Data Center Fabric FAQs
What is a data center switch fabric?
A data center fabric is a system of switches and the interconnections between them that can be represented as a unified logical entity. The fabric allows for a flattened network architecture in which any attached server or storage node can connect to any other server or storage node. Similarly, any switch node can connect to any other switch, server, or storage node.
What is the difference between a data center fabric and a traditional network?
The term “fabric” describes how switch, server, and storage nodes connect to all other nodes in a mesh configuration, evoking the image of tightly woven fabric. These links provide multiple redundant communications paths and deliver higher total throughput than traditional networks.
Are there different types of data center fabric architectures?
Yes, there are both proprietary architectures and open, standards-based fabrics, such as EVPN-VXLAN.
What is EVPN-VXLAN?
This type of fabric is an overlay network that sits on top of an IP-fabric underlay. It enables the extension and interconnection of Layer 2 data center domains and placement of endpoints (such as servers or virtual machines) anywhere in the network, including across multiple data centers.
What data center technology, solutions, and products does Juniper offer?
