M2-S6920-4S Data Center Switch

The M2-S6920-4S is a new-generation fixed switch released by Micas Networks for AI and other application scenarios. It is highlighted by its high performance and high density.

Designed based on a single 12.8T chip, the M2-S6920-4S switch provides up to 128 x 100GbE physical ports in the space of 4 RU. It can be used with the M2-S6920-4S series switches to establish small to super-large spine-leaf architecture data center networks.

This product offers adjustable L2/L3 resource allocation capabilities for different types of networks and monitoring and O&M functions (such as INT/Telemetry/ZTP) for automatic monitoring and O&M. Used with the M2-S6510 series switches, it can support the construction of lossless networks and can be applied to service scenarios that require lossless transmission, such as AI training or HPC.

Highlights

Non-blocking Hyperscale Data Center Networks

Provides 128 x 100GbE ports

Data Center Overlay Networking

Supports VXLAN to meet the data center overlay networking requirements and enables the establishment of a logically layer-2 network on the layer-3 network.

RDMA-based Lossless Ethernet

Supports the RDMA feature and enables the establishment of lossless, low-latency data center Ethernet.

Cloud Networking Ready

Shared 32MB Buffer with burst absorption
Up to 288K MAC and 168K Host entries

Automated O&M/Monitoring Network

Supports In-band Network Telemetry to enable active pushing of switch status based on gRPC.
