[c-nsp] Solution for 'DR' Site

[Sanjeev Maniks]

Dear Andrew,

Thanks for your comment.   At the moment the bank is already mirroring the data between the primary and DR sites and have now requested that we not provide any communication channel through our network for this purpose.  So we will in effect be providing the channel for their external clients to access their Internet Banking Platform either from the Primary or DR site should the former go offline.  The only other service that requires external access will be SMTP/POP3.

Please let me know if you require any further information.

Thanks,

Sanjeev

If it meets their needs, the simplest way would probably be to use separate

IP space at each site, with DNS based load balancing to fail their

applications over to the DR site.


DNS has nothing to do with load balancing.
The original poster mentioned that he was looking for a DR solution for a bank, but unfortunately did not include any real requirements.

These requirements would need to be done on a per application basis and could include everything from SAN mirroring to complete backup trading rooms.
Collecting the requirements themselves would already be a large project....
