The Cisco Nexus Switches make it simpler to connect and manage disparate data center resources with software-defined networking (SDN).
The Cisco Unified Fabric of the Nexus Switches, first announced in January 2008, was designed to provide all servers with access to all network and storage resources eliminating the need for parallel storage and computational networks. The purpose was to simplify deployments and make sure of consistent networking across physical, virtual, and cloud environments.
Cisco Nexus Features
The Cisco Nexus switches enable Business and IT Agility providing flexible, highly available fabric that supports dynamic resource allocation, changing traffic patterns, complex workloads, and scalability within and across data centers.
Consistent policies and services that are built directly into the fabric and aware of the virtualized environment simplify the delivery and management of network functions in converged, virtualized and cloud environments and by using consolidated, multi-protocol solutions, with a single point of management for the LANs and SANs, minimizes disruptions to existing infrastructure and operations.
All switches in the Nexus family run the modular NX-OS firmware and operating system which combines the company’s storage area network (SAN) OS from its SAN switching lines with its IOS routing code. This modular design allows for fault containment and automatic recovery, so processes can be started, stopped, and upgraded, even without human intervention.
By leveraging Cisco ACI and leaf and spine architecture, Cisco Nexus switches can provide a flexible and reliable infrastructure for enterprise data centers.
Nexus Switches provide a quick and dependable switching infrastructure aimed at giving users the high performance needed for the virtualized environment in next-generation data centers. They offer continuous system operations and transport freedom, I/O consolidation, as well as the delivery of advanced networking capabilities, such as high availability, hitless In-Service Software Upgrades (ISSU), etc.
Cisco Nexus Switch License
About Cisco Nexus Switch License, all switches in this family support recently announced Cisco smart licenses which allows all licenses to be managed from CSSM which is a central platform. Moreover, Cisco offers licensing solutions for highly-secure network infrastructure like Cisco Nexus PLR license which simply register all product instances with no connectivity to the internet.
