[gpfsug-discuss] Asymetric SAN with GPFS

is there any settings for GPFS 5.x so that you could mitigate slow down of
asymmetric SAN? 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?
