Title:
SYSTEM AND METHOD FOR EASILY SHARING RESOURCE SUCH AS STORAGE SUB-SYSTEM BETWEEN PLURAL HOST COMPUTERS IN DIGITAL DATA PROCESSING SYSTEM
Document Type and Number:
Japanese Patent JP2000099448
Kind Code:
A
Abstract:
To make it possible to share one or plural resources such as disk storage devices between plural host computers by constituting a host processor so as to selectively adjust at least one constitutional switch to a pass through mode or a by-pass mode.
The system includes two data storage processors(DSPs) 101, 102 connected to two disk storage arrays '6-pack' 200 as host computers. These DSPs 101, 102 are general computer systems having software modules and hardware modules for storing and processing data and connection to FC loops 160, 170 and a bus 150. The host processor can connect many or less drive modules through the loops by selectively adjusting the constitutional switch to the pass through mode or the by-pass mode.
