DIRECT BULK DATA TRANSFERS |
摘要 |
A data processing system for transferring data is provided. This system includes central processing units (CPUs 20, 22, 24 and 26) and storage units (30 and 32 with 100-105 and 110-115) which are interconnected by a network (10). The CPUs (20, 22, 24 and 26) include a request process (133) and a storage process (130). The storage process (130) controls access to the storage unit (30 with 100-105 and 110-115). Software routines (220) are used to provide direct access to the storage unit (30 with 100-105 and 110-115) by the request CPU (22). The request CPU (20) is the CPU containing the request process (133). A virtual memory address for a buffer (160) of the request CPU (22) is created in the request CPU (22). The virtual memory address along with a storage unit access request are sent to the CPU (20) containing the storage process (130). A work request including the virtual memory address to sent from the storage process (130) to the storage unit (30 with 100-105 and 110-115). The data is then transferred directly between the request CPU (22) and the storage unit (30 with 100-105 and 110-115). The storage unit (30 with 100-105 and 110-115) then responds to the work request.
