Figure 7. Multiple iSCSI attached servers
A single iSCSI HBA for iSeries™ can host multiple xSeries® or IBM® BladeCenter™ servers. This concept is illustrated in Figure 7.
Figure 7. Multiple iSCSI attached servers
Each hosted system requires at least one iSCSI HBA to be installed in the server. Each iSCSI HBA in the hosted system is connected over an Ethernet network to the iSCSI HBA for iSeries. This network can be a physically secure or isolated network when a physically secure model is implemented. In i5/OS™ each of the hosted systems or remote systems are represented by a set of objects. These objects are described in more detail in Software concepts.
Each hosted system must have a service processor installed for remote discovery and power management. Multiple service processors can be connected to a single iSeries LAN adapter over an external network.
