I have seen some Storage High-End disk subsystems supporting over 60 thousands LUNs and there are some others companies offering a high-end product varying the maximum number of LUN between 2048 and 4096.
Can we assume how high is the number of LUN it is better the High-End Storage product?
In terms of capacity & performance analysis: Is there any math to find out the best relation between the number of LUN (capacity) and the maximum data transfer (performance)?
OBS: I know we have some capacity/performance constraints at the File Systems, HBA driver/firmware, switches and storage controller while the number of LUNs is increased.
