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

There are different types of shared storage technologies available, including:

• Network Attached Storage (NAS): NAS devices are dedicated storage appliances that connect to the network and provide file-level access to shared storage.
• Storage Area Networks (SANs): SANs are high-performance networks specifically designed for connecting storage devices to servers or VMs. They provide block-level access to shared storage.
• Cloud Storage: Cloud storage services provide shared storage over the internet. They offer scalable, on-demand storage that can be accessed from anywhere.

Applications of Shared Storage

Shared storage is widely used in various enterprise environments, including:

• Virtualization Environments: Shared storage is essential for virtualized environments, where multiple VMs share the same physical storage resources.
• High-Performance Computing (HPC): Shared storage provides the high I/O performance required for HPC applications.
• Data Warehousing: Shared storage is used to store and manage large datasets in data warehouses.
• Cloud Computing: Shared storage is a fundamental component of cloud computing platforms, providing centralized data access across multiple cloud services.
• Media and Entertainment: Shared storage is used for storing and managing large multimedia files in media and entertainment industries.

Learning Shared Storage

There are various ways to learn about Shared Storage, including online courses, books, and hands-on practice. Online courses provide a structured and convenient way to gain knowledge and skills in Shared Storage. They offer video lectures, interactive exercises, and assessments to help learners understand the concepts thoroughly.

By completing online courses on Shared Storage, learners can acquire valuable skills and knowledge, such as:

• Understanding different types of shared storage technologies
