Which one do I need?
Choose QM8700 when you need an onboard subnet manager. Choose QM8790 when a subnet manager already runs on a server or another managed switch; it costs less for the same 40 ports. QM9790 for 400Gb/s NDR with ConnectX-7 adapters. CS8500 leaf and spine blades are replacement or expansion parts for an existing CS8500 chassis, a liquid-cooled director that holds up to 800 HDR ports when fully populated. For EDR 100Gb/s, see Switch-IB EDR.
Adapters: ConnectX. Cables and optics: DAC, AOC and transceivers.
