    摘要: Methods and apparatus for cut-through cache memory management in write command processing on a mirrored virtual volume of a virtualized storage system, the virtual volume comprising a plurality of physical storage devices coupled with the storage system. Features and aspects hereof within the storage system provide for receipt of a write command and associated write data from an attached host. Using a cut-through cache technique, the write data is stored in a cache memory and transmitted to a first of the plurality of storage devices as the write data is stored in the cache memory thus eliminating one read-back of the write data for transfer to a first physical storage device. Following receipt of the write data and storage in the cache memory, the write data is transmitted from the cache memory to the other physical storage devices.

    摘要: A system, method and computer program product for accessing host data records stored in a virtual tape storage (VTS) system. The computer program product includes a computer readable storage medium having computer readable program code embodied therewith. The computer readable program code includes computer readable program code configured to receive a mount request to access at least one host data record in a VTS system; computer readable program code configured to determine a starting logical block ID (SLBID) corresponding to the at least one requested host data record; computer readable program code configured to determine a physical block ID (PBID) that corresponds to the SLBID; computer readable program code configured to access a physical block on a magnetic tape medium corresponding to the PBID; and computer readable program code configured to output at least the physical block without outputting an entire logical volume that the physical block is stored to.

    摘要: A method and system for cache optimization in a hybrid solid state drive and magnetic storage cache architecture for a content delivery network (CDN) is disclosed. The CDN has a number of geographically distributed points of presence (POPs) across the Internet. Customers of the CDN pay for storage of content objects. Cache management in a POP analyzes information related to content objects to determine if storage will be on a solid state drive (SSD) instead of a magnetic drive. The information used in this analysis is from the application layer or above in the open systems interconnection (OSI) model. The content objects are delivered from either the SSD or magnetic storage to end users.

    摘要: The present invention measures an actual utilization frequency of data and controls a location of this data in a storage apparatus in a case where a host computer makes joint use of a storage apparatus and a cache apparatus. A portion of data used by an application program 1A is stored in a storage apparatus 2 and a cache apparatus 3. A management apparatus 4 detects an I/O load of a page (4A), and detects an I/O load of cache data (4B). The management apparatus 4 determines a corresponding relationship between the page and the cache data (4C), and adds the I/O load of the cache data to the I/O load of the page.
