Cisco VN-Link Virtual Machine Awareness Network and Storage Service

This article mainly gives you a detailed introduction of how Cisco VN-LINK network service settings, and for Cisco VN-LINK to give a detailed introduction, I believe you have read this article will be helpful to you.

Introduction

When companies invest in server virtualization to achieve integration, they also need to meet the needs of resource flexibility, high availability and energy efficiency. Virtual Machine (VM) portability, or real-time upgrades, are the core embodiment of the value of server virtualization. However, there are many obstacles to the further widespread adoption of this technology: 1) protection and Policy execution cannot be performed at the VM level, or the policy cannot be moved with the VM. 2) the VM cannot be viewed, making accounting and troubleshooting complicated. 3) the virtualized environment brings about institutional challenges.

Introduction to Cisco VN-Link

Cisco®The advent of VN-Link technology aims to solve the above problems. It bridges the server, storage, and network management domains to inform other environments of changes in one environment. For example, when a customer in a VMware ESX environment uses VCenter to start VMotion or move a VM from one physical server to another, this event is reported to the entire data center network and SAN, the corresponding network profile and storage services can be moved with the VM.

Cisco Nexus 1000V vswitch

Cisco Nexus™The Cisco VN-Link network service is first deployed on a V vswitch. It is designed for the VMware ESX environment. The vswitch is directly connected to the ESX management program and uses VMware's DVS technology to provide a tightly coupled operating environment.

VN-Link Storage Service

The VN-Link Storage Service adopts a mature smart array mode and is embedded in an optical fiber channel Array built by a Cisco MDS Optical Fiber Channel switch.

Advantages

Cisco VN-Link server virtualization technology helps ensure that all physical and virtual servers in the data center have consistent, policy-driven network features.

Policy-based VM Network Feature Configuration

Real-time and coordinated network, security, and storage service configuration
Unified and VM-centric management mode, supporting more efficient and flexible Server Management

Mobile VM Security and network policies

During a VMotion event, the policy moves with the VM and always provides network, security, and storage compatibility.
Protects DRS or real-time updates from discrete vswitches or port group configurations
Powerful business continuity, performance management, and security compliance mechanisms

Transparent, flexible, and consistent Management Mode

Adjust management and operation environments for VMS and physical servers in the data center
Maintain the existing VMware operating mode, and allow multiple administrators to define and apply network policies to the infrastructure at the same time.
Reduce TCO by implementing operational consistency and visibility in the Network
Provides flexible collaboration between servers, networks, security and storage teams, and supports the isolation, integration, and hybrid boundaries of various organizations) and team autonomy.
