That applies only to Windows and Linux hosts that connect. Not to VMware (ESX/ESXi) hosts. I highly recommend to review www.delltechcenter.com/.../VMware+ESX+4.0+and+PowerVault+MD3000i to get an idea how to set up an ESXi system to properly use an MD3-series array. The MD3220i has 4 iSCSI ports per controller, so if you want to use all 4, you will need 4 subnets and 4 NICs (for iSCSI), instead of the 2 that that link shows for the MD3000i (predecessor to the MD32xxi).
Hi, We bought a MD3220i to use as shared storage for our vmware datacentre. I'm a little bit confused by the documentation.. it states that  it needs Host software installed on each host that will connect to the MD3220i and the the software contrains:  the necessary storage agent and multipath driver. And that all host servers that connect to the storage array need it. Presumably this also includes the ESXi hosts??  If so - how do i install that on the ESXi hosts? ADvice would be appreciated, S.
