i5/OS™ represents iSCSI attached xSeries® and IBM® BladeCenter™ servers similar to the way it represents IXS and IXA attached xSeries servers. However, the iSCSI technology requires additional i5/OS objects and configuration information that were not required for IXS and IXA attached xSeries servers. Since iSCSI attached servers are connected to the iSeries™ system with an Ethernet network (rather than the system bus/HSL attachment that is used with the IXS and IXA), additional configuration information is required to identify and communicate with the xSeries or IBM BladeCenter server on the network. In addition, since iSCSI attached servers can coexist with other systems on the Ethernet network, security of communications and data flows between i5/OS and the iSCSI attached servers can be a concern. The following diagram shows how iSCSI attached servers are represented by i5/OS.
Figure 15 shows key i5/OS objects as well as key hardware components that are used for iSCSI attached xSeries or IBM BladeCenter servers when network security is not used.
See the following sections that describe the objects in Figure 15 :
For information about the i5/OS objects used for iSCSI attached xSeries and IBM BladeCenter servers with network security, see Figure 16.
