Need Help in DR Site Design

Latest reply: Mar 1, 2016 13:44:53 1911 2 0 0 0

Dear Fellows,

We are making a Disaster Recovery site of our Primary Site (Data Center). I have questions that I am confused in:

1) Network Design
      We have many servers that must be connected to core. What is the best model to design a scalable data center.
  a) The traditional 3 layered Model (Access/Distribution/Core Layer).
  b) The Top of the Rack Design Model. (1 TOR switch per rack and all the TORs are connected to Core)

2) What will be the IP Address Schema in DR-Site. Should it be same or different ? Currently, we are using private address schema (192.168.x.x/16) in our whole data center. This question is very important because of the Database replication that would be done from exisiting data center to DR-Site.

3) How should Existing Data Center be connected to DR-Site for database replication.
  1) Dark Fiber Direct Link. (It may not be possible)
  2) Connectivity through MPLS cloud.

I will be grateful if you could also share any helpful document/link regarding DR-Site data center.

I highly appreciate your time and help. Thanks.
