So with the setup that you are trying to do all will work but you will need to get the correct HBA for the MD3420 as you will need a 12gb SAS card & not a 6gb SAS card. Here is a link to the support matrix for the MD3420 & if you look on page 21 it list out the support SAS HBA’s & has there pert# as well so you can get the correct one for your server. ftp://ftp.dell.com/Manuals/Common/powervault-md3400_concept%20guide_en-us.pdf
Also what you will need to is to make sure that when you go to deploy this setup that you have 2 connections from each server to the MD3420 just so that your failover for shared storage will work correctly. Here is a link to the Deployment Guide as well and if you look on page 14 it shows you how to cable the system using 4 connections to each controller. You will only need to use minimum of 2 connections to each controller on your MD3420. http://topics-cdn.dell.com/pdf/powervault-md3400_Deployment%20Guide2_en-us.pdf
Please let us know if you have any other questions.
What is still unclear to me is what MPIO driver should I use in this case. As far as I understand, I will have several (2 for each host) alternative SAS paths so I will need to use some MPIO mechanism to correctly handle path selection. Am I correct? If yes please point me (if possible) to correct guide with the description of this moment.
Also, I reviewed all the available pdfs for MD3420 from the ftp link you provided and I was unable to find file with the description of correct Hyper-V CSV cluster configuration with MD3420 array connected via SAS. I understand that this process will not really differ from the Hyper-V cluster configuration with any other storage array but just to make sure: do you have such guide? I found the following blog post describing Hyper-V shared storage cluster configuration for MD3220i array using iSCSI: faultbucket.ca/.../hyper-v-failover-cluster-setup and I think this post pretty much the same for SAS case with several distinctions...

Hi Sam!
