I know Powerpath gives us the ability to load balance between 2 HBA cards. But, can we do the same thing with 4 cards? How about 8? Is there a limit on powerpath and load balancing between HBA cards?
The EMC PowerPath Product Guide shows the use of 4 cards and I have used 8 cards before (as long as they are all the same cards) I am not sure what the upward limit is but I have heard of people using 32 cards before on very large systems. How many did you want to use?
PowerPath's limit is 32 PATHS, this could be achieved with as few as two HBA's depending on how many different FA ports you wish to map the devices though.
I believe that this is a limit to the number of paths to a single device. Powerpath can manage in the thousands of total paths to seperate devices, I believe 4096 is the total path limit.
