Lenovo ThinkSystem QLogic QL45214 Flex 25Gb 4-Port Ethernet Adapter

Four SFP28 ports at 25GbE on a mezzanine card are the offer of the Lenovo ThinkSystem QLogic QL45214 Flex 25Gb 4-Port Ethernet Adapter, part number 7XC7A05844. The controller is a QLogic QL45214, and the title's Flex label ties it to the Flex-style compute nodes it was designed for.

Mezzanine adapters connect straight to the compute node, so they only fit the platforms they were built for. Verify the node model before you order, because this is not a card you can drop into a regular PCIe slot.

Four ports let a single node carry several networks, such as production, storage, backup and management. The ports run at 25GbE and use SFP28 connectors, though in a chassis-based system the external connection often goes through a switch module, so check how your enclosure wires the ports.

Like-for-like replacement is the simplest route to keep firmware and driver stacks unchanged.

The 7XC7A05844 is available new, refurbished and used. New and refurbished units carry 1 year or 3 years of warranty. Used units carry 90 days. Send the quantity and node model to request pricing.
