Abstract:
A method for accessing mirrored shared logical memory modules for a read comprising:sending a memory request for a read to an interface from a requester and then to said shared logical memory modules;formulating a reply at each shared logical memory module indicating a size of a mirror set, where said mirror set comprises said shared logic memory modules;formulating said reply at said each shared logical memory module so as also to indicate whether said each shared logical memory module is in a transitional state;formulating said reply at said each shared logical memory module so as to combine indications of said size of said mirror set and indications whether said each shared logical memory module is in a transitional state into a set-mode indicator;sending each said reply to said interface;deriving at said interface, from one or more replies, a second message; and,forwarding said second message to said requester from said interface.
