Dell 4MNKF

Overview

The Dell 4MNKF is a single-port Fibre Channel host bus adapter designed to deliver 16 Gb/s data rates over a 16 GbE link, providing servers with fast and reliable access to external storage. It is ideal for environments that demand high bandwidth and low latency, such as virtualization, high-transaction databases, and media production. The adapter fits into a standard PCIe slot and connects directly to Fibre Channel switches or storage arrays via an SFP+ transceiver, ensuring seamless integration into existing SAN infrastructures.

Key features

• Single-port SFP+ connection enables direct attachment to Fibre Channel storage networks for efficient data transfer.
• MicroSD-based flash memory stores firmware and configuration settings on the card, simplifying updates and host migrations.
• Dust-resistant design protects critical optics and circuitry, enhancing reliability in typical data center environments.
• Supports high-throughput and low-latency communication, reducing backup windows and accelerating large dataset transfers.
• Easy installation into standard PCIe slots minimizes downtime during upgrades or expansions.

Key specs

• Data rate: 16 Gb/s Fibre Channel over 16 GbE
• Interface: Single-port SFP+
• Form factor: Standard PCIe card
• Firmware storage: MicroSD flash memory
• Design: Dust-resistant for enhanced durability

Connectivity and compatibility

This adapter connects directly to Fibre Channel switches or storage arrays using the SFP+ transceiver, making it compatible with existing SAN setups that support 16 Gb/s Fibre Channel. Its PCIe form factor ensures compatibility with a wide range of server motherboards that have available PCIe slots.

Ideal uses and environments

The Dell 4MNKF is well suited to data centers and enterprise environments where high-speed, predictable storage access is critical. It supports workloads such as virtualization, media production, and high-transaction databases that require consistent bandwidth without network congestion. It also serves as a practical upgrade path for organizations moving from 8 Gb/s Fibre Channel links to higher speeds with minimal disruption.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
