Abstract:
A data storage system wherein a host computer section having host computer processors for processing data is coupled to a bank of disk drives through an interface, such interface comprising:(A) a plurality of addressable memories coupled to a bus;(B) a plurality of controllers coupled to the bus, each one thereof being adapted to request a data transfer between the bus and an addressed one of the addressable memories, each such request being transmitted to the addressed one of the memories in a series of bursts, each one of the bursts in a request having a tag unique to such request;wherein each one of the addressable memories has:(i) an error detector for detecting an error in the addressable memory transferring data between the bus and the addressable memory; and(ii) a control logic section for storing a cumulative error message produced in response to the error detector processing each one of the bursts of requests and for reporting the cumulative error to the one of the controllers making such request at the end of the series of bursts.
