Simultaneous concurrent and cascaded triangular asynchronous replication

A method of providing storage configurations for a data center, comprising:

• providing synchronous data transfer from the data center to a local destination;
• establishing a first connection between the data center and a remote destination to provide chunks of data from the data center to a remote destination, wherein each chunk of data represents data written after a first time and before a second time and wherein the second time for one of the particular chunks corresponds to a first time for a subsequent one of the particular chunks;
• establishing a second connection between the local destination and the remote destination to provide chunks of data from the local destination to the remote destination, wherein each chunk of data represents data written after a first time and before a second time and wherein the second time for one of the particular chunks corresponds to a first time for a subsequent one of the particular chunks;
• and
• enabling at least one of the first and second connections to transfer chunks of data to the remote destination.

Computer software, provided in a computer readable storage medium, that provides storage configurations for a data center, the computer software comprising:

• executable code, executed by a processor, that provides synchronous data transfer from the data center to a local destination;
• executable code, executed by a processor, that establishes a first connection between the data center and a remote destination to provide chunks of data from the data center to a remote destination, wherein each chunk of data represents data written after a first time and before a second time and wherein the second time for one of the particular chunks corresponds to a first time for a subsequent one of the particular chunks;
• executable code, executed by a processor, that establishes a second connection between the local destination and the remote destination to provide chunks of data from the local destination to the remote destination, wherein each chunk of data represents data written after a first time and before a second time and wherein the second time for one of the particular chunks corresponds to a first time for a subsequent one of the particular chunks;
• and
• executable code, executed by a processor, that enables at least one of the first and second connections to transfer chunks of data to the remote destination.
