A network-attached storage device, or NAS for short, is a specialised type of computer designed to provide file-based data storage services to a computer network. In contrast to a standard desktop or laptop PC, which typically stores its data on an internal hard drive, a NAS device contains one or more large-capacity drives that are accessible by all devices on the network. This makes it an ideal solution for centrally storing and sharing files among multiple users. But what exactly is a NAS and how does it work then must visit : https://stonefly.com/blog/network-attached-storage-appliance-practicality-and-usage

1. Network Attached Storage (NAS)
Appliance: Practicality and Usage
Network attached storage provides a scalable, flexible and dynamically
upgradeable infrastructure which meets the needs of the fast growing
businesses which require exponential growth in the capacity of storing and
managing the mission critical unstructured big data.
What is a Network Attached Storage Device?
If you’re confused about “What is NAS storage” here’s a brief explanation:
A network attached storage device is a file level data storage infrastructure which
offers virtually unlimited scalability. It consists of appliance nodes which are not just
the storage drives but a lot more than that. These are servers which have the ability
to store and manage the data along with the ability to provide data services and
features in order to assure data protection and security.
It’s a network attached file level data storage. You can store, access and share data
in the network attached storage appliance via a configured network using NAS
storage protocols: NFS/CIFS and SMB. The network attached storage device is the
best option for simplified and effective storage of unstructured big data.
What is Network Attached Storage Used for?

2. Wondering what is NAS storage used for? To summarize it, a NAS network storage
is used for unstructured data storage. This can be surveillance videos, files,
backups, snapshots, emails, etc.
The network attached storage is very handy for HPC (High Performance Computing)
requirements. NAS appliances can be effectively used for requirements like video
data editing and retention in broadcasting environments, video data storage for law
enforcement agencies, record maintenance and data analytics for Finance industry,
secure and cost effective storage for Healthcare industry etc.
Network attached storage can also be very useful in managing the video surveillance
data, media and entertainment industry and also hi tech data coming from body worn
cameras which are generating may be more than any other form of video data.
These are some of the leading use cases of network attached storage.
Cloud Storage vs NAS Storage
Cloud based solutions are mostly preferred because of three reasons: Scalability,
Data Accessibility and Cost Effectiveness.
When comparing cloud storage solutions with enterprise network attached storage
solution; the first question that comes to mind is: “Why should I purchase an
appliance instead of setting up storage in a cloud?”
The main benefit is the speed that comes with the network attached storage device
and the lack of a third party.

3. StoneFly’s SSO™ (Super Scale-out) network attached storage delivers scale-out
capabilities that enhance performance along with the increased storage space. The
SSO™ network attached storage device also supports scale-up for simplified storage
environments.
As far as accessibility is concerned, the data stored in the storage appliance can be
accessed remotely as long as the appliance is kept on. In order to do so, the IT
teams can configure a VPN (Virtual Private Network) / RDP (Remote Desktop
Protocol) to enable access to stored data. This delivers the same kind of data
accessibility and device independency as cloud based services.
NAS vs RAID – Not an Either/Or Decision
Redundant Array of Independent Disks (RAID) is a hardware configuration used to
improve disk performance, and setting up fault-tolerance. Storage expansion units
that come with a built-in hardware RAID controller are often referred to as RAID
storage arrays or RAID arrays.
RAID leverages data redundancy across multiple drives, depending on the RAID
level, to prevent data loss even if a drive or drives fail.
For more about RAID, read What is RAID?
As mentioned above, NAS storage provides scalable file storage to devices
connected to the network. While both NAS and RAID are storage technologies, you
shouldn’t have to choose between them. A reliable NAS storage infrastructure
should have integrated RAID controller to ensure high availability and business
continuity.
RAID levels are denoted by a number and determine the performance and
redundancy of the NAS RAID storage. High end systems for larger organizations
offer a plethora of RAID options that storage administrators can use to meet their file
storage capacity, performance and data protection requirements. For example,
StoneFly SSO NAS storage, depending on the appliance series and model, are
configured with high-performance 12Gb SAS hardware RAID controller with RAID
Cache Battery backup that supports RAID Levels 0, 1, 3, 5, 6, 10, 30, 50 and 60.

4. The Role of Network Attached Storage Device in
Work Environment
Network attached storage technology fits perfectly in an office environment that
depends on effective data sharing between different workstations and/or
departments. Data mobility empowers all processes and slowly contributes to the
productivity of the team and the company.
For instance, consider a broadcasting environment. There are multiple sources of
image and video data. With a network attached storage device, all of this data can
be easily channeled into the desired storage location. It’ll be easier for the resource
management department to collect and manage this data. Then, when it comes to
the editing part, the video editor won’t have to wait for the data; they’ll access the
same storage location and start working. Evidently, the appliance plays a central role
in such an environment.
This role of network attached storage technology in inter- and intra-team
collaboration makes it very attractive for companies focused on leveraging teamwork
for productivity and profitability.
Advantages of NAS Storage
Centralized File Storage Management – Consolidate and simplify file storage and
sharing with a centralized NAS storage. By setting up access protocols, you can
make sure that all departments and teams have access to important data
seamlessly.
Complete Control of Infrastructure – With an on-prem NAS storage, you maintain
complete control of your digital assets as opposed to cloud storage where you rely
on the CSP and don’t know exactly where the data is stored.
Customize Your Private Cloud – Customize the CPU, system memory, network,
and storage capacity of your NAS storage to build a private cloud as per your needs
and budget.
Hybrid and Multi-Cloud Storage – Leverage cloud connect services to combine the
performance of on-prem NAS storage with the scalability of the cloud to set up a

5. hybrid and multi-cloud storage environment. Facilitate diverse workloads with a
unified file storage solution.
Automate Data Management – With data services such as automated hot/cool
tiering, automate data transfers between hot-tier storage hosted on SSDs, to cold tier
storage using SAS/SATA so that you can ensure effective NAS storage with
minimum IT staff intervention and no human error.
Data Protection with Network Attached Storage
Device
Immutable Snapshots
Immutable storage snapshots make sure that the snapshots taken once, cannot be
edited, deleted or changed. Once a snapshot is taken, it cannot be overridden and it
assures data protection.
Write-Once Read-Many (WORM) Volumes
WORM stands for Write Once Read Many. It means once data has been written to
WORM volumes, it cannot be edited or modified for the defined retention period.
However, it can be read as many times as required. These immutable WORM
storage volumes makes sure that even if a ransomware gains access to the
corporate network, the critical data stored in them is protected and secure.
Built-in Anti-Malware and Anti-Ransomware
StoneFly’s network attached storage is equipped with anti-malware and
anti-ransomware features to make sure that the mission critical data is safe and
secure from the cyber-attacks which have become a very common phenomenon
