Somewhere on video.google.com is a Google I/O talk explaining the hell that is active/active redundancy and how hard it is to achieve at layers 4-7. I don't argue that it's the proper method for Layer 3 though. -brandon On Wed, Oct 28, 2009 at 12:38 PM, Roland Dobbins <rdobbins@arbor.net> wrote:

I'm wondering what are the growing trends in connecting Data Centers for
redundancy in DR/COOP environments.
'DR' is an obsolete 40-year-old mainframe concept; it never works, as funding/testing/scaling of the 'backup' systems is never adequate and/or allowed.
Layer-2 between sites is evil, as well.
