  • OBJECT STORAGE SYSTEM
    Publication number: 20140244929
    Abstract: The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. Logical storage volumes are created from a logical storage container having an address space that maps to storage locations of the physical data storage units. Each of the logical storage volumes so created has an address space that maps to the address space of the logical storage container. A logical storage container may span more than one storage system and logical storage volumes of different customers can be provisioned from the same logical storage container with appropriate security settings.

  • Method of balancing workloads in object storage system
    Patent number: 8769174
    Abstract: The storage system exports logical storage volumes that are provisioned as storage objects. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. When traffic through a particular protocol endpoint is busy, the logical storage volume undergoes a rebind process pursuant to which the logical storage volume is bound to a new protocol endpoint, and the binding to the old protocol endpoint is removed upon completion of all pending input-output commands issued through the old protocol endpoint.

  • Configuring Object Storage System for Input/Output Operations
    Publication number: 20140181398
    Abstract: A method processes input-output commands (IOs) in a storage system. The storage system receives an IO including first and second identifiers. The first identifier is used to direct the IO to the storage system. At the storage system, the method retrieves the second identifier from the IO and translates the second identifier to a logical storage volume identifier. Then, the method executes the IO on storage locations referenced by a logical storage volume corresponding to the logical storage volume identifier.

    Publication number: 20140104606
    Abstract: A nanoporous gold disk (NPGD) as a novel surface-enhanced Raman spectroscopy (SERS) substrate. NPGD has SERS enhancement factor similar to that of gold nanoshells, but allows, for example, at least three times more benzenethiol molecules to be attached to its surface due to large surface-to-volume ratio. The high capacity enables the rapid detection of attomole-level benzenethiol molecules with relatively high detector temperatures. Additionally, a fabrication process to make NPGD with controlled size and highly reproducible SERS activities.

  • Virtual machine snapshotting in object storage system
    Patent number: 8677085
    Abstract: The storage system exports logical storage volumes that are provisioned as storage objects within logical storage containers. These storage objects are accessed on demand by connected computer systems using standard protocols, such as SCSI and NFS, through logical endpoints for the protocol traffic that are configured in the storage system. A snapshot profile can be separately defined for each of these logical storage volumes, even for those that are within the same storage container. The snapshot profile for a logical storage volume defines whether or not snapshot is enabled for that logical storage volume, the frequency of the snapshot, and the number of snapshots to be retained.
