VC Stacking Links - Bonding 10Gb links together

[Alisdair Philp]

We are building racks based on the multi-enclosure stacking guide for two enclosures. We are provisioning networking via a 20Gb LACP bundle in the top chassis and another 20Gb LACP bundle into the bottom chassis using 10Gb fibre SFPs.  We are stacking using the SFP based HP 0.5m SFP+ 10GbE Copper Cable 487649-B21 between chassis units.

Question? If we connect modules with multiple stacking links, does VC bundle these together to form another 20Gb link between the chassis units? ie if we connect two HP 0.5m SFP+ 10GbE Copper Cables between Chassis 1 / VC 1 and Chassis 2 / VC 1 and then another two between Chassis 1 / VC 2 and Chassis 2 / VC 2 will VC bundle them together?

Virtual Connect Ethernet modules support 10GBASE-CX4 stacking cables 0.5 m to 7 m (1.64 ft to 23.00

ft). The 1000BASE-T links can also be used as stacking links of up to 100 m (328 ft). Ports with different

connector types can be aggregated if the link speed is the same. For example, CX4 and SFP+ ports both

running at 10G can be aggregated to provide enhanced throughput for the stacking link.
