Save space in your server room by adding a real CCR2004… inside the server itself! This unique product combines a simple 2x 25 Gigabit PCIe Ethernet adapter with the impressive features of a full-fledged router.

By default, the PCIe interface will appear as four virtual Ethernet interfaces. Two interfaces in passthrough mode to the 25G SFP28 cages. The other two virtual Ethernet-PCIe interfaces are bridged with the Gigabit Ethernet port for management access. The user can configure all interfaces and settings freely since we are running a fully functional RouterOS here.

To make this CCR device work as a NIC, a new Passthrough mode was implemented. Essentially, a FastForward FastPath mode can also pass hardware link statuses.

This NIC can achieve wire speed (100Gbps) with Jumbo frames. It ensures that in most server setups this CCR network card will not be the bottleneck.

With 4 GB of RAM, 128 MB of NAND storage, and a powerful quad-core ARMv8 64-bit CPU, this device can handle a lot: firewalls, user management, and access control for home media and file servers, and even some traffic control in data centers – without the need for a separate router.

This form factor does have some limitations that you should be aware of. The CCR NIC card needs some time to boot up compared to ASIC-based setups. If the host system is up before the CCR card, it will not show up among the available devices. You should add a PCIe device initialization delay after power-up in the BIOS. Or you will need to re-initialize the PCIe devices from the HOST system.

We are excited to see your unique use cases for this unconventional device: a simple high-speed networking card combined with a powerful Cloud Core Router.
