As long as you are using a licensed installation of Powerpath for multipathing, then yes you will see peformance benefits from having multiple ports per SP masked to the host. For the majority of hosts I don't see a benefit of masking more than one SPA and SPB port per fabric (which results in two ports per SP) as the limitation is usualy in the host logical drive queue not the fabric or front end ports. But for high i/o hosts it doesn't cost you anything to zone in more ports and monitor the performance. Play around with it and see what helps.
Hello,  I was wondering if this was a normal best practice these days.   I have been looking at a customers configuration and noticed in "connectivity status" that all the hosts were not zoned to all of the storage proccessors FE ports.  For example, we have a CX4-240 in the standard config.  So i would think that i should see (4) initiator records under each host (SPA 2-3 & SPB 2-3) but i only see one port (2) from each SP.   My past experience has that each host gets zoned to all SP ports unless you have a port used for SanCopy or Mirrorview.  They are not anywhere close to the initiator limit for the array.  This config was done in the past by someone that is not there anymore and before i recommend that we add zones for all the other ports, it is a good idea.  I would think that having all the ports zoned would help with load balancing.  THe enviroment is a mix of W2003 and vSphere.  Any advice would be great.  THanks
Is not having all SP ports zoned normal on CX4?
