  • Page 23: Setting The Mtu

    Setting the MTU Enabling larger frames on a jumbo frame-capable network can improve your network throughput. Jumbo frames are Ethernet frames that contain more than 1500 bytes of payload (MTU). Before enabling jumbo frames, ensure that all the devices/hosts located on the network support the jumbo frame size that you intend to use to communicate with the Gateway.

  • Page 24: Setting The Ip Address

    Important: Some networking switches require you to specify the size of the jumbo frame (MTU) when enabling, as opposed to a simple enable command. On these switches it might be required to add the necessary bytes needed for the frame header to the MTU size you specify in the Gateway’s port configuration.

  • Page 61: Appendix B Connecting To An Iscsi Device Using The Microsoft Iscsi Initiator

    Connecting to an iSCSI Device using the Microsoft iSCSI Initiator There are many iSCSI Initiators available. However, for the purpose of this user guide we shall concentrate only on the Microsoft iSCSI Initiator. In this example we have used the Microsoft iSCSI Initiator that is available with Microsoft Vista.

  • Page 62: Discovery Of Devices

    Enter in the CHAP (Initiator) Secret and click OK. The secret should be between 12 and 16 characters. Make a note of this secret as you will need to enter this as part of configuring CHAP on the iSCSI Gateway. Discovery of Devices Before you can connect to an iSCSI Target, the iSCSI targets must be discovered.

  • Page 63: Adding An Iscsi Target Portal

    • Adding an iSCSI target portal and directly performing a discovery; • Adding an iSNS server to which the target portal is registered. Adding an iSCSI Target Portal To add an iSCSI Target portal, click on Add Portal. You should now be presented with the following window: Enter the IP address for the iSCSI Target.
  • Page 64 The Connect by using section allows you to specify which iSCSI adapter to use and the Source IP. The Local adapter should only differ from Microsoft iSCSI Initiator if an iSCSI offload card has been installed. For the purpose of this guide, we shall only use the Microsoft iSCSI Initiator. Leaving this setting as Default will also use the Microsoft iSCSI Initiator.

  • Page 65: Adding An Isns Server

    Note: For mutual CHAP to be performed, the Initiator Secret must be set on the general tab, and be the same as the one configured on the iSCSI Gateway. Note: The use of RADIUS is beyond the scope of this guide. Once you are satisfied that all advanced options are correct, click OK.

  • Page 66: Connecting To A Target

    Enter the address of the iSNS server with which your iSCSI Gateway is registered, then click OK. The Microsoft iSCSI Initiator will now query the iSNS server and perform discoveries on registered target portals. Click on the Targets tab. The discovered devices should now be listed. In this example two iSCSI targets have been discovered.
  • Page 67 If you wish to reconnect to the target automatically when this Windows server reboots, select the Automatically restore this connection when the computer starts checkbox. Click on the Advanced button to see the advanced settings. The following window should appear: The Advanced Settings page is the same as that of the discovery except for one addition.
  • Page 68 Interfaces subsection, on the iSCSI Target page of the iSCSI Gateway’s web interface: See Chapter 5: iSCSI Target Configuration for more information. Important: If you wish to connect to a target over multiple network interfaces, see Appendix B.5: Creating Multiple Connections (Optional).

  • Page 69: Viewing Iscsi Session Details

    Viewing iSCSI Session Details When you have connected to an iSCSI Target, you can check that the device is connected by clicking on the Details button. The following window will appear:...

  • Page 70: Creating Multiple Connections (Optional)

    In this window you can view the iSCSI Sessions associated to the iSCSI Target, how many connections are attached to each iSCSI Session, and the Target Portal Group. If you click on the Device tab, details of the target device will be displayed. Here for example, we can see that the device is an IBM LTO Tape drive.
  • Page 71 Click on the Connections button to open the Session Connections window: This shows how many iSCSI Connections are active and the type of load balance used. For all iSCSI Sessions, there will be at least one leading connection. iSCSI connections can be added and removed at any time, all apart from the leading connection, which can only be removed when the iSCSI Session is logged off.
  • Page 72 Note: The Load balance policy specifies how the data is distributed over multiple connections. The main policies that should be used are Round Robin and Fail Over Only: Round Robin will utilize all connections for data and evenly distribute the data.
  • Page 73 In the Connect by using section, select the Source IP address and the Target portal address for the new connection. In most instances these should be different from the source and target addresses of the original connection. In this example we have connected to 10.10.10.50 / 3260 as the leading connection, and the second connection will be 10.10.11.50 / 3260.
  • Page 74 Note: Up to 8 connections can be added to one session. Once you have completed setting up the connections, click OK to return to the Target Properties page. Under Session Properties, you will see that the Connection count field value has increased:...
