Leveraging vSAN for Highly Available Management Clusters : Introduction
   
Introduction
1.1 Overview
The VMware Cloud Provider™ Program is a global network of thousands of cloud service providers distributed across many regions who are offering or are planning to offer cloud and hosting services founded upon VMware cloud software platform. This platform allows them to provide world-class cloud services to their base of tenants and to build and package tailored offerings to win in their own market or location.
The Cloud Service Provider services are most commonly linked to a service plan that underlines the class of service being offered to the tenants. The flexibility of the software platform allows the integration of many different components. At the same time, complexity in a data center introduces questions about the reliability of each component and its influence on the overall solution.
The Cloud Management Platform is the management foundation for VMware Cloud Providers. It includes a critical set of integrated components to deliver a resilient environment for VMware vCloud® services consumers and to provide a powerful management instrument.
In such a delicate ecosystem, a critical component or a foundation pillar of every architecture that requires top priority care in design is the underlying storage infrastructure. The infrastructure is designed and built to provide the performance and reliability required for designated service levels.
The use case depicted in this paper covers the scenario of a hyper-converged infrastructure built with VMware vSAN™ to address the availability needs of a management cluster.
The key benefits for the use of a hyper-converged infrastructure solution include the following:
Infrastructure cost reduction by means of replacing dedicated traditional storage devices
Reduced management complexity thanks to the native integration of vSAN and VMware vSphere®
Granular policies to tune performance and storage consumption based on a per-workload basis
