i would not bother with 2nd method unless you really need 4 active paths for performance (not likely your backend push that fast anyway) , VMAX is active/active so you can write to any port on VMAX.
Hi All,     I have to implement SANCOPY data migration between Clariion and VMAX and obviously it is going to be an incremental push. I have few questions before I proceed,  1. ZONING:  Planned to use 4 front end ports from Clariion and VMAX.For example SPA0 & SPB2 (fabric A) and SPB1 & SPA3 (fabric B) VMAX - 8H0 & 10H0 (fabric A)  and 7H0 & 9H0 (fabric B)  what is the best practice for zoning pertaining to SANCOPY 1st method  SPA0 to 8H0 SPB2 to 10H0 SPB1 to 7H0 SPA3 to 9H0  or  2nd method  Do we really need SP redundancy at Clariion end? Please explain.  SPA0 to 8H0   & SPB2 to 8H0 SPA0 to 10H0 & SPB2 to 10H0 SPB1 to 7H0   & SPA3  to 7H0 SPB1 to 9H0   & SPA3 to 9H0  Thanks Dino
