NETWORK CARDS

( number of products: 1305 )

Network Interface Cards – maximum throughput and server performance

A network interface card (NIC – Network Interface Card) is one of the most critical components of server infrastructure, determining the speed of data exchange between servers, storage arrays, and users. In virtualized environments, compute clusters, and backup systems, standard 1GbE solutions are no longer sufficient.

At Esus IT, we provide professional network adapters supporting 10GbE, 25GbE, 40GbE, and even 100GbE standards. Our offering includes solutions from industry leaders: Dell, Broadcom, HPE, Mellanox (NVIDIA), Synology, and QNAP, ensuring full compatibility with your hardware and maximum transmission reliability.

Network technology leaders in the Esus IT offering

Selecting the right NIC should be driven by server architecture and system requirements. In our portfolio you will find:

  • Mellanox (NVIDIA): The undisputed leader in the High-Performance Computing (HPC) segment. ConnectX series cards are valued for ultra-low latency and support for RDMA (RoCE) technology.
  • Broadcom: A manufacturer of reliable network chipsets, widely used in enterprise servers, with broad support for operating systems and VMware environments.
  • Dell & HPE: Dedicated network adapters (OCP, Mezzanine) designed for PowerEdge and ProLiant servers – full compatibility and integration with iDRAC/iLO.
  • Synology & QNAP: PCIe expansion cards (10GbE and Multi-Gigabit) for NAS servers, significantly increasing storage throughput.

Key parameters and technologies of enterprise NICs

By choosing a network card, you gain access to advanced features that enhance performance and security:

  • Connection standards: RJ45 (copper) as well as SFP+, SFP28, QSFP+ (fiber).
  • Virtualization support: SR-IOV enables direct assignment of resources to virtual machines.
  • iSCSI and FCoE: CNA adapters supporting both network and storage traffic over a single port.
  • Hardware offloading: TSO and Checksum Offload reduce server CPU load.

FAQ – Server network interface cards

1. Will an HPE NIC work in a Dell server?

It depends on the model. Standard PCIe cards are usually universal, while Mezzanine and OCP cards are designed for specific platforms. We recommend checking the part number (P/N).

2. When should I choose a 10GbE SFP+ card vs 10G Base-T (RJ45)?

SFP+ offers lower latency and power consumption – ideal for data centers. RJ45 is suitable for office environments where existing cabling infrastructure can be used.

3. Do Mellanox ConnectX cards support only InfiniBand?

No. Most models are VPI devices that support both Ethernet and InfiniBand, depending on configuration.

4. Why is it worth adding a 10GbE card to a NAS?

Standard 1GbE limits transfer speeds to around 110 MB/s. A 10GbE card enables speeds up to 1000 MB/s, significantly improving performance when working with large files and multiple users.
