  • High performance raid mapping
    Patent number: 7111118
    Abstract: An apparatus generally having a plurality of disk drives and a controller is disclosed. Each of the disk drives may have a first region and a second region. The first regions may have a performance parameter faster than the second regions. The controller may be configured to (i) write a plurality of data items in the first regions and (ii) write a plurality of fault tolerance items for the data items in the second regions.
    Type: Grant
    Filed: October 8, 2003
    Date of Patent: September 19, 2006
    Assignee: LSI Logic Corporation
    Inventors: Pramodh K. Mereddy, Lance A. Lesslie
  • System and method for handling shared resource writes arriving via non-maskable interrupts (NMI) in single thread non-mission critical systems with limited memory space
    Patent number: 7003610
    Abstract: A system and method for handling shared resource writes arriving via non-maskable interrupts in single thread non-mission critical system with limited memory space includes a queue for providing temporary storage of a write request. The queue is accessible by lower or higher priority processes for the servicing of the write requests. Upon completion of service to the write requests the system returns control to the standard operations of the single thread system.
