Document Type and Number:
WIPO Patent Application WO/2017/113351
Kind Code:
A1
Abstract:
An active-active system. A method comprises: if a write lock privilege is possessed by a second storage array, a first storage array sends data to be written together with a lock recall request to a lock server; the lock server sends the lock recall request carrying the data to be written to a second lock server; the second lock server sends a lock recall success message to the lock server after storing the data to be written; the lock server gives the write lock privilege to the first storage array; the first storage array obtains the write lock privilege to store the data to be written. By means of the method, data to be written is stored in two storage arrays in a relatively short process.
