ABSTRACT:
A method to copy information to two data storage devices. The method provides a first data storage device and a second data storage device, where the first data storage device is capable of communicating with the second data storage device. The method provides first information and a write command to the first data storage device at a first time. The method determines if the write command comprises a synchronous copy attribute. If the write command comprises a synchronous copy attribute, then the method synchronously provides the first information to the second data storage device. Alternatively, if the write command does not comprise a synchronous copy attribute, then the method provides the first information to the second data storage device at a second time, where that second time is later than the first time.
