    Abstract: A digital data storage system having a switching arrangement permitting storage devices to be shared by two separate controllers, each of which in turn receives commands and transfers the stored data to a different data processing system. The arrangement involves a plurality of subchannels (01, 1, 2, 3) each of which comprises at least one addressable storage device (0;....N) and two addressable interlocked port switches (0, 0 min ) each of which functions to connect one side of the subchannel and the device to one of the controllers (10, 10 min ). The subchannel switching arrangement is characterised by each switch being addressable as if it were another device, which permits the port switches to be implemented with minimal changes to either the controller or the device.

    Abstract: Se suministran un aparato, sistema y metodo para facilitar el manejo de almacenamiento, a traves de la organizacion de los recursos de almacenamiento. El aparato incluye un modulo de configuracion, que configura una primera entidad logica y una segunda entidad logica, para interactuar entre si en un dominio de igual a igual, de manera que cada entidad logica sea una imagen en espejo de las operaciones de, y este en comunicacion directa con, la otra entidad logica. Un modulo de informacion expone los recursos locales de la primera entidad logica y los recursos locales de la segunda entidad logica, a un nodo de manejo, de manera que estos recursos locales estan disponibles como recursos objetivo de un comando de manejo desde el nodo de manejo. Un modulo de direccion dirige selectivamente un comando de manejo desde el nodo de manejo hacia un recurso local de la primera entidad logica y/o un recurso local de la segunda entidad logica, segun se determina por el tipo de comando de manejo.
