Networking concepts

Hosted systems involve several different types of network connections.

Only iSCSI attached systems have the following connection types.

• Service processor connection
  This physical connection allows the hosting i5/OS™ partition to communicate with the hosted system's service processor.
• iSCSI network
  This physical network connects iSCSI adapters in the hosting i5/OS partition with iSCSI adapters in the hosted system.

All types of integrated Windows servers may have the following connection types.

• Virtual Ethernet
  This is a simulated Ethernet connection that does not require additional networking cards or cables. There are two types of virtual Ethernet
  • Point to point virtual Ethernet
    This connection provides general purpose communication between the hosted system and the hosting i5/OS.
  • Virtual Ethernet networks
    These are networks created between hosted systems, i5/OS partitions, and other partitions (such as Linux®).
• External networks
  These are the normal Windows networks which all servers use, created by networking through physical network cards controlled by the hosted system.
