DR site

Unanswered Question
Apr 10th, 2007


I have a primary datacenter and am planning to have another datacenter which would be the DR Site. What Cisco products should be used for having a DR Site and how can I implement it.

Best Regards,


I have this problem too.

GSS is just one part of the overall end-to-end solution. Howerver there are many other pieces to the puzzle. Here a just a few:

-SAN Replication

(powered by a storage vendor solution like EMC RecoverPoint or HP Continuous Access ... either one enabled by a Cisco MDS SAN fabric)

-Load Balancers

(provides a level of abstraction & virtualization of the application IP address and the server IP address -- thus making failing over an application to another site much easier ... ACE - CSM - CSS)

-Server Virtualization

(VMWare or VFrame - provides a level of abstraction and virtualization of the applicaion and OS from the physical server hardware -- thus making failing a server transparent to the application)

-Optical -- DWDM and CWDM

(often the best choice for a separate back-end datacenter-to-datacenter connection -- powered by a darkfiber service provider such as Above NET and Cisco ONS)


(to provide site selection based on health as assesed by your Load Balancers)

** See attached diagram I have developed showing the end-to-end multi-datacenter solution **

I use this diagram when I have discussions with Cisco customers like yourself about how to implement multiple datacenters with the latest technology Cisco has to offer.

Hope this helps. Please give this post a quick rating ;)

Hello Brad ,

I am planning for Disaster Recovery site and Data Center Site. Your networking drawing is really helpful to design the DR site and DC site implementing.

I am planning for VFrame with VMWare ESX servers with VMotion and VDI too.

Could you please send me the Visio file, so i can customize it and share with the Netpro group too for discussions and clearing some doubts. Here is my address [email protected]
