EqualLogic iSCSI SAN -- really needed ?

Would just adding a DAS when needed be OK since
I only have two PHYSICAL servers and don't want
to pay lots for an EqualLogic iSCSI SAN setup ?
  ** two big PHYSICAL servers, each running
     four production Windows Server 2012 VMs
       ** VM #1 = production file,
                  DHCP, print, etc server
       ** VM #2 = production Database server
       ** VM #3 = production Application server
       ** VM #4 = production Exchange server
       ** VM #5 = production SharePoint server
       ** VM #6 = etc
       ** VM #7 = etc
       ** VM #8 = test server

  ** BACKUP --> between both PHYSICAL servers
       ** Every 5 Minutes = Microsoft SQL logs
       ** Every Hour = documents and everything else

  ** RECOVERY --> between both PHYSICAL servers
       ** If VM in one server goes down for 5+
          minutes I just bring the other
          server's VM backup online

    A SAN is required if you want to implement a failover cluster. Otherwise, no, it is not required. However, in case where one of your server is down, you won’t be able to move the virtual machines to the other one.

    You only require a SAN, shared storage if you want to do Live Migration, Cluster and HA, but there is no reason why you cannot take your project forward as described and save money.

    Extra Availability and Redundancy is all about how much Budget you've got.

    A DAS is fine.

    Also using Hyper-V replica you can replicate yours VMs from Host A to Host B, giving youself extra redundancy.
