DS agents. The failure might be a node failure or a disk failure.

  • Patent number: 6516380
    Abstract: A computer-implemented method and system for accelerating writes to a storage controller by performing log-based sequential write caching of data to be written on a storage device. The data in the log is moved to the storage array later when the system is less active. As a result, random writes are converted to sequential writes. Overall, performance improves since the performance of sequential writes far exceeds that of random writes. A write command containing data is received in a data storage controller, wherein the data storage controller includes a write cache having a sequential log. The data storage controller also includes an index structure indicating the location of data in the sequential log. If the data does not already exist on the log, the data is written to the log contained in the write cache at a location recorded in the index structure.

  • Publication number: 20020165330
    Abstract: This invention relates to a polyolefin copolymer composition produced with a catalyst having a metallocene complex in a single reactor in a process for the polymerization of an &agr;olefin monomer with one or more olefin comonomers, and a molecular weight maximum which occurs in that 50 percent by weight of the composition which has the highest weight percent comonomer content. Preferably, the composition has a comonomer partitioning factor C pf which is equal to or greater than 1.10 or molecular weight partitioning factor M pf which is equal to or greater than 1.15. Preferred composition also have at least 0.01 long chain branches per 1000 carbon atoms along the polymer backbone. These compositions with reverse molecular engineering have superior properties and are easily processable due to the simultaneous presence of the association of high molecular weight with high comonomer content and of long chain branching.
