MikroTik CRS812-8DS-2DQ-2DDQ-RM – 100G Cloud Router Switch with 8x25G SFP28, 2x40G QSFP+, 2x100G QSFP28

Overview

The MikroTik CRS812-8DS-2DQ-2DDQ-RM is engineered for ultra‑high speed environments where reliable core and aggregation switching matters. Housed in a compact 1U rackmount chassis, this switch blends dense port options with advanced routing capabilities to support data centers, service providers, and large enterprise networks without sacrificing footprint or energy efficiency.

Rather than a single‑purpose device, it offers a versatile port mix designed to scale with evolving workloads. The unit ships with 8x 25G SFP28 ports for high‑density access and aggregation, plus 2x 40G QSFP+ ports for streamlined uplinks. For even loftier throughput, it includes 2x 100G QSFP28 ports to connect core devices or upstream networks. This mix enables flexible topology planning, minimizing the need for additional intermediate switches while preserving rack space.

Layer 3 hardware offloading stands out as a practical enhancement. In busy networks, hardware‑assisted routing can help process large traffic flows at line rate, reducing CPU load and leaving more room for policy enforcement, VLANs, ACLs, and monitoring tasks. The hardware offload capability is complemented by RouterOS v7, which brings a broad feature set for enterprise‑grade management and visibility.

With RouterOS v7 and a Level 5 license, administrators gain access to advanced routing, VLAN segmentation, firewall rules, traffic monitoring, and policy control. The combination of hardware acceleration and a rich software stack can help operators tailor performance to their specific needs while preserving simplicity in daily management.
