datacenter
Overview
The increase in data center scale directly leads to a leapfrog upgrade in network complexity. Under the wave of new infrastructure, the demand for various digital infrastructure by enterprises and society has increased without decreasing. A highly efficient network that matches the scale of the data center is key to ensuring smooth flow of data and business within the data center. The first step in building an efficient network is to choose the right network architecture.
Challenges
How to achieve smooth evolution of network architecture?
How to achieve a server scale of 1-100k per cluster?
Benefits
Short path
The advantage of this architecture is that the data forwarding path is short, one hop across Leafs is reachable, and the path and latency have strong consistency Hardware level redundancy protection ensures business continuity and uninterrupted network.
Virtual network
VXLAN technology builds a virtual second layer network and creates a virtual tunnel in the IP network to achieve cross regional and cross data center data migration, and flexible resource allocation. Support EVPN-VXLAN, increase the number of tenants, and meet the identification and isolation needs between large-scale different networks. Support M-LAG virtualization technology, load sharing between links, and improve link reliability; The independent control surface supports independent device upgrades, achieving instant business upgrades and a seamless user experience.
Solution
Direct Connection for Improved Data Center Connectivity and Reduced Traffic
The core switch of the data center is directly connected to multiple secondary core node switches of the metropolitan area network, shortening the server platform path and reducing the traffic pressure on the backbone network.
Virtual Switching Unit (VSU) Technology for Consolidated and Independent Switch Functionality
The top of shelf TOR switch and dual core switch use VSU technology to virtualize two physically independent switches into one logically independent switch.
