- 1. NETWORK ATTACHED STORAGE Network Attached Storage Network Attached Storage
- 2. Overview Network Attached Storage – or NAS – has quickly become the preferred method of adding storage to any network NAS can be used for file sharing, on-line local or remote back-up, internet and intranet data storage and much much more Why you should be reviewing your storage needs?
- 3. User demands make increased storage capacity essential network users today have an increasing appetite for large files of many kinds which quickly eat up storage capacity - large graphics files, imaging applications, engineering CAD/CAM files, large databases, internet growth and legal need to store e-mails office suite and other data-intensive applications and much more…
- 4. … plus new technology increases the need for more storage Bandwith of LANs has increased at least seven-fold over recent years Huge amounts of data are shuttled around your LAN, campus or over remote networks at high speed
- 5. The old choices.. Until recently Network Managers had only two choices: Add more disk drives to an existing general-purpose file server OR Add a new general purpose server
- 6. The new solutions now available Add a new network file-sharing technology called Network Attached Storage (NAS) OR depending on your user needs Implement a Storage Area Network (SAN)*
- 7. Network Attached Storage Connects IDE or SCSI hard disks to Ethernet networks Designed for file sharing and data storage in local area networks Is simple to install, easy to use and highly reliable No PC required, no cumbersome set-up or administration Virtually maintenance free Flexible and scaleable Complements your file server
- 8. File Server vs NAS Difficult to install & maintain Extra CPU/IO server load Requires separate additional network operating system, adding greater cost & complexity Often needs additional client software as well as cabling Complex machines often mean higher cost & lower reliability Users pay for CPU, NIC, monitor, keyboard, NOS, application licenses, extra RAM, storage etc. Limited expansion options Plug & play” installation, easy management Reduced cost of ownership and ease of use No extra software needed Simplified product, low number of parts = low cost & high reliability Users pay only for specific hardware & software needed for their requirement Solves a specific application!

- 16. Adding a Network Attached Storage (NAS) device to your system is simple Example of a NAS Device
- 17. LAN Storage Accessed over TCP/IP File Sharing using standard NFS,CIFS,HTTP, FTP etc File System handled by NAS unit File System How NAS works
- 18. Benefits of NAS storage Administrator : Extreme ease of installation No client software Uses existing security features within Unix and NT. Remote management Low cost of acquisition & virtually no maintenance User : User experience is exactly the same as accessing a standard file server Supports multiple network operating environments and various protocols at the same time Security : NAS can include RAID functionality for security of data Existing client back up software will work with a NAS device
- 19. Benefits of NAS to Organizations Low Cost Performance Scalability High-Availability Security Reliability Manageability and Interoperability
