hv some questions..

what are scenarios one would use 2D+2P & 3D+1P, 4D+4P, 7D+1P, 14D+2P & why ?

whts the prefered emulation, Open V with specific fixed sizes (20 G for example) & later combine the LDEVs in LUSEs ? or LDEVs with the exact sizes required by the customer or any other variations like 2 LUNs for each VG & use striping or at least alternate paths?
