Redunancy connection C7000 with HP ProCurve 6120XG

[Jakub7258]

Dear all,

In our data center are two HP ProCurve 6120XG Blade Switches in C7000 chassis connected to two Nexus 5000 switches.

Hp procurve switch no.1 is connected to Nexus switch no.1 with one link (blue) port20 on HP ProCurve 6120XG-1

HP procurve switch no.2 is connected to Nexus switch no.2 with one link (blue) port20 on HP ProCurve 6120XG-2

Current connection is without red links, only with blue links.

I'd like to add another two links (red) for 100% redunancy.

What is the best way for best redunancy connection and what do I need to configure on the HP switches ?
