When connecting a server with a 10 Gigabit Ethernet adapter to a switch, which cable type provides the best throughput?

Using a CAT6 straight-through cable ensures the best throughput when connecting a server with a 10 Gigabit Ethernet adapter to a switch. The CAT6 cable is designed to support higher frequencies and better data rates than its predecessors, like CAT5e. Specifically, CAT6 can handle up to 10 Gbps for distances up to 55 meters, making it suitable for 10 Gigabit Ethernet connections.

Additionally, the construction of CAT6 cable includes tighter twists and improved insulation, which reduces crosstalk and allows for better signal integrity over longer distances compared to CAT5e. This is crucial for maintaining high-speed data transfers, especially in environments where network traffic is heavy.

The other cable types mentioned provide either lower performance or are not suited for the requirements of 10 Gigabit Ethernet. For instance, while CAT5e can support gigabit speeds, it is not optimized for 10 Gigabit Ethernet, potentially limiting throughput in high-demand scenarios. Furthermore, rollover and crossover cables serve specific purposes in network configurations that do not apply to standard server-to-switch connections in this context.
