I'm having a problem with a MD3200i and our new T710 virtual server - it works, but performance is absolutely abysmal.  Here's the details....

Server is a T710, 4 onboard nics + a 4 port Intel Server NIC.  Its running the latest update of ESXi 4.1 - right now it has 6 hosts on it, going to be 10 total (most are lightly loaded special purpose servers). Server is connected to the SAN by 4 cables direct from the 4 port Intel Server NIC to the 4 ports on the management controller

We have 4 drives (2TB SAS) in the SAN - not my first choice - but what the customer wanted. Array is set up as a RAID-10.  We have 3 logical volumes - 2 TB, 1 TB, and 750 GB.  Each is formatted as a VMFS datastore.

I followed the instructions in the Dell whitepaper for setting up the MD3200 with ESX 4.1 and it doesn't appear we have multpathing working correctly.  The VCenter Client is only showing 6 paths usable - should be 12 total (3x volumes * 4 network cards).

I've gone through the docs a handful of times, can't find anything that strikes me as an obvious problem.  Below is the output of some of the commands in the documentation - if anything else would be helpful let me know.  I feel like i'm running in to a brick wall here, any advice would be great!

Thanks in advance....
