A disaster-tolerant data backup and remote copy system which is implemented as a controller-based replication of one or more LUNs (logical units) between two remotely separated pairs of array controllers connected by redundant links. In the situation wherein an array controller fails during an asynchronous copy operation, the partner array controller uses a ‘micro log’ stored in mirrored cache memory to recover transactions, in order, which were ‘missed’ by the backup storage array when the array controller failure occurred.

A method is provided for asynchronous notifications from a device to a host in systems without requiring hardware provision for asynchronous operations. In an embodiment of the invention, a system supports command queuing and a command is sent from a host to a device. The device receives the command and an associated tag, and accepts the command as valid. After accepting the command, the device begins monitoring for asynchronous events. If an asynchronous event is detected, the device provides notification of the event by sending a response and the associated tag to the host. In another embodiment of the invention, a method of asynchronous notification enables use of invalid tags. In a further embodiment of the invention, asynchronous notifications may be enabled by a host and operate without additional host commands.

The two clock signals H1 and H2 are of different frequencies respectively and issue from two different first (OSC1 and OSC2) operating asynchronously from one another and not adhering to the setup time of the logic circuit (10). The logic circuit is arranged to deliver at an output a signal in an intermediate state qualified as metastable between "0" and "1" and being constituted by a random number sequence.

An internal memory stores the random numbers obtained as output signals from the pseudo-random generator. The two generators run on the same second "high frequency" clock H generated by the external oscillator (7).
