2. 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.

3. 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)

4. 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.

6. 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

7. NAS COMPONENTS
 Data reception component.
 Data interception component.
 Intermediate component.
 Data identification component.
These are components for configuring the NAS system.

8. 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

9. 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.

10. 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.

11. 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.

12. 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.
