摘要： System and method for dynamic storage tiering are disclosed. A storage hot-spot in a first storage pool is detected. A first point-in-time copy of a virtual volume including the storage hot-spot is created in a second storage pool according to the detecting. Write requests directed to the virtual volume are redirected to the second storage pool. When decreased I/O activity directed to the storage hot-spot in the second storage pool is detected, the point-in-time copy in the second storage pool is reintegrated into at least one of a second point-in-time copy or the virtual volume.

摘要： A method for validating data in a data storage system comprising associating a first data chunk with first check data and storing the first data chunk and the first check data on a first storage device. Additional associated data chunks of the first data and associated additional check data are stored on at least one of the first storage device or one or more additional storage devices. At least a portion of the first check data and at least a portion of the additional check data are stored to a second storage device, which is distinct from the first storage device and the additional storage devices. I/O access to the second storage device is minimized by retaining at least a portion of the first check data and at least a portion of the additional check data in a readily accessible storage medium, during servicing of a first I/O request.

摘要： A magnetic field concentration means and method for use in conjunction with an implanted device responsive to an externally generated magnetic field. More specifically, a magnetic field concentrator is disclosed which includes a metallic slug located between a magnetic field generator and a magnetic pick-up coil contained in the implanted device. The metallic slug concentrates magnetic lines of flux at the pick-up coil. In a specific embodiment, the implanted device is an intracranial pressure monitoring device (ICPM) which is located within an orifice formed in a recipient's skull. The magnetic field concentrator is positioned within the orifice and directly above the ICPM, thereby concentrating magnetic flux lines at the ICPM. Two configurations of the slug are disclosed, one being in the form of a cylinder and the other being in the form of a truncated cone. In another application of the concentrator, a bandage or other suitable holding means positions the slug externally to the implanted device, thereby again concentrating magnetic lines of flux at the implanted device.

摘要： Methods and structure for automated determination and reconfiguration of the size of a cache memory in a storage system. Features and aspects hereof generate historical information regarding frequency of hits on cache lines in the cache memory. The history maintained is then analyzed to determine a desired cache memory size. The historical information regarding cache memory usage may be communicated to a user who may then direct the storage system to reconfigure its cache memory to a desired cache memory size. In other embodiments, the storage system may automatically determine the desired cache memory size and reconfigure its cache memory. The method may be performed automatically periodically, and/or in response to a user's request, and/or in response to detecting thrashing caused by least recently used (LRU) cache replacement algorithms in the storage system.

摘要： A system and method for managing computer applications running among computing systems based on determined risk of resource saturation is disclosed. In one embodiment, a volatility of resource usage for each computing system is computed based on computed resource usage gains/losses associated with each computing system. A current resource usage of each computing system is then determined. Further, a risk of resource saturation is determined by comparing the computed volatility of resource usage with the determined current resource usage of each computing system. The computer applications running among the computing systems are then managed using the determined risk of resource saturation associated with each computing system.

摘要： The invention provides a system, apparatus and procedure whereby a controller manages computer access to a number of storage volumes in a storage peripheral. To accomplish this, a system administrator assigns a plurality of port IDs to a disk array controller, the disk array controller being responsive to requests from a computer using any of the plurality of port IDs. Next, the system administrator configures a data structure in a memory of the controller such that at least a subset of the plurality of port IDs are mapped to particular ones of the number of storage volumes. Next, in response to an access request by a computer, wherein the access request specifies a target port ID, the controller grants the computer access to only those storage volumes whose mapped port ID corresponds to the target ID.

摘要： A data volume rebuilder reduces the time required to reconstruct lost data in a RAID protected data volume operating with a failed physical disk drive. A data volume rebuilder uses the remaining functioning physical disk drives in the RAID protected data volume operating with the failed disk to regenerate the lost data and populate a virtual hot spare store allocated in a separate RAID protected data volume. The recovered data is distributed across the physical disk drives supporting the virtual hot spare store. Once the virtual hot spare store is populated, the data volume can recover from a subsequent failure of a second physical disk drive in either RAID group. After replacement of the failed physical disk drive, the data volume rebuilder moves the recovered data from the virtual hot spare store to the new physical disk drive.
