Both the configurations are valid. check this doc. [URL] (Pg no 16)  EMC recommends Round Robin, the built in PSP's should work just fine but if you wish you can also use PowerPath for centralized management etc.  Hope this helps!
Hello everyone,  the VNXe 3200 is my first EMC storage and I have a few questions about direct attached ESXi hosts over iSCSI.  I want to attach two ESXi 5.5 hosts directly over 10Gb Ethernet to the storage.  Let me tell you how I understand the procedure so far:  The manual says that every iSCSI target must have two IP addresses for HA. In Unisphere I can set two IP addresses for every 10Gb Ethernet port because the system sees the eight ports combined as for ports (4 on controller A, 4 on controller B), right? So the first address is for expample for Port 1 on controller A and the second address is for Port 1 on controller B.  If I had one or two 10Gb Switches then iSCSI would go over them. And the second address for port 1 on controller B would be passive as long as controller A is running.  But I want to attach the ESXi hosts directly to the storage, so Port 1 of the ESXi host wouldn´t be able to see Port 1 on controller B because its connected directly to Port 1 on controller A. Every host has two 10Gb Ethernet ports. So I just have to connect Port 1 on Controller A with Port 1 of an ESXi host. I cannot use Port 1 on controller B for Port 2 on the ESXi host, right? I have to connect it Port 2 of the ESXi host to Port 2 of controller B so the host sees both controllers.  And that leads to the next question: Do I need the PowerPath software on the ESXi hosts when they are NOT connected to the storage over switches? As far as I understand the PowerPath software is for scenarios where one ESXi Port can see at least two storage ports. For example ESXi Port 1 sees Storage Ports 1 on controller A and controller B and only switches from A to B, when A fails.  I´m sorry if I explained myself unclear. If you need additional information, please let me know.  Any help would be highly appreciated. So thanks in advance [IMAGE].
