That subnet layout is very wrong. You'll want to use 4 subnets (like the factory default settings). When changing from the factory defaults, do something like this: Controller 0 Port 0: 192.168.130.101 -> 10.10.1.101 Controller 0 Port 1: 192.168.131.101 -> 10.10.2.101 Controller 0 Port 2: 192.168.132.101 -> 10.10.3.101 Controller 0 Port 3: 192.168.133.101 -> 10.10.4.101 Controller 1 Port 0: 192.168.130.102 -> 10.10.1.101 Controller 1 Port 1: 192.168.131.102 -> 10.10.2.101 Controller 1 Port 2: 192.168.132.102 -> 10.10.3.101 Controller 1 Port 3: 192.168.133.102 -> 10.10.4.101 In other words; "Ports 0" on 1 subnet, "Ports 1" on a second subnet, "Ports 2" on a third subnet and "Ports 3" on a fourth subnet. As you can only use 2 ports on each blade for iSCSI in your setup (due to the dual lan ports on the motherboard), you have some blades use 10.10.1 + 10.10.2 and other blades use 10.10.3 + 10.10.4. This lets each blade use 2 ports per controller, which matches the number of NIC ports used for iSCSI on that blade. I usually 'stagger' the ports between the fabrics (0 to A1, 1 to A2, 2 to A1 and 3 to A2).
Dear all, I am requiring information on the configuration of iSCSI. I'm supervising a IT solutions company who are installing a M1000e with 6 x M670 blade servers and a MD3200i SAN. They are wanting to do the following configuration: MD3200i controller 0 port 0: 10.10.1.101 controller 0 port 1: 10.10.1.102 controller 0 port 2: 10.10.2.101 controller 0 port 3: 10.10.2.102 controller 1 port 0: 10.10.1.103 controller 1 port 1: 10.10.1.104 controller 1 port 2: 10.10.2.103 controller 1 port 3: 10.10.2.104 All subnet masks 255.255.255.0 The 10.10.1.X network would then connect to a Powerconnect M6348 in slot A1 and the 10.10.2.X network connects to Powerconnect M6348 in slot A2.  The A slots will only be used for iSCSI They also have M6348 in slot B1 and B2, which will be used for  LAN connectivity and Management LAN. Slot A1 and A2 can only use half of the port on the M6348 as they have only 2 LOM. I think that the company should use slots B1 and B2 for the iSCSI. Can you please give technical suggestions on what would be better, the above configuration using Slots A1 and A2 or  Dell's default configuration of 4 different subnets and the use of slots B1 and B2 Thanks
