What Is Unified Storage?

Unified storage is a game-changing technology for businesses and networks that need simplified, consolidated storage. It combines block and file storage into a single, easily scalable, and easy-to-manage system.

Let’s explore what unified storage is, how it works, and its potential advantages and downsides.

What Is Unified Storage?

Also known as multiprotocol storage, unified storage allows multiple types of data to be stored in the same device. It combines block and file storage protocols, such as iSCSI, NFS, and SMB, into a single platform, making it easier for IT administrators to manage and maintain their storage infrastructure because they have it all in one place. With unified storage, users can access their data from different applications and platforms via a single interface, which helps streamline workflows and reduce storage complexity.

What Is a Unified Storage Architecture?

A unified storage architecture is the design and framework that underpins the functionality of unified storage systems. It uses a single storage pool to store data, which can be allocated dynamically to different storage tiers based on the data's usage. The architecture also includes features like data deduplication, compression, and encryption, which further enhance the efficiency and security of the storage system.

Block Storage vs. File Storage vs. Unified Storage

Block storage is a type of storage that manages data in large, fixed-sized blocks, typically used for databases, virtual machines, and backup data. File storage, on the other hand, organizes data into files and folders, typically used for documents, images, and video files. Unified storage combines both block and file storage protocols into a single platform, providing a more versatile and flexible storage solution.

How a Unified Storage Architecture Works

A unified storage architecture works by consolidating different types of storage into a single system. It provides a single point of management for all storage-related tasks, including provisioning, allocation, backup, and recovery. It also uses advanced features such as thin provisioning, snapshots, and cloning to reduce storage waste and improve efficiency. Furthermore, a unified storage architecture can scale horizontally and vertically to meet the growing demands of data-intensive applications and workloads.

Components of Unified Data Storage

A unified data storage system contains several components, including storage controllers, storage arrays, network interfaces, and management software. The storage controllers manage the storage access protocols and data services, while the storage arrays contain the physical storage devices such as hard drives and solid-state drives. Network interfaces connect the storage system to the network, and management software provides a GUI or command-line interface for administrators to manage and monitor the storage environment.

Support for Multiple Storage Protocols

One of the key benefits of unified storage is its support for multiple storage protocols. This allows users to access their data from a variety of platforms and applications, regardless of the underlying storage technology. For example, a user can access their files from their desktop PC, laptop, or mobile device, without worrying about the file format or location. Unified storage also supports multiple operating systems, including Windows, Linux, and Mac OS.

Benefits and Advantages of Unified Storage

Unified storage offers several benefits and advantages to businesses and networks. It’s simplified and cost-effective, for one. It also offers scalable and flexible architecture and improved data protection and security. Let's take a closer look at each of these benefits.

Simplified and Cost-effective

By consolidating different types of storage into a single platform, unified storage simplifies storage management and reduces operational costs. It eliminates the need for separate storage systems for different types of data, reducing the time and effort required to manage and maintain them. Additionally, unified storage can help businesses save money on storage hardware and software licenses, as they no longer need to purchase separate systems for block and file storage.

Scalable and Flexible

A unified storage architecture is designed to scale both horizontally and vertically to meet the growing demands of data-intensive applications and workloads. It uses tiered storage, thin provisioning, and other techniques to optimise the use of available storage resources, increasing the system's capacity and performance. A unified storage architecture is also flexible enough to support different storage technologies, including hard disk drives, solid-state drives, and cloud storage.

Potential Downsides of Unified Storage

While unified storage offers many benefits, it also has potential downsides that businesses should consider. Two of the most significant downsides are performance and complexity issues and vendor lock-in.

Performance and Complexity Issues

Unified storage can be more challenging to manage and maintain than separate systems for block and file storage. This complexity can lead to performance issues, especially when dealing with data-intensive applications and workloads. Furthermore, unified storage may require additional resources, like network bandwidth and processing power, to handle the diverse storage workloads effectively.

Vendor Lock-in

Another potential downside of unified storage is that it can be challenging to switch vendors or migrate to different storage technologies once you have committed to a particular system. This can result in higher costs and being locked in to specific hardware and software.

Unified Storage Vendors and Providers

There are several vendors and providers that claim to provide unified storage solutions, including NetApp, Dell, and Hewlett Packard. Each vendor offers a different set of features, performance, and pricing options. However, historically these legacy storage systems have only offered unified storage via compromises and retrofits leveraging architectures built for the era of spinning disk. They lack native multi-protocol support for block and file on all-flash storage. 

Pure Storage® FlashArray™ is the first truly unified block and file platform of its kind. Not only do you get a global storage pool that can be used across block and file, but you also can expand it non-disruptively on the fly with unlimited file system sizes. FlashArray also offers high performance, scalability, and flexibility, making it an excellent choice for businesses and networks with demanding storage needs. 


Unified storage is a critical component of modern storage solutions, offering businesses and networks a versatile, flexible, and cost-effective storage architecture. 

By consolidating different types of storage into a single platform, unified storage simplifies storage management, reduces costs, and improves data protection and security. 

However, it’s essential to evaluate the potential downsides of unified storage, such as performance issues and vendor lock-in, before committing to a particular vendor or solution. With careful consideration and planning, unified storage can be an excellent investment for businesses and networks looking to optimise their storage infrastructure for the future.
