  • Asymmetric load balancing for RAID storage systems
    Patent number: 8161237
    Abstract: The instant invention broadly contemplates balancing of asymmetric RAID arrays based on application usage patterns. The instantly claimed invention broadly contemplates balancing the type of workload and delivery of the work load in asymmetric RAID arrays by intelligently implementing different types of applications on disks strategically positioned to deliver workload to the RAID channel that is most capable of handling the work load. The invention makes use of the fact that some applications are more large block, sequential transfer dependant while other applications are more small block, high random, high IOP dependent, and places these applications accordingly within the asymmetric RAID array.
    Type: Grant

  • Preservation of hard drive data via dynamic band boundary definition
    Patent number: 7774539
    Abstract: Systems and methods for managing adjacent track interference in a hard drive. An adjacent track interference potential is ascertained in a region of the hard drive, and data corruption is averted via scrubbing data in the region with ascertained adjacent track interference potential, wherein limits of this region are defined.

  • Preservation of hard drive data via preliminary detection of adjacent track interference potential
    Patent number: 7522366
    Abstract: Systems and methods for managing adjacent track interference in a hard drive. Adjacent track interference potential is ascertained in at least one track, and data corruption is averted via scrubbing data in at least one track with ascertained adjacent track interference potential.

  • MULTI-VECTOR ELECTRONIC MAIL
    Publication number: 20080163341
    Abstract: A system includes a processor that separates an email message into a public message component and at least one private message component and memory for storing the public message component and the at least one private message component. The email message includes a public message block having a public message for a plurality of public recipients and at least one private message block having a private message for at least one private message recipient, and the at least one private message recipient is a subset of the plurality of public recipients. The public message component includes the public message from the public message block and the private message includes the public message and the at least one private message from the public message block and the private message block.
