Surely you would need to use different data pools for this. Given in a single pool data will be distributed over all available nsd devices in that pool, you are highly likely to only ever go as fast as the slowest LUN.

The asymmetric SAN means, that not every LUN has the same speed, or not every disk array has the same number of LUNs. It seems that overal speed is degraded to the slowest LUN. Is there any workaround for this except avoiding that LUN at all? -- Lukáš Hejtmánek Linux Administrator only because Full Time Multitasking Ninja is not an official job title _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
