Cisco CQ211L01-48H8FH Switch Data Sheet

Overview

Cisco CQ211L01-48H8FH Switch

The Cisco^® CQ211L01 switch is a high-performance and high-density switch designed for cloud data center applications. It offers 48 ports of 100 Gigabit Ethernet (GE) Dual Small Form-Factor Pluggable (DSFP) and 8 ports of 400 GE Quad SFP Double Density (QSFP-DD) connectivity, delivering a total of 8 Tbps of switching capacity. The switch enables scalable and secure multitenant cloud environments. It also leverages the Cisco Silicon One^™ architecture, which provides a unified silicon platform for both routing and switching applications across different market segments. The switch is powered by the Cisco Silicon One Q211L ASIC, which is based on the 7-nm process technology, offering lower power consumption, higher performance, and greater integration. It is ideal for data center leaf and top-of-rack deployments, where it can provide high-speed connectivity and low-latency forwarding for cloud applications and services.

Silicon innovation with the Cisco Silicon One ASIC

Cisco Silicon One is a groundbreaking routing silicon architecture that exceeds the 10-Tbps benchmark for network bandwidth without compromising route capacity, forwarding performance, or feature flexibility. The first-generation Q100 ASIC achieves 10.8 Tbps of throughput using 16-nm process technology. The second-generation Q200 ASIC boosts performance to 12.8 Tbps using 7-nm process technology, while the new P100 ASIC further increases performance to 19.2 Tbps using the same technology. These ASICs provide high-scale routing and deep buffering without requiring off-chip memories, which can reduce data path bandwidth due to frequent memory access. This is made possible by the innovative internal architecture of Cisco Silicon One, which includes an on-chip High Bandwidth Memory (HBM) that significantly improves performance while reducing power consumption.

The Cisco Silicon One Q211L builds on the ground-breaking technology of the Cisco Silicon One Q200L, Q201L, and Q202L to provide a full-duplex, standalone switching processor with efficiency and flexibility enabled by Cisco Silicon One and 7-nm technology. It supports 80x 100 GE, 40x 200 GE, 48x 100 GE plus 8x 400 GE, and 20x 400 GE leaf and Top-of-Rack (TOR) switches and can be used to build fixed form-factor switches ideally targeted for data center leaf and TOR applications.

The Cisco Silicon One architecture offers numerous benefits, including a unified architecture across multiple markets that greatly simplifies customer network infrastructure deployments, a unified SDK across market segments and applications that provides a consistent point of integration for all applications across the entire network infrastructure, high-performance routing and switching silicon that achieves line rate at small packet sizes, power-efficient routing and switching silicon enabled by the power efficiency of 7 nm and the Cisco Silicon One architecture, a large and fully unified packet buffer, switching efficiency with routing features and scale that addresses the requirements of service providers’ and web-scale providers’ routing and switching applications, a run-to-completion network processor that provides feature flexibility without compromising performance or power efficiency, and P4 programmability that allows for rapid feature development.

System design innovation

The Cisco CQ211L01 switches are based on the Cisco Silicon One ASIC, which delivers industry-leading performance, power efficiency, and programmability. These switches support up to 48 ports of 100 GE DSFP plus 8 ports of 400 GE QSFP-DD in a compact one-rack-unit (1RU) form factor and support lower speeds such as 10 GE, 25 GE, 40 GE, and 50 GE. This provides customers with the flexibility to design networks that can accommodate various types of servers, storage devices, and network appliances. The switches offer wire-speed Layer 2 and Layer 3 switching with low latency and jitter, as well as advanced features.
