Ultra-low Latency Top-of-rack Switch for Data Center Bridging Deployments
Data centers today are facing a new generation of challenges. Virtualization and data center consolidation have imposed higher bandwidth demands on data center networks. The competitive business landscape has also pushed forward the need for faster application deployments. Next-generation data centers need to provide the efficiency, flexibility and availability to facilitate business agility and competitiveness.
The ZyXEL XS3900-48F is a high-density top-of-rack (ToR) switch designed to facilitate fast and modularized application deployments in next-generation data centers. It supports DCBX, 802.1Qaz (ETS) and 802.1Qbb (PFC) protocols, and offers 10GbE and 40GbE connectivity to provide high bandwidth and ultra-low latency performance for converged networks and virtualized applications. The 48 fixed 10GbE SFP+ ports can also support 1GbE SFP transceivers for added flexibility and easy network transitions.With redundant and hot-swappable fan trays and power supply modules, the XS3900-48F offers the redundancy, reliability and availability for non-stop services.
Ultra-low latency performance
The ZyXEL XS3900-48F is a high-density ToR switch designed to provide ultra-low latency performance for Data Center Bridging deployments. It features forty-eight (48) 10GbE SFP+ ports and four (4) 40GbE QSFP+ uplinks for high-performance and scalable networking. Built with non-blocking switching architecture, the XS3900-48F delivers 1.28 Tbps switching capacity and 952.4 Mpps forwarding rate, with an additional 9 MB packet buffer. The XS3900-48F offers ultra-low latency IP switching performance on all ports, making it the ideal choice for ToR deployments in data centers.
Data center optimized service quality
The ZyXEL XS3900-48F is optimized to deliver the service quality required in demanding converged data center networks. This high-performance ToR switch offers enhanced management of data center traffic with support for Data Center Bridging Exchange (DCBX), 802.1Qaz Enhanced Transmission Selection (ETS) and 802.1Qbb Priority-based Flow Control (PFC) protocols. The switch can discover and communicate with other DCB-enabled network devices with the DCBX protocol, and utilize PFC and ETS to manage, pause and schedule the behavior of different traffic to avoid traffic congestions, ensure lossless operation, and guarantee bandwidth for critical applications.
Modular and flexible rack-by-rack deployment
To meet the demands of rapidly changing business operations, data centers today need to be more agile and flexible than ever before. Purpose-built for top-of-rack deployments, the ZyXEL XS3900-48F facilitates modular data center deployments, which offer fast and easy rack-by-rack server changes or upgrades. Not only do top-of-rack data center designs require less cabling infrastructure and offer cleaner cable management, they also enable quicker deployment and easier scaling of network applications.
