Abstract
A system for busing data in a DASD controller is described. The system includes adapters serving computer elements such as processors and disk arrays. Cache memory in the controller is divided amongst memory cards. At least one switch is connected to each memory card. Bidirectional multichannel serial links connect each adapter with a switch. Each switch can establish at least one path between each adapter connected to the switch and each memory card.
Claims14
A system for busing data in a direct access storage device (DASD) controller, the DASD controller serving a plurality of computer elements, the system comprising:
- a plurality of adapters, each adapter in communication with one of the computer elements;
- a plurality of memory cards;
- at least one switch, each switch in communication with each memory card;
- and
- a plurality of bidirectional multichannel serial links, each link connecting one adapter to one switch;
- wherein each switch is operable to establish at least one path between each adapter connected to the switch and each memory card.
