HPE 779218-B21 Synergy 20G Interconnect Link Module device server

HPE Synergy 20G Interconnect Link Module

The HPE 779218-B21 is a satellite module for composable infrastructure. It extends fabric connectivity across multiple Synergy frames using a primary/satellite architecture. This device server consolidates data centre network connections and reduces the need for fixed interconnect ratios in each frame. It is built for organisations scaling rack-level network bandwidth.

Verify Synergy frame compatibility

Before ordering, confirm that your existing Synergy frames support satellite module expansion. The module requires a primary module with intelligent networking capabilities to extend connectivity to satellite frames. Check that your current fabric architecture can integrate a 20Gb satellite link for disaggregated resource pooling. Ensure rack-scale design aligns with this primary/satellite topology.

Sustained load consolidates connections across

Under continuous operation, the module maintains a fluid pool of network resources across multiple frames. It reduces hardware components at the aggregation layer while simplifying fabric management at scale. The satellite architecture delivers consistent 20Gb connectivity to compute modules without the port consumption of traditional top-of-rack switches. This design supports ongoing composable infrastructure demands.
