with Intel 82599 Chipset X520-DA2 10G PCI-E X8 Ethernet Server Adapter

In this review the focus is on a practical, server-grade 10Gb/s adapter aimed at small datacenters and advanced workstation builders. The Jeirdus card uses the Intel 82599ES chipset and provides two SFP+ LR ports, which is the single biggest reason to consider it: reliable, hardware-level Ethernet performance and compatibility with long-reach 10km LR optics. For anyone upgrading from 1GbE or replacing failed server NICs, this card delivers stable 10Gb connectivity and broad OS support without unnecessary extras.

Key Features

• Dual 10Gb/s SFP+ ports: Two SFP+ LR transceivers included let servers connect to 10km single-mode fiber right out of the box for long-distance links.
• Intel 82599ES controller: The original Intel chipset provides proven stability and support for I/O virtualization, improving server reliability under load.
• Full-height and low-profile: Ships with both bracket types so it installs in standard and compact server chassis without extra parts.
• Wide OS compatibility: Drivers are available for Windows Server editions, desktop Windows, Linux and VMware ESX, easing deployment in mixed environments.
• 10Gb/s throughput: PCI-E x8 interface sustains high bandwidth for storage, virtualization or aggregation tasks in small server racks.

Who It's For

The card is aimed at IT professionals, homelab builders and small business administrators who need dependable 10Gb networking for virtualization hosts, storage servers or aggregation switches. Its inclusion of SFP+ LR modules makes it especially useful where fiber distance or existing single-mode fiber runs are required.

Those who should look elsewhere include users who need copper 10GBase-T RJ45 ports, or casual desktop users who will never benefit from server-grade features like I/O virtualization. If you require vendor support bundles or enterprise warranty integration, check procurement channels that supply those services.

Pros & Cons

Pros

• Includes two 10Gb/s SFP+ LR transceivers, enabling immediate single-mode fiber connections up to 10km.
• Equipped with the Intel 82599ES chip, offering stable performance and broad driver support across common server OSes.
• Comes with both full-height and low-profile brackets for flexible installation in different chassis.
• PCI-E x8 interface delivers the bandwidth expected for virtualization and storage aggregation.

Cons

• Does not include 10GBase-T copper ports, so additional cabling or transceivers are required for RJ45 networks.
• No manufacturer-provided customer reviews included with the product information to indicate field experience.

Our Verdict

The Jeirdus adapter with the Intel 82599 chipset is a pragmatic choice for anyone needing reliable 10Gb fiber connectivity without complications. It bundles LR SFP+ modules and both bracket sizes, making installation and long-reach fiber links straightforward. For virtualization hosts, storage nodes or edge servers that already use fiber, it represents strong value for the price and avoids the pitfalls of lesser third-party controllers.

Frequently Asked Questions

Are the SFP+ LR transceivers compatible with other equipment?
Yes, the included 1310nm LR transceivers are standard SFP+ modules rated for 10km single-mode fiber and should work with compliant switches and optics.

Will this card work in a consumer desktop?
It will work in desktops with a free PCI-E x8 or x16 slot, but desktop users who need RJ45 copper should choose a 10GBase-T adapter instead.

Does the card support virtualization features?
Yes, the Intel 82599ES controller supports I/O virtualization features that help improve performance in virtualized server environments.
