Abstract
A primary data storage system is linked to a geographically remote secondary data storage system for automatically maintaining a remote copy of the data in the primary storage. The primary data storage system has a primary cache memory, and the secondary data storage system has a secondary cache memory. The primary data storage system controller has a first remote link adapter coupled between the primary cache memory and the communications link for transferring the data to the communications link. The secondary data storage system controller has a second remote link adapter coupled between the communications link and the secondary cache memory for transferring the data from the communications link to the secondary cache memory. In this fashion, the first remote link adapter and the second remote link adapter automatically transfer the data to the secondary cache memory for writing of the data into the secondary data storage.
