System and method of replicating virtual machines for live migration between data centers

摘要

A method of replicating tiered data includes copying a volume from a first tiered storage array of a primary processing site to a second tiered storage array of a failover processing site, wherein the volume is tiered with a first tiered organization in both the first and second tiered storage arrays, directing from a first storage controller of the primary processing site that a second storage controller of the failover processing site stop tiering the volume on the second tiered storage array, changing the first tiered organization of the volume in the first tiered storage array to a second tiered organization, and changing the first tiered organization of the volume in the second tiered storage array to the second tiered organization.

1. A method of replicating tiered data, the method comprising:
copying a volume from a first tiered storage array of a primary processing site to a second tiered storage array of a failover processing site, wherein the volume is tiered with a first tiered organization in both the first and second tiered storage arrays; directing from a first storage controller of the primary processing site that a second storage controller of the failover processing site stop tiering the volume on the second tiered storage array; changing the first tiered organization of the volume in the first tiered storage array to a second tiered organization; changing the first tiered organization of the volume in the second tiered storage array to the second tiered organization; detecting an event at the primary processing site; initiating tiering of the volume by the second storage controller in response to the event; changing the second tiered organization of the volume in the second tiered storage array to a third tiered organization; detecting an end to the event at the primary processing site; and changing the second tiered organization of the volume in the first tiered storage array to the third tiered organization in response to detecting the end of the event.
