Autonegotiation between 1GbE, 2.5G bE, 5GbE, and 10GbE provides the necessary backwards compatibility required for a smooth transition and easy migration to 10GbE.
The X550 is a low-cost option for deploying 10GbE in your data center because it uses CAT6 and CAT6A cabling - standard cabling for many data centers. Copper cabling's flexible reach from 1 meter to 100 meters also supports Top of Rack (ToR), Middle of Row (MoR), and End of Row (EoR) network architectures.
