Communications options for logical partitions

The types of communications options that you use depend on your business needs and the operating system you are running. You can establish interpartition communication using virtual Ethernet. For IBM System i5™ and eServer™ i5 server models, you can also use the HSL OptiConnect for high-speed system-to-system communication or the virtual OptiConnect to emulate external OptiConnect hardware providing a virtual bus between logical partitions.

• Virtual Ethernet
  This information provides an overview of virtual Ethernet and how AIX^®, i5/OS^®, and Linux^® logical partitions use virtual Ethernet to establish interpartition communication.
• High-Speed link (HSL) OptiConnect for i5/OS logical partitions
  The High-Speed link (HSL) OptiConnect feature provides high-speed system-to-system communication between managed systems.
• Virtual OptiConnect for i5/OS logical partitions
  The virtual OptiConnect feature provides high-speed interpartition communication within a managed system. The Virtual OptiConnect feature emulates external OptiConnect hardware by providing a virtual bus between logical partitions.
