Why NAS? Most Small Business rely on individual HDD s in laptops, desktops and servers No or non regular backup What if the server HDD or the HDD of a single computer fails? 14. 4. 2009 3
Why NAS? Secure your business data Share files & collaboration Backup and version control Disaster recovery Redundancy You can loose programs or the OS You can not loose financial records, source code, customer & supplier data,.. => this is mission critical for any business with electronic records 14. 4. 2009 4
NAS some Acronyms NAS = Network Attached Storage JBOD = Just a Bunch Of Disks RAID = Redundant Array of Inexpensive Disks (Redundant Array of Independent Disks) CIFS -Common Internet File System, successor of SMB protocol with enhanced functionality, Microsoft NFS Network File System, Sun (MAC, Unix, Linux, Novell) FTP File Transfer Protocol 14. 4. 2009 5

Redundant Array of Inexpensive/Independent) Disks (RAID) Factors RAID is a method for using multiple hard drives (in an array) to share data. Used for backing up files or hard drives by writing additional copies of the data across other drives. There are various RAID levels. Each provide different benefits. Description Best Use Usable Storage Fault Tolerance vs. JBOD Read Speed vs. JBOD Write Speed vs. JBOD RAID 0 Striped Temp Data 100% Same Faster Faster RAID 1 Mirrored Operating Systems Log Files 50% Can lose 2 Faster Slower RAID 5 Striped + Parity User Data Operating Systems Log Files (N-1) / N N = # disks Cal tolerate loss of 1 disk Faster Slower RAID 10 Mirrors of Striped High Load Database 100% 14. 4. 2009 18 50% Can tolerate loss of 1 disk Slower Faster JBOD Just a Bunch Of Disks Temp Data -- -- --

Sales Pitch why NSS Disk-less chassis design available => build custom solutions Support for JBOD, RAID 0, 1, 5, 5+spare, 10 => choose the right disk tax and protection/performance level for your customer On disk file encryption => address vertical markets, such as health care, law offices, Virtualization, combine multiple NAS devices to one logical, incl. MSDFS => build bigger NAS to meet customer demands Hot swap drives and RPSU support => high up-time MS-Domain Support => easy integration into a MS Domain Easy Management and options, cable analysis, LACP, VLAN, 802.1p, 802.1q => easy to set-up and maintain 14. 4. 2009 23
How to back up a NAS? Assume a NAS with 1TB of storage Floppy Disks? You would need 694,000 pcs > 1,000 meter > 2 years CD? You would need 1,428 pcs ~ 1.75 meter DVD? You would need 250 pcs ~ 0.35 meter => the only way to backup a NAS locally is another NAS => good opportunity for SP s to provide backup 1 RU 14. 4. 2009 24

Why do we need backup software? Every computer.. Runs anti-virus... Runs a fire-wall... Has our work-critical documents... Has our life-critical pictures, email, media. Every computer... But virtually none run backup Less than 1% backup. More than 1 billion PC s alive. More than 170 million new each year. Majority (93%) of corporate data now lives on the edge. Most computers are laptops. Compliance risk. End-user data value is now very high (business and consumer) But virtually none run backup... 14. 4. 2009 27
