The High-Speed link (HSL) OptiConnect feature provides high-speed system-to-system communication between managed systems.
The HSL OptiConnect feature can be used only for communications between i5/OS® logical partitions on IBM System i5™ or eServer™ i5 models. If you must enable communications with an IBM System p5™ or eServer p5 model, use an Ethernet connection instead of the HSL OptiConnect feature.
To use the HSL OptiConnect feature on a logical partition, you must install OptiConnect for OS/400® (a priced optional feature) on each i5/OS logical partition that is to use HSL OptiConnect. If you use the Hardware Management Console (HMC) to partition your managed system, you must also check the partition profile properties for each i5/OS logical partition that is to use HSL OptiConnect and ensure that the Use High Speed Link (HSL) OptiConnect option is selected on the OptiConnect tab. For more information on changing partition profile properties, see Changing partition profile properties.
You can use both the HSL OptiConnect feature and the virtual OptiConnect feature on the same i5/OS logical partition. If multiple paths are available between i5/OS logical partitions, the OptiConnect software automatically selects the virtual OptiConnect path instead of the HSL OptiConnect external path.
The HSL OptiConnect feature requires only standard HSL cables to connect the systems to one another. No additional hardware is required.
