iSCSI (Internet SCSI) CommandsAbout iSCSI storage systems in IP networksAn iSCSI storage system, such as the CX500i, connects directly to anIP network. Servers with either iSCSI HBAs (host bus adapters) orEthernet connections can access the iSCSI storage system through anIP network, such as a local area network (LAN).A LAN is a set of point-to-point connections between nodes, witheach node having its own unique IP address. Connections are madethrough one or more network components such as switches or hubs.Nodes are connected through a LAN by Ethernet CAT 6 (for GigabitEthernet LAN) and CAT 5 (for 10/100 LAN) copper cables. Networkswitches are not nodes.Each node in an iSCSI environment is either an initiator (server) or atarget (storage system). Figure 5 shows an initiator node and a targetnode.Server Adapter (Initiator)NodeAdapterConnectionStorage System (Target)NodeEMC1802Figure 5Nodes - initiator and targetBefore a server is able to initiate server I/O to the iSCSI storagesystem, it must be configured as follows:◆You have installed one of the following interface cards andrelevant drivers:• Supported iSCSI HBA cards that have a driver andconfiguration tool (for example, QLogic), or• Gigabit Ethernet Network Interface Cards (NICs) runningMicrosoft software that provides HBA functionality.365
