How are you proposing to replicate the data between the sites? You mention no IP connection, so were you planning some other form of data shipping?
I would suggest it would be a very high risk strategy to try this. Stretched cluster or ASYNC-DR are more appropriate for this type of DR solution.

Let me explain: Context: - site A simple three node cluster configured (AIX nodes). two failure groups. two filesystems. No quota, no ILM. - Site B the same cluster config as in site A configured (AIX nodes) same hdisk device names used as in site A for each and every NSDs - NO TCPIP connection between those two sites. Same ip addresses available locally on each one. and same non-scale based filesystems. Same scale version installed. (esentially site B is a copy from site A). My question is, can I replicate the spectrum scale disks from site A to site B storage to another (HP 3PAR) and maintain consistency between scale sites? can this be considered a valid DR configuration? People here don't want a stretch cluster (without any apparent reason, which talks very bad about them). Thanks. _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
