The Cisco Nexus 9000 Series organizations around the world recognize that changing application environments are creating new demands on the IT infrastructure that supports them. Application workloads are deployed on a mix of virtualized and non-virtualized server and storage infrastructure, requiring a network infrastructure that provides consistent connectivity, security, and visibility across a variety of cloud, virtualized, and cloud computing environments without operating system:
- The application instances are created dynamically. As a result, the provisioning, modification, and removal of application network connectivity must also be dynamic.
- Business units demand accelerated application deployments. IT departments must provide a shared IT infrastructure to address time-to-market needs and increase their return on investment (ROI).
- With organizations implementing a mix of custom, open source, out-of-the-box business applications, IT departments must manage both security and quality of service (QoS) for environments that support multi-tenancy.
- Applications have changed over time to a scalable, less monolithic, multi-node model. The IT infrastructure that supports this model must scale with the speed of business and support 10 and 40 Gigabit Ethernet connectivity.
Why Choose Cisco Nexus 9000 Series Switches?
Cisco Nexus 9000 Series Switches offer an exceptional portfolio of integrated, converged, and hyper-converged platform and network solutions to help customers meet these challenges. The capabilities of the next-generation Cisco Nexus 9000 series with Cisco Cloud Scale technology provide a multi-year advantage and sustained differentiation between Cisco and single-vendor proprietary point-product network providers and public cloud providers.
A key component of the Cisco ASAP (Analyze, Simplify, Automate, and Protect) data center, the Cisco Nexus 9000 Series provides a foundation that analyzes, simplifies, automates, and protects your entire modern data center like no other solution available.
Here are the top five reasons why the Cisco Nexus 9000 Series is the right choice as the foundation for today’s hybrid enterprise data centers.
As challenges become more diverse, Cisco offers customers a variety of custom application-specific integrated circuits (ASICs) and commercial silicon options in fixed and modular form factors with flexible Ethernet port configurations of 1, 10, 25, 40, 50 and 100 Gigabit. This flexibility offers investment protection and helps customers optimize their price-performance objectives in their network solutions for specific environments and use cases.
However, to deal with rapidly changing and increasingly complex hybrid data centers, customers should choose the Cisco Cloud Scale ASIC that powers the Cisco Nexus 9000 series.
This ASIC gives customers a minimum of a two-year advantage within the features they get compared to plain silicon products, providing greater scalability, deeper analytics and visibility, and better performance. Cloud-scale ASICs offer significantly greater scale and more features at an optimized price with capabilities including segment routing, group-based security policy, network service headers, and extensible virtual LAN (VXLAN) overlays with all the functions.
Cisco Cloud Scale Smart Buffers offer innovations to intelligently manage buffers and queue scheduling by identifying large and small flows and handling them differently.
– Dynamic Packet Prioritization (DPP): DPP prioritizes small flows over large flows, helping to make sure that tiny flows aren’t suffering from excessive queues to accommodate large flows.
– Fair Fall Approach (AFD): AFD introduces awareness of flow size and equity into the early fall congestion prevention mechanism.
Segment-based routing: The Cisco Nexus 9000 Series brings the facility of label switching to data center routing.
Simplified control plane: The Border Gateway Protocol (BGP) Ethernet Virtual Private Network (EVPN) control plane is used for VXLAN.
Simplified VXLAN operations: The Cisco Nexus 9000 Series supports VXLAN Operations, Administration, and Management (OAM) for easy troubleshooting and diagnosis.
In-service software update (ISSU): The Cisco Nexus 9000 Series provides a light-weight model for faster updates, reducing control plane downtime to but 3 seconds and eliminating data plane downtime.
Fiber Channel over Ethernet (FCoE):
FCoE reduces operational expenses (OpEx) and capital expenses (CapEx) by converging LAN and SAN environments.
Therefore, Cisco offers optimal cloud services and cloud economics through its Cloud Scale technology.
Open and extensible programmability:
Open Cisco NX-OS Software is the industry’s most extensible, open, and programmable network OS . It enables customers to programmatically provision and configure Cisco Nexus 9000 Series Switches through comprehensive and well-documented APIs offered by both Cisco and third parties. Customers can provision their switches using familiar tool integrations (such as Puppet, Chef, and Ansible) and have access to a strong API and community support.
This innovation is important for application developers, DevOps professionals, and other users preferring self-service infrastructure models to finish their projects, like application onboarding, more quickly and efficiently. With NX-OS, IT staff can meet these requirements by provisioning the network more quickly, reducing recovery time after failure, and gaining flexibility in an environment familiar to server administrators.
