NETWORK ATTACHED STORAGE (NAS)

WHAT IS NAS?• NAS is another computer in your network which you can ask for so and so

files.NAS unit understands file, folders and volumes.

• NAS is great for sharing files across users and servers

• Network-attached storage (NAS) is a type of dedicated files storage device that provides local-area network local area network (LAN) nodes with file-based shared storage through a standard Ethernet connection.

NAS• NAS is specialized for serving files either by its hardware, software or by its

configuration.

• NAS systems are network appliances which contain one or more storage drives, often arranged into logical, redundant storage containers or RAID.

• So basically, storage device which is directly attached to the network is called as Network Attached Storage (NAS)

INTRODUCTION• Originally NAS have the fixed disks, RAID arrays magnetic tape drives which are

exactly connected to the networks(Eg.SAN and other networks).

• NAS have its own LAN ip address for RAID configuration which is attached to the administrator computer that provide applications to network workplace clients.

• Nowadays electronic data rising frequently, so reliable data is a essential for small business.

• NAS device is most efficient way to centralize, share and protect information. Compared with DAS NAS solutions are easier to manage and improved performance.

NAS

NAS Framework• NAS device has a printed circuit board that removes TCP/IP functions from a

microprocessor. This high end version is able to serving the files in web browsing (e-mail) and huge file transfers between clients.

• RAID Arrays : One or more redundantly aligned independent hard disks, It will defend you from losing when an entity hard disk fails in the NAS device.

• Operating System : It is configured to present a computing background for network attached storage device

NAS COMPONENTS Data reception component.

Data interception component.

Intermediate component.

Data identification component.

These are components for configuring the NAS system.

MANAGING NAS• NAS Installation : Firstly we need to prepare our network then install the proper

operating system.

• Configuration : We can use different type of interfaces for NAS configuration.

• Interfaces : Console, Remote cell(rsh), comand line interface(CLI), HTTP(hypertext transfer protocol) and secure shell(ssh).

• Applications : NAS server need some applications for accessing data. These applications gives easy way to access their files from everywhere in the network environment.

• Examples :

Home directories

Email

Database

MAINTAINANCE For the reliable file sharing and access speed , NAS system need day to

day maintenance.

Such as, Analyzing and monitoring the performance. Hardware and software failures. Performance tuning. Storage management and user support.

However once we configured the NAS system then its very easy to maintain.

NAS

• A full featured OS is not needed.

• Stripped down OS is used.

• Example: FreeNAS or NAS4Free both open source NAS solutions designed for commodity pc hardware

• NAS designed to be a general purpose server

• NAS units usually do not have a keyboard or display.

• Controlled and Configured over the network often using a web browser.

FUTURE SCOPE

• In high confidential Zone many companies don’t use NAS system because sharing of data will become a problem.

• A Research & Development team continuously developing NAS system for future enhancement.

• This development makes NAS system more faster, flexibility and high functionality.

CONCLUSION

• Nowadays NAS is a new concept for the computer network. This concept used for development and growth of computer networks.

• This NAS system is becoming a initial part of the small scale industries and computing environment.
