摘要： A controller interrupts and restarts writing data from a buffer memory to a medium and prevents buffer underrun errors. The controller includes an address memory for storing a recording medium address or a buffer memory address, which indicate the location of the data when the interruption occurred. A synchronizing circuit sequentially reads data from the recording medium and data from the buffer memory prior to the interruption while synchronizing the written data and the stored data. A restart circuit restarts writing data when the recording medium address or the buffer memory address matches the address stored in the address memory.

摘要： A method and system for improving data migration from source data stripes to destination stripes in a Redundant Array of Independent Drives (RAID) logical drive migration (LDM). The invention describes a procedure for checkpointing data migrations, so that if the system should fail in the middle of the LDM, the computer can resume the LDM from the last checkpointed destination stripes, thus ensuring accurate tracking of data location. Further, the invention also provides the capability of properly checkpointing a data write to a stripe according to whether or not the stripe unit has been migrated previously.

摘要： A method for maximizing buffer usage in a disk drive system. Control circuitry within the disk drive system tansfers the defective sector list for the disk to a buffer, and places the list in a reserved list area. The size of the defective sector list is then determined and the reserved list area is reduced to a size equal to the size of the defective sector list plus some spare room. If the newly sized reserved list area is not at one end of the buffer, it is then moved to one end of the buffer to leave the remainder of the buffer as a contiguous and expanded reserved user area for use data. The expanded reserved user area reduces the time of read or write operations in a disk drive.

摘要： A method and apparatus for enabling a magnetic disk storage device that stores data according to a first data structure characterized by a fixed-length disk block size to respond to input/output requests from a host that define data according to a different data structure characterized by a different fixed-length host block size. A host adapter transfers requests and data between the host and a cache memory in the magnetic disk storage device as host blocks. A disk adapter transfers requests and data between the cache memory and magnetic disks as disk blocks. CRC data and a sector number are appended to each host block in a set of disk blocks.

摘要： A busy disk evaluation system includes a busy disk evaluation module and a control module. The busy disk evaluation module is configured to perform a busy disk evaluation operation in which it processes access request statistics relating to access requests directed to a server, the server including a plurality of disk storage units, respective access requests requesting access to respective ones of the disk storage units, to identify which, if any of the disk storage units is busy. The busy disk evaluation module is configured to determine whether a disk storage unit is busy in relation to a ratio between the number of access requests requesting access to the disk storage unit per unit time exceeds a selected access request per unit time threshold in relation to a total number of access requests and a selected ratio threshold. The control module is configured to control the busy disk evaluation module. In that operation, the control module is configured to provide the busy disk evaluation module with the selected ratio threshold.

摘要： An electronic system and method that maintains time dependencies and ordering constraints in an electronic system. A timing controller utilizes a representative bit to track timing dependencies associated with information and ensures the information is communicated and processed in an order that preserves the timing dependencies as the information is converted from parallel to parallel or parallel to serial operations. The present invention tracks the order in which information is loaded in a electronic hardware component and ensures that the information loaded into the electronic hardware component at a particular time is processed without interruption by information loaded at a different time. For example, the timing controller tracks the order in which texel information associated with a pixels parallelly loaded in a staging memory and issues electronic signals that cause the information loaded at a particular time to sequentially empty without interruption by information parallelly loaded in the staging memory at a different time.
