Network Attached Storage (NAS) is a dedicated file storage device that provides centralized data storage over a network and access to multiple users and client devices. It is a standalone device that connects directly to a network and can be accessed through a web-based interface or File Transfer Protocol (FTP). Network Attached Storage devices are designed to be easy to set up and manage, making them an excellent choice for both personal and business use.
What is Network Attached Storage (NAS)?
NAS is a type of storage technology that allows multiple users to store and access files from a centralized location. It is essentially a computer dedicated to file storage and sharing, with its own operating system and hardware components. Network Attached Storage devices are typically equipped with one or more hard drives or solid-state drives (SSDs) for data storage and can be configured with various RAID levels for data redundancy and performance.
What is Network Attached Storage used for?
Network Attached Storage is used for various purposes, from personal data storage to enterprise-level data management. Some common uses of NAS include:
Network Attached Storage enables users to work together more efficiently and access data in a much faster and more convenient way. It is an invaluable tool for collaboration and data-sharing. This is useful for distributed teams that require remote access or work in different time zones. With the NAS connected to a wireless router, it becomes much easier for distributed workers to get the required files from any device or platform that has an internet connection. This helps them stay productive and reduces their dependence on particular devices in order to access their work. Organizations typically deploy NAS environments as storage filers or as a foundation for personal or private clouds.
To expand storage capacity, NAS devices are equipped with more or larger disks; This is known as a scale-up NAS.
NAS components and how they work
NAS devices typically consist of the following components:
A Network Attached Storage (NAS) relies heavily on a computer system with a CPU and memory. The CPU is in charge of running the Operating System, reading & writing data, managing user access & connecting with the cloud storage if needed. Where specialized computers or servers use a general-purpose CPU, dedicated equipment such as a NAS may use a specialized CPU designed for high performance and low power consumption in NAS use cases.
- Network interface
NAS devices connect to a network via a wired or wireless network interface, allowing users to access the device from anywhere on the network.
Every NAS must provide physical storage, usually in the form of disk drives. Drives may include conventional magnetic HDDs, SSDs, or other non-volatile memory devices, often supporting a mix of different storage devices. Network Attached Storage can support logical storage organization for redundancy and performance, such as mirroring and other RAID implementations – but it is the CPU, not the disk, that handles such logical organization.
Like a traditional computer, the OS organizes and manages the NAS hardware and makes storage available to clients, including users and other applications. Simple Network Attached Storage devices may not expose a specific OS, but more sophisticated NAS systems may employ a discrete OS such as the Netgear ReadyNAS, QNAP QTS, Zyxel FW, or TrueNAS Core.
Why is choosing the right NAS important?
Choosing the right NAS device is crucial for maximizing storage and efficiency. There are various factors to consider when selecting a NAS device, including:
- Capacity: The capacity of a NAS device determines how much data it can store. It’s essential to choose a device that can accommodate your current and future storage needs.
- Performance: The performance of a NAS device is determined by factors such as processor speed, memory, and network interface. It’s important to choose a device that can handle the demands of your data storage and access requirements.
- RAID configuration: NAS devices can be configured with various RAID levels, which provide different levels of data redundancy and performance. It’s important to choose a RAID configuration that fits your needs and budget.
- Scalability: It’s important to choose a NAS device that can be easily expanded as your storage needs grow.
NAS product categories
There are various NAS product categories available in the market, each designed for specific use cases. Some common NAS product categories include:
- High-end or enterprise
The higher end of the market is driven by organizations that need to store and share large amounts of file data, including virtual machine (VM) images. Enterprise Network Attached Storage devices can scale to provide petabytes of storage, serve thousands of client systems, and provide instant access and clustering capabilities. The clustering concept overcomes the drawbacks associated with traditional NAS.
For example, a device assigned to an organization’s primary storage location creates a potential single point of failure. Redundancy is usually accomplished through some form of duplication – copying data to more than one storage device or storage subsystem.
NAS midmarket solutions are ideal for companies that have numerous customer systems that require several hundred terabytes of data to be stored. However, these devices cannot be clustered, which can lead to file system silos when multiple NAS devices are needed.
- Low-end or desktop
NAS low-end systems provide local file storage solutions for both home users and small businesses. With these systems, they may store up to several terabytes of data for individual clients. The market is moving toward a cloud NAS service model, with products such as Burst’s SoftNAS Cloud NAS and software-defined storage (SDS) from legacy storage vendors.
NAS deployments for business
File sharing and collaboration: NAS devices can be used as a centralized file-sharing platform, allowing multiple users to access and collaborate on files from a single location.
- Backup and disaster recovery: NAS can be used as a backup solution, providing an additional layer of protection for critical data. In case of a disaster, NAS can be used to restore data quickly and efficiently.
- Virtualization storage: NAS devices can be used as storage for virtualization platforms such as VMware and Hyper-V, providing a cost-effective and scalable storage solution.
- Video surveillance storage: NAS devices can be used to store and manage video surveillance footage from security cameras, providing a centralized and secure storage solution.
- Media streaming: NAS devices can be used to stream media files such as videos and music to connected devices, providing an easy and convenient way to access media files.
What’s the Future of Network Attached Storage?
As data storage and management continue to evolve, the future of NAS looks bright. Some of the trends that are likely to shape the future of NAS include:
- Increased adoption of cloud-based NAS: As more businesses move their data storage to the cloud, the demand for cloud-based NAS solutions is likely to increase.
- Integration with AI and machine learning: NAS devices are likely to integrate more with AI and machine learning technologies, providing advanced data management and analysis capabilities.
- Increased focus on data security: With the increasing amount of data being generated and stored, data security is becoming more critical than ever. NAS devices are likely to focus more on providing advanced security features and capabilities.
- The continued growth of video surveillance storage: As the use of video surveillance continues to grow, the demand for NAS devices to store and manage video footage is likely to increase. NAS devices will need to provide high storage capacity and performance to meet the demands of video surveillance applications.
Network Attached Storage is a versatile and cost-effective option for data storage and access. With its centralized management and easy access, it provides an efficient way to manage data for personal and business use. By understanding the basics of NAS, its components and how they work, the different NAS product categories, its deployment for business, and the future of network attached storage, you can make an informed decision about choosing the right NAS device for your needs.
