UDA Inter-System Connections
- The number of UDA uplinks is based on a node-to-uplink ratio of 6:1, with a minimum of three uplinks, based on the smaller of the systems being connected.
- Uplinks are connected switch to switch.
- Connect the UDA uplinks:
- For IntelliFlex systems containing a single pair of first-tier switches, connect the UDA uplinks to these switches in cabinet 1.
- For IntelliFlex systems containing multiple first-tier and a single pair of second-tier switches, connect the UDA uplinks to the second-tier switches in cabinet 2.
- For systems with multiple pairs of second-tier switches, evenly distribute the UDA uplinks to the second-tier switches for best performance.
- UDA connections between systems start at the highest switch port on both systems, and connect in descending order.
IntelliFlex Intra-System Connections
When second-tier switches are used, each clique is considered a group, and the cabinets in the group connect to the same first-tier switches. The number of uplinks to each second-tier switch depends on the number of second-tier switches in use, which depends on the number of nodes and cabinets.
- The two-tier BYNET switch topology enables large system sizes using 36-port switches.
- A single set of first-tier switches can support one to five cliques depending on clique size.
- Large systems are built with multiple first-tier switches interconnected with one to four sets of second-tier switches.
- Number of first-tier switch to second-tier switch uplinks is four for standard configurations.
- Second-tier 36-port switches can be installed in any cabinet that doesn't contain first-tier switches, default is Cabinet 2.
- Extremely large systems use the large switches in the BYNET cabinet as the second-tier switch.
- Processing nodes and Fabric-Attached Storage of a clique must be connected to the same first-tier switch.
- BYNET-attached PE nodes, TMS, and channel server nodes can connect to any first-tier switch.
| Number of Groups | Maximum Number of Nodes | Second-Tier Switches per Fabric | Uplinks (First-tier to Second-tier) Per Second-Tier Switch or Group |
|---|---|---|---|
| 1 to 9 | 117 | One 36-port switch | 4 |
| 10 to 18 | 234 | Two 36-port switches | 2 |
| 19 to 36 | 468 | Four 36-port switches | 1 |
