load balancing iSCSi

[hurdle]

I noticed in one of the guides they reocmmend that you use two different vmkernal ports with two different subnets to load balance an acitve/active storage aray.   Is the two different subnets a requirement.  If so, why?  Our entire storage solution is currently one on subnet  and doing some modifications to it is not an option at this time.

Have a read through this blog post article is it would answer your question: http://paulgrevink.wordpress.com/2011/07/26/configure-vmware-esxi-4-1-networking/

Best wishes and hope this helps.

For many vendors, it's a SAN vendor recommendation.

Follow your vendor's recommendations, if they recommend using a single subnet then you should be fine.
