Storage
Storage is a collection of technologies, systems, and devices designed for storing, managing, and accessing data in IT infrastructures. The term storage refers both to physical data carriers and to hardware and software solutions that provide reliable and scalable data storage.
Storage is a fundamental component of any IT system. It is used to store operating systems, applications, databases, backups, user files, and machine-generated data. Infrastructure performance, fault tolerance, and scalability directly depend on the architecture and characteristics of storage.
The role of storage in IT infrastructure
The primary function of storage is to ensure secure and accessible data storage with defined requirements for speed, reliability, and capacity. In corporate and cloud environments, storage must support high workloads, concurrent access by multiple systems, and protection against data loss.
Modern storage systems are tightly integrated with servers, networks, virtualization platforms, and cloud environments, forming a unified data storage infrastructure.
Types of storage
Depending on architecture and use cases, several main types of storage can be distinguished:
- Direct Attached Storage (DAS) – storage directly connected to a server
- Network Attached Storage (NAS) – file storage accessible over a network
- Storage Area Network (SAN) – a dedicated network for block-level data access
- Object Storage – object-based storage for scalable handling of large volumes of data
Each storage type is designed for specific tasks and differs in performance, scalability, and access methods.
How storage works
Storage systems provide data writing, storage, and reading using various media such as HDDs, SSDs, and NVMe. To improve reliability, redundancy, replication, and data integrity control mechanisms are used.
Storage management is performed through software interfaces and management systems that allow configuration of storage pools, access policies, fault tolerance levels, and performance characteristics.
Storage in corporate and cloud environments
In corporate data centers, storage is used to host business-critical systems, databases, and virtual machines. In cloud environments, storage is provided as a service and can be dynamically scaled according to workload requirements.
Hybrid and distributed storage architectures allow local storage systems and cloud resources to be combined into a single data storage environment.
Advantages of modern storage systems
Key advantages of modern storage solutions include:
- scalability in capacity and performance
- high reliability and fault tolerance
- support for different types of workloads and data
- integration with virtualization and cloud platforms
- centralized management and automation
At the same time, selecting storage requires careful consideration of access speed, latency, reliability, and total cost of ownership.
FAQ
Storage refers to systems and devices used to store data and provide access to it.
