Cluster Node Limit
Any GigaVUE-OS nodes can join other nodes in a cluster. The GigaVUE‑HC1, GigaVUE-HC2, GigaVUE-HC3, and GigaVUE TA Series nodes, including Certified Traffic Aggregation White Box (white box), can be included in the same cluster. Starting in software version 4.5, the maximum number of nodes supported in a cluster is 32. For details, refer to Cluster Scaling.
In addition, there is another independent limit, which is for the maximum number of line cards supported in a cluster, across all of the nodes in the cluster. This limit is determined by cost units. Cost units are based on the total number of line cards, line card types, and chassis type. Cost units measure the resources that a node needs in a cluster. The higher the cost unit, the more resources are needed to manage the node.
The following table has examples of line card and chassis types, and their cost units.

For example, if a GigaVUE-HC3 has one PRT-HC3-C08Q16 line card, one SMT-HC3-C05 GigaSMART line card, and one BPS-HC3-Q35F2G + PRT-HC3-X24 line cards, the cost units are 4 + 1 = 5.
Note: The cost unit for a GigaVUE-HC2 is always 1, regardless of how many modules are installed.
The cost unit maximum for the various nodes in the cluster is 255.
Therefore, the largest cluster supported is determined either by the maximum number of nodes (32) or by the cost unit maximum, whichever is reached first.
Cluster Scaling
The maximum number of nodes and map rules supported in a cluster is as follows:

When a Cluster is Configured with: |
Number of Nodes |
Maximum Map Rules |
|
Out-of-Band Cluster Management |
32 |
38000 |
|
Inband Cluster Management |
16 |
38000 |
The maximum number of map rules supported in a cluster apply to all nodes in the cluster including GigaVUE HC Series nodes: GigaVUE-HC3, GigaVUE-HC2, GigaVUE‑HC1, and GigaVUE TA Series nodes: GigaVUE-TA10, GigaVUE-TA40, GigaVUE-TA100, and GigaVUE-TA200, including Certified Traffic Aggregation White Box (white box).
Cluster Topologies
The following cluster topologies are supported:
| • | star |
| • | daisy-chain |
| • | tree |
