Hi, what is better to have - more LUNs or more Storages. Actually i have 1 storage ESXi per 1 LUN so there are about 15 LUNs and 15 storages. Now there is a kind of problem because the LUNs have different space allocated so if i remove 2 LUNs f.e. 1 2 3 4 [x] 6 [x] 8 9 (like that) i can't make 1 LUN from 5 and 7 pieces of free diskspace on IBM storage array. It's a first argument to not have a lot of LUNs. If i had to make only a few LUNs (about 3) and inside some Storage from ESXi would it be a better idea? For example for expanding storage capacity? i look for good solutions.

Thanks in advance.
