Q.)  Would like to get some feedback on our D2D LBR – how resilence is it when replicating over VSAT ultra-low bandwidth (32kb-64kb) where packets are liable to drop. Would our D2D LBR solution be able to stop/start/resume replication depending on the condition of the link as required?

 

A.) To answer your original question, the D2D devices allow you to ?throttle-down? the amount of network bandwidth they use for the replication, but the minimum setting they offer is 512 Kb/sec.  Dropped packets would be handled by the network protocol, not the D2D, but a dropped link can be handled by the D2D (it would restart the replication from a previously ?known good? point and continue on).  There?s a great white paper on this topic available at http://h20195.www2.hp.com/V2/GetPDF.aspx/4AA2-4142ENW.pdf if you want to understand this further.  Using the D2D replication across an ultra-low bandwidth link will not result in a good customer experience.
