If you have many users and many different machines that need to access the same data across a network, you probably have a NAS Array. A NAS Array or a Network Attached Storage Array is a file storage device similar to RAID storage, except it resides on the network, rather than be attached to a particular server. It is accessed through the Local Area Network or LAN and has its own IP address and its own operating system, usually Linux. More than just a file server, NAS arrays are often clustered and have the capacity for larger disks. They can be paired with cloud storage for backing up crucial files.
Advantages to Using NAS Arrays
Depending on your needs, the NAS Array can do many things that simple file servers cannot. High end NAS Arrays provide clustering for enterprise solutions. Not only do they allow rapid access to data and files, but they can offer virtual machine images (VM) and even act like another computer as a virtual machine. They can be paired with a Storage Area Network or SAN for greater storage access and flexibility. With high end and midlevel NAS Arrays, they can consolidate your file servers into a single point, making it easy to access without any special knowledge. Low end or consumer NAS Arrays provide the ability to share data across the network between home systems and smart objects as well as provide a good backup system for data. Like the high end and midlevel NAS arrays, the consumer versions require no special training. What’s more, all versions of the NAS Arrays are fast and relatively low cost for the job that they do.
Uses for Network Attached Storage Arrays
When businesses use NAS arrays, they normally use them in one of the following contexts:
As storage gateways which control the access to other storage devices, such as a SAN. This provides a greater ease of access and gives the users a single interface. What goes on behind the scenes is handled by the NAS Array.
As a fully integrated NAS system, where the NAS array is the storage system of choice.
As a clustered NAS system to provide fast access to data.
As a parallel file system which provides fast access to data to users with certain operating systems.
NAS RAID Devices
Network Attached Storage Arrays use RAID disks that are accessed by the Linux operating system onboard. The Linux operating system acts as an intermediary between the disks and the computers accessing the NAS. Types of RAID devices include:
RAID 0 disks: usually for low end or consumer level NAS Arrays, they are usually two disks which provides faster access than a normal disk.
RAID 1 disks: these are two disks where one is a clone of the other, providing backup should one fail.
RAID 5 disks: these are multiple disks that provide fast access to data and provide enough redundancy so that data can be recovered if one disk fails.
RAID 10 disks: these are multiple disks that provide fast access and cloning so that there is backup regardless of how many of the original disks fail.
We offer a risk-free evaluation–and even provide a UPS shipping label– to determine how much it will cost for us to retrieve your data from an NAS Array. We offer you a firm quote after the evaluation. You owe us nothing should you decide to not use us, or should we be unable to retrieve your data. We have more than 30 forensics and data recovery engineers who work in our data recovery lab, which is a certified clearoom. Gillware’s data recovery experts can recover your data for you.
