NAS Device explained
NAS Simply are mini self contained PC’s designed specifically for centralized network-attached-storage.
They can also be used for Cloud storage, Online backup, or Cloud backup.
NAS has a very condensed Operating System, because its prime function is to backup and serve files. This Network Storage can be achieved through Wireless Networking, Home Networking or standard Cat 5 Networking.
NAS is attached to a small network either through a switcher, hub, or router; as its prime function is to act explicitly as a storage device.
Unlike our desktops, they are not designed for general computing as they do not have a huge collection of drivers and applications normally bundled with the Operating System and hardware.
NAS units have all of the elementary components of a computer, such as a CPU, RAM, and hard drive. Unlike traditional server functionality, they act solely to hold and share data files, music etc.
A NAS storage capacity will vary, depending upon individual needs and the amount and size of hard drives used for storage. So, the higher the amount of storage capacity required, the greater the cost of the NAS device. As NAS devices are geared to use multiple disks, it is commonly pre-configured in a RAID array of some level for redundancy and data protection.
NAS is easy to setup
A NAS server is easy to deploy in a network environment with very little knowledge of IT. A NAS unit is also independent of a network server so it doesn’t need to be configured as such.
You can assign a NAS anywhere in a network environment, be it a local office, server room or even a remote station.
Simply assign it an IP address and do a few environmental setting and you good to go.
Most NAS storage devices have setup wizards and software tools to make the procedure simple and user friendly.
What Disks does a NAS use?
NAS Storage devices generally support many different disc types, including SATA and standard ATA formats. Depending on the unit and Brand on offer, you may or may not be able to upgrade the drives.
NAS servers are often sold to only support one standard, either ATA or SATA. Should you build your own NAS, you have the choice of using what best suites your needs.
What is NAS RAID?
Redundant Arrays of Independent Disks or RAID setup is a very good idea. It permits you to backup your network data without storing it on the users’ PCs. This redundancy takes the task of storage and backup away from the individual PCs.
Most good NAS servers are pre-configured with RAID on a few levels allowing you to select the one best for your need. Once the RAID level is established all data will be written to the drives in that format.
What are the Pitfalls of NAS?
Depending on the number of PCs in a network trying to access NAS files, the device may have a problem keeping up, and will tend to slow down. Fewer users more speed.
NAS devices are independent from the server in your network, and they do run a bit more efficiently. This is because they don’t have the server’s load to take care of.
It is sometimes difficult to upgrade All in One NAS server. It is best to purchase one you know will handle your requirements and redundancy objectives.
What is NAS Supported Protocols?
NAS servers support many different transfer protocols. Commonly they support Internet file systems (CIFS) network file systems (NFS), and file transfer protocol (FTP). Your interface experience may vary, depending on the operating system and control system you select to use as access to the files.
How NAS connects to the Network.
802.11 has recently been incorporated into many NAS devices. This allows for wireless communication. Having said that; your access speed is as fast as your slowest connection. A NAS can also connected through a router or network switch using a CAT6 gigabit Ethernet Cable.
So I hope What is NAS shed some light on the subject for you.
