The MikroTik CRS812-8DS-2DQ-2DDQ-RM is a powerful managed switch designed for professionals who want to build high-speed network infrastructures at a cost-effective price. This device delivers revolutionary performance in data centers and enterprise networks thanks to its 400G QSFP56-DD ports. With a modern Marvell switch chip and a quad-core 2 GHz ARM processor, it supports all advanced routing, switching, and traffic management features of the RouterOS v7 operating system. Dual redundant hot-swap power supplies and 4 hot-swap cooling fans ensure uninterrupted operation and high reliability. Technically, this device offers a wide range of connectivity with 2x 400G QSFP56-DD, 2x 200G QSFP56, and 8x 50G SFP56 ports. Additionally, 2x 10G Ethernet ports provide compatibility with existing infrastructure. All high-speed ports can be broken out to lower speeds such as 1G/2.5G/5G/10G/25G/50G for flexible use. Equipped with 4 GB DDR4 RAM and 512 MB NAND storage, the device handles heavy network traffic seamlessly. With a maximum power consumption of 134W, energy efficiency is also considered. The CRS812-8DS-2DQ-2DDQ-RM is ideal for scenarios where intensive east-west traffic is critical, such as AI clusters, media workflows, and high-performance computing (HPC) environments. It can also be used as a top-of-rack or leaf switch connected to spine switches via 400G uplinks. Other prominent use cases include bridging 10G legacy systems with modern 50G interfaces in campus core networks or serving as a service provider aggregation node.
