Many ? IMHO it is not that much. I do not like to have one server doing more than one task. Thus a NSD Server does only serves GPFS. A Protocol server serves either NFS or SMB but not both except IBM says it would be better to run NFS/SMB on the same node. A backup server runs also on its "own" hardware. So i would need at least 4 NSD Server since if 1 fails i am losing only 25% of my "performance" and still having a 4/5 quorum. Nice in case an Update of a NSD failed. Each protocol service requires at least 2 nodes and the backup service as well. I can only say that with that approach i never had problems. I have be running into problems each time i did not followed that apporach. But of course YMMV But keep in mind that each service might requires different GPFS configuration or even slightly different hardware. Saying so i am a fan of having many GPFS Server ( NSD, Protocol , Backup a.s.o ) and i do not understand why not to use many nodes ^_^ Cheers Hajo _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
