Overview
Bare-metal switches are driving the data center market as the high demands for cost-effective switch platforms and flexibility open hardware from service providers. With the upcoming era of 5G, the demands of Bare-metal boxes will continue to be strong. 5G advances the network applications which will need highly reliable and scalable infrastructure deployment.
Quanta Cloud Technology(QCT) provides a series of Bare Metal Switches, the QCT BMS product line, that addresses these changes in the data center market. To meet the requirements of high performance, high availability, fast scale-out, low latency performance, and continuous serviceability in data center applications, the QCT BMS product line offers high-performance and cost-effective open switch platforms.
The 100G High-density Modular Switch for Data Centers
QuantaMesh T7128-IXT is a high-density 4RU spine switch, supporting up to 12.8Tbps with 128 100G QSFP28 ports. It offers flexibility and cost-benefit of open networking with 8 slots of modular line cards in a single chip solution. It supports high-density interconnection for massive scale-out data centers and simplifies the spine-leaf networking tiers. The modular line cards allow service providers to have more flexibility on port configuration and help them smoothly migrate to 400G in the future.
With an assembly of high-speed, high density, and high bandwidth, QuantaMesh T7128-IXT is specifically designed for high-performance data center environments. Scalable packet processing and large shared buffer allow QuantaMesh T7128-IXT to provide lossless forwarding and dynamic load balancing. It can deal with the continuously growing workloads from 5G and AI applications. New instrumentation features improve network visibility and provide operators real-time network monitoring.
