摘要： A method of operating a storage controller that receives data access requests containing a logical block address and a count of blocks involved in the access request. A record is generated and persistently stored indicating whether particular logical block addresses have been accessed since creation. The persistent record is subsequently accessed to enable selected operations to be skipped or aborted when they selected operations involve logical block addresses that have never been accessed.

摘要： A new and improved apparatus and method for rebuilding a replacement disk of a fault tolerant, mass storage drive array subsystem of a computer system. The method calls for a microprocessor to check a stripe for consistency. If the stripe is inconsistent, the microprocessor rebuilds a predetermined number of stripes. If the checked stripe is consistent, then the microprocessor checks a next stripe and repeats the above-described process. Because the drive array subsystem receives both system requests and rebuild requests, the present invention allows a user to select the drive array subsystem's priority in processing system requests versus rebuild requests, thereby allowing greater system access to the drive array subsystem during peak times of system requests.

摘要： A system for performing on-line reconfiguration of a disk array in which a source logical volume is reconfigured to a destination logical volume. Disk array configuration is invoked if a new physical drive is inserted, or a drive is removed. Reconfiguration can also be performed if the user desires to change the configuration of a particular logical volume, such as its stripe size. The disk array reconfiguration is run as a background task by firmware on a disk controller board. The reconfigure task first moves data from the source logical volume to a posting memory such as RAM memory. The reconfigure task operates one stripe at a time, with the stripe size being that of the destination logical volume. Once a stripe of data is moved into the posting memory, it is written back to corresponding locations in the destination logical volume. The reconfigure task continues until all data in the source logical volume have been moved into the destination logical volume. While the reconfigure task is working on a particular logical volume, data remains accessible to host write and read requests.

摘要： Storage controllers and related methods of operation are described. One method tracks storage access operations to a logical disk. The method persistently identifies storage blocks that have been accessed. Responsive to the identifying, the method selectively skips subsequent operations to storage blocks that have not been accessed.

摘要： A method and apparatus which indicates the physical location of one or more peripheral devices. A system operator uses an input device to select an icon that is displayed on a display device. The icon represents a single peripheral device or a group of peripheral devices among a plurality of peripheral devices. For example, an icon may represent a disk drive, a group of disk drives disposed within a storage unit, an array of disk drives, an array of disk drives disposed within one or more storage units, etc. After the system operator selects the icon, an indicator light associated with each of the one or more peripheral devices represented by the icon illuminates to identify the physical location of the selected peripheral device or devices. Other peripheral devices are contemplated, such as a bank of modems, floppy drives, CD-ROM drives, etc.

摘要： A single read request to a memory controller generates multiple read actions along with XOR/DATUM manipulation of that read data. Fewer memory transfers are required to accomplish a RAID5/DATUM parity update. This allows for higher system performance when memory bandwidth is the limiting system component. In implementation, a read buffer with XOR capability is tightly coupled to a memory controller. New parity does not need to be stored in the controller's memory. Instead, a memory read initiates multiple reads from memory based on an address decode. The data from the reads are multiplied and XOR'd before being returned to the requestor. In the case of a PCI-X requestor, this occurs as a split-completion.
摘要翻译：对存储器控制器的单个读取请求产生多个读取操作以及该读取数据的XOR / DATUM操作。需要更少的内存传输来完成RAID 5 / DATUM奇偶校验更新。当存储器带宽是限制系统组件时，这允许更高的系统性能。在实现中，具有XOR能力的读缓冲器与存储器控制器紧密耦合。新奇偶校验不需要存储在控制器的存储器中。相反，存储器读取基于地址解码来从存储器发起多次读取。读取的数据在被返回给请求者之前被乘以XOR'd。在PCI-X请求者的情况下，这是分裂完成。
