Operating system for generating overlapped input-output requests to a device in a disk array storage |
摘要 |
A method for enabling a data processing system with a host running under an operating system and with a disk array storage device organized by logical devices to process panel I/O requests to a logical device from one or more host processors concurrently. The system includes a parallel access control block that identifies unit control blocks assigned to the same logical device. If an I/O request is received while a main UCB unit is busy, the main control block identifies another unit control block to enable an overlapped access to the logical device.</PTEXT>
