The shared storage design includes design decisions for vSAN and secondarystorage.

Well-designed shared storage provides the basis for an SDDC and has the following benefits.

  • Prevents unauthorized access to business data

  • Protects data from hardware and software failures

  • Protects data from malicious or accidental corruption

Follow these guidelines when designing shared storage for your environment.

  • Optimize the storage design to meet the diverse needs of applications, services, administrators, and users.

  • Strategically align business applications and the storage infrastructure to reduce costs, boost performance, improve availability, provide security, and enhance functionality.

  • Provide multiple tiers of storage to match application data access to application requirements. 

  • Design each tier of storage with different performance, capacity, and availability characteristics. Because not every application requires expensive, high-performance, highly available storage, designing different storage tiers reduces cost.
