To add a second HPE Synergy frame to an existing logical enclosure, the customer needs to join the new enclosure to the management ring and modify the Logical Interconnect Group (LIG) to add the new frame. This process involves:
* Joining the New Enclosure to the Management Ring: Physically connect the new Synergy frame to the existing frames using the Frame Link Modules (FLMs). This extends the management network, allowing HPE OneView to discover and manage the new enclosure.
* Modifying the Logical Interconnect Group (LIG): Update the existing LIG to include the interconnect modules of the new frame. This ensures that network configurations are consistent across all frames in the logical enclosure.
* Adding the Enclosure to the Logical Enclosure: In HPE OneView, add the new enclosure to the existing logical enclosure. This integrates the new frame into the managed environment, allowing server profiles and resources to be utilized seamlessly.

High Available when the modules are in different frames. Redundancy is when the modules are in the same frame.

When utilizing 25Gb connectivity for all HPE Synergy compute nodes, the maximum number of frames that can form a single logical enclosure is 3. This limitation is due to the bandwidth and port constraints associated with 25Gb interconnect modules. Logical enclosures define the management and networking domains within the Synergy infrastructure, and adhering to these limits ensures optimal performance and reliability.
