Shared Storage

Shared Storage is a data storage approach in which multiple servers or virtual machines (VMs) have access to common storage resources. The shared storage is typically presented as a single, logical volume to the servers or VMs. This allows them to access and store data centrally, without having to rely on local storage devices.

Advantages of Shared Storage

Shared storage offers several advantages over local storage, including:

• Improved Data Availability: Shared storage makes data available to multiple servers or VMs, ensuring high availability in case of a server or VM failure.
• Simplified Data Management: Centralized storage simplifies data management tasks such as backup, recovery, and replication.
• Increased Data Security: Shared storage can be managed with robust security measures to protect data from unauthorized access.
• Cost Optimization: Shared storage can reduce hardware costs by eliminating the need for local storage devices on each server or VM.
• Improved Performance: Shared storage can provide faster access to data compared to local storage, especially for I/O-intensive applications.

Types of Shared Storage
