SFCFS HA data synchronization across multi data center

Hello,l

You can implement VVR which is an extention of VxVM (license required).

VVR can replicate data from one primary to one or many secondaries.  Some of the the volumes on one site cam be primary and some voluemso the same site can be seconday of other site as well per your need.  Please consult with VVR admin guide on http://sort.verityas.com/documents.

To replicate large amount of data, a decent network is a must.

Cheers,

Frank
