3.7.2 Topology and IP addressing 3.7.3 General preferences Planning for host attachments iSCSI qualified name See 3.5, “Planning IP connectivity” on page 51 for examples of topology and addressing  schemes that can be used for iSCSI connectivity.  If you plan to use node’s 1 Gbps Ethernet ports for iSCSI host attachment, dedicate Ethernet  port one for the SAN Volume Controller management and port two for iSCSI use. This way,  port two can be connected to a separate network segment or virtual local area network  (VLAN) dedicated to iSCSI traffic. Note:  Ethernet link aggregation (port trunking) or  channel bonding  for the SAN Volume  Controller nodes’ Ethernet ports is not supported for the 1 Gbps ports. This section covers general preferences related to iSCSI. An iSCSI client, which is known as an iSCSI  initiator ,  sends SCSI commands over an IP  network to an iSCSI target. A single iSCSI initiator or iSCSI target is called an  iSCSI node .  You can use the following types of iSCSI initiators in host systems: Make sure that iSCSI initiators, targets, or both that you plan to use are supported. Use the  following sites for reference: A SAN Volume Controller cluster can provide up to eight iSCSI targets, one per node. Each  SAN Volume Controller node has its own IQN, which, by default, is in the following form:  iqn.1986-03.com.ibm:2145.< clustername >.< nodename > An alias string can also be associated with an iSCSI node. The alias enables an organization  to associate a string with the iSCSI name. However, the alias string is not a substitute for the  iSCSI name. Important:  The cluster name and node name form part of the IQN. Changing any of them  might require reconfiguration of all iSCSI nodes that communicate with the SAN Volume  Controller. 70  Implementing the IBM System Storage SAN Volume Controller with IBM Spectrum Virtualize V8.2.1 http://www.ibm.com/support/docview.wss?uid=ssg1S1003658 https://www.ibm.com/support/knowledgecenter/STPVGU https://www.ibm.com/systems/support/storage/ssic/interoperability.wss GLYPH<SM590000> Software initiator: Available for most operating systems (OS), including AIX, Linux, and  Windows.
