https://community.hpe.com/t5/bladesystem-general/62-10gb-stacking-possible/m-p/732#M33757 Is it possible to have greater than 10Gb stacking connectivity between any two enclosures in a Virtual Connect domain? If so, what ports would be used?

The cheapest way is to use the 10Gb copper cables with built in SFP connectors.

If I were to create a four enclosure domain with VC Flex-10 modules in interconnect bays 1 & 2 in all enclosures and create stacking links as described by HP with the CX4 ports, would I then be able to later increase the stacking bandwidth (to 20Gb) between any two enclosures by adding an additional 10GB SFP+ link from one of ports X2-X6?

According to the doc "HP Virtual Connect for the Cisco Network Administrator": "An administrator could purposefully add additional stacking links to provide shorter stacking link paths between modules. For example using the scenario above, the administrator could add an additional stacking link between module 2 and module 8. If added, module 2 could send frames towards the active uplink on module 8 using the directly connected stacking link to module 8. Purposefully adding additional stacking links is not a common practice since each module’s latency of 3.8 microseconds is so low."
