Maršrutizatorius Mikrotik CCR2004-1G-2XS-PCIe

A smart and easy way to create 25gigabit networks if you want to save space in your server room.
The card combines a simple 2x 25gigabit PCIe Ethernet adapter with the impressive capabilities of a full-featured router.

By default, the PCIe interfaces appear as four virtual Ethernet interfaces. Two interfaces in 25G SFP28 cage pass-through mode.
The remaining two virtual Ethernet-PCIe interfaces are bridged with a Gigabit Ethernet port for management access.
The user can configure all interfaces and settings freely by using a fully functional RouterOS installation.

To make this CCR device work as a network card, a new Passthrough mode has been implemented.
Basically, this is a FastForward FastPath mode that can also forward hardware link states.

With 4 GB of RAM, 128 MB of NAND and a powerful quad-core 64-bit ARMv8 processor, this device can do a lot:
firewalls, user management and access control for home media and file servers, and even some data center traffic control (without the need for a separate router)

However, this form-factor comes with some limitations that you should keep in mind.
Compared to ASIC-based assemblies, the CCR NIC needs some time to boot up.
If the host system is booted before the CCR card, it will not appear among the available devices.
You should add a delay in the BIOS to initialize the PCIe device after power-up. Otherwise, you will have to reinitialize the PCIe device from the host system.

Included with the activated RouterOS license L6 Controller.
