Data center networking is the process of establishing and interconnecting the entire physical and network-based devices and equipment within a data center facility. It enables a digital connection between data center infrastructure nodes and equipment to ensure that they can communicate and transfer data between each other and on an external network or Internet.
- provides a highly scalable, high-density network foundation for today’s most demanding data center and cloud environments. Customers can start small—with as little as one rack—and expand the fabric to include up to 128 racks. Whether a data center has 300 or 6,000 servers, which can significantly cut operations overhead and enable faster application delivery.
- Simplified network topology—You can combine multiple devices into a topology that appears to the larger network as a single device, and then manage the device from a single IP address.
- The using of VXLAN data plane encapsulation allow you to stretch Layer 2 connection over an intervening Layer 3 network, while providing network segmentation like a VLAN, but without the scaling limitation of traditional VLANs.
Benefits of using VXLANs:
- Theoretically create as many as 16 million VXLANs in an administrative domain.
- Enable migration of virtual machines between servers in separate Layer 2 domains by tunneling over Layer 3 networks.
- No need to use STP to converge the topology
-All links can be used.
-Traffic can be load balanced.
