14 Copyright © 2017 Dell Inc. Microsoft Internet iSCSI Initiator enables you to connect a host computer that is running Windows Server 2008, Windows Server 2008 R2 Windows Server 2012 and Windows Server 2012 R2 to an external iSCSI-based storage array through an Ethernet network adapter. You can use Microsoft iSCSI Initiator in your existing network infrastructure to enable block-based storage area networks (SANs). SANs provide iSCSI target functionality without investing in additional hardware. The Microsoft iSCSI initiator does not support booting the iSCSI host from iSCSI storage. Refer to the Dell EMC Support Matrix for the latest information about boot device support. All iSCSI nodes are identified by an iSCSI name. An iSCSI name is neither the IP address nor the DNS name of an IP host. Names enable iSCSI storage resources to be managed regardless of address. An iSCSI node name is also the SCSI device name, which is the principal object used in authentication of targets to initiators and initiators to targets. iSCSI addresses can be one of two types: iSCSI Qualified Name (iQN) or IEEE naming convention, Extended Unique Identifier (EUI). Within iSCSI, a node is defined as a single initiator or target. These definitions map to the traditional SCSI target/initiator model. iSCSI names are assigned to all nodes and are independent of the associated address. Unity Learning Center

15 Copyright © 2017 Dell Inc. The Linux operating system includes the iSCSI initiator software . The iSCSI driver open-iscsi comes with the Linux kernel. You must configure this open-iscsi driver with the network parameters for each initiator that will connect to your iSCSI storage system. Dell EMC recommends changing some driver parameters, refer to the Unity Family for Configuring Hosts to Access Fibre Channel (FC) or iSCSI Storage Guide for the driver parameters. Note: The Linux iSCSI driver gives the same name to all network interface cards (NICs) in a host. This name identifies the host, not the individual NICs. This means that if multiple NICs from the same host are connected to an iSCSI interface on the same subnet, then only one NIC is actually used. The other NICs are in standby mode. The host uses one of the other NICs only if the first NIC fails. Each host connected to an iSCSI storage system must have a unique iSCSI initiator name for its initiators (NICs). If multiple hosts connected to the iSCSI interface have the same iSCSI initiator name, the administrator must contact the Linux provider for help with making the names unique. Unity Learning Center

16 Copyright © 2017 Dell Inc. Host configurations are logical connections through which hosts or applications can access storage resources. They provide storage systems with network profiles of the hosts that use storage resources, based on the protocol used: FC or iSCSI (block), or SMB or NFS (file). Before a network host can access storage, you must define a configuration for it and associate it with a storage resource. The example shows a host configuration created in Unisphere for a Windows host with a registered iSCSI initiator.
