What type of NIC can be used for the external network on a Dell PowerScale F600 node?

The Dell PowerScale F600 node offers flexible front-end (external) network connectivity options to integrate into various data center environments. The standard configurations include dual-port Network Interface Cards (NICs) that support either 10 GbE using SFP+ transceivers or 25 GbE using SFP28 transceivers. This allows customers to leverage existing 10 GbE infrastructure or upgrade to higher-speed 25 GbE networks for more demanding workloads.

A. 1/10 GbE is incomplete. While 10 GbE is supported, the F600 does not typically use 1 GbE for primary external connectivity, and this option omits the 25 GbE capability.
B. 10/100 GbE is incorrect. The F600 supports 100 GbE, but not as a combined option with 10 GbE in this format. The primary options are 10/25 GbE or 40/100 GbE.
D. 25/40 GbE is an uncommon pairing. The F600 supports 25 GbE and can support 40 GbE, but they are typically offered as separate options or paired as 40/100 GbE, not 25/40 GbE.

- Dell PowerScale F600 Specification Sheet, "Front-End Networking" section. The document explicitly lists "2 x 10GbE (SFP+) or 2 x 25GbE (SFP28)" and "2 x 40GbE (QSFP+) or 2 x 100GbE (QSFP28)" as available options. Option C is a valid and common configuration.

- Dell PowerScale F200, F600, and F900 Hardware Guide, "Front-panel features and indicators of the F600 node" section. This guide details the network ports, which are SFP28, supporting up to 25GbE.
