  1. 1. NAS vs. SAN: Which Storage Strategy is Right for Your Small Business? Sponsored by:
  2. 2. Tony Giannini Enterprise Storage Specialist CDW Corporation
  3. 3. You KNOW you’ve got a data storage challenge when: <ul><li>You’re relying on individual users to back up data to external storage devices </li></ul><ul><li>You’re backing up all the company’s data on the file server </li></ul><ul><li>The CEO asks, “Why don’t we just get another server?” </li></ul>
  4. 4. Just some of the issues you’re constantly facing: <ul><li>Using servers as primary storage slows down applications and file serving and causes bottlenecks </li></ul><ul><li>Distributed storage among users compromises data security </li></ul><ul><li>Distributed storage is difficult to manage and track </li></ul><ul><li>Distributed storage is too reliant on end users </li></ul><ul><li>E-mail archiving </li></ul>
  5. 5. What are your biggest data storage challenges? <ul><li>□ Capacity </li></ul><ul><li>□ Performance </li></ul><ul><li>□ Time/effort required to manage </li></ul><ul><li>□ All of the above </li></ul>
  6. 6. You are not alone. A recent CDW Communispace survey of small businesses found: <ul><li>Data storage needs are greatly increasing. </li></ul><ul><li>Nearly two-thirds of small businesses have less than </li></ul><ul><li>2TB of available storage. </li></ul><ul><li>One-third anticipate needing at least 2TB more storage </li></ul><ul><li>in the next 1-2 years. </li></ul>
  7. 7. You are not alone. A recent CDW Communispace survey of small businesses found: <ul><li>Most organizations have a wide variety of servers deployed; </li></ul><ul><li>the vast majority have a file server and an e-mail server </li></ul><ul><li>that could be used for primary storage. </li></ul><ul><li>These organizations more than likely use </li></ul><ul><li>external hard drives, optical drives and USB flash devices </li></ul><ul><li>for basic storage needs. </li></ul>
  8. 8. Data Storage <ul><li>The simple math of Direct Attached Storage: </li></ul>As businesses grow, the cost and complexity of managing, backing up and replicating data grows as well.
  9. 9. What storage strategy is your business currently using? <ul><li>□ Direct Attached Storage (DAS) </li></ul><ul><li>□ Network Attached Storage (NAS) </li></ul><ul><li>□ Storage Area Network (SAN) </li></ul><ul><li>□ Other </li></ul>
  10. 10. What We’ll Cover Today <ul><li>NAS SAN </li></ul><ul><li>Network Attached Storage Storage Area Network </li></ul><ul><li>● What are the strengths of each? </li></ul><ul><li>● What are the cost implications? </li></ul><ul><li>● Which one makes the most sense for your organization? </li></ul>
  11. 11. Benefits of a Solid Storage Strategy <ul><li>● Efficient disaster recovery </li></ul><ul><li>● Simplified management </li></ul><ul><li>● Shared storage for hosts </li></ul><ul><li>● Simplified infrastructure </li></ul><ul><li>● Fewer storage resources needed </li></ul><ul><li>● Faster and better access to data from multiple users </li></ul><ul><li>● Greater compliance with laws and regulations dictating data storage and retrieval </li></ul><ul><li>● Hierarchical storage management </li></ul><ul><li>- Critical data easily accessible </li></ul><ul><li>- Stores archival data at lower cost </li></ul>
  12. 12. Are you budgeting for a NAS or SAN in 2010? <ul><li>□ Yes </li></ul><ul><li>□ No </li></ul><ul><li>□ Not sure </li></ul>
  13. 13. Upgrading Your Data Storage <ul><li>The first step: </li></ul><ul><li>Identify and evaluate your data and storage needs. </li></ul><ul><li>● How much data do you have? </li></ul><ul><li>● How much more do you foresee having? </li></ul><ul><li>● How critical is that data? </li></ul><ul><li>● What percentage truly needs to be redundant? </li></ul>
  14. 14. Network Attached Storage <ul><li>A storage device is connected </li></ul><ul><li>to a network instead of </li></ul><ul><li>a single machine so multiple users </li></ul><ul><li>can share files. </li></ul>
  15. 15. Network Attached Storage
  16. 16. Network Attached Storage <ul><li>● More reliable than Direct Attached Storage </li></ul><ul><li>● Easier to manage </li></ul><ul><li>● Easy to deploy and expand </li></ul><ul><li>● Ideal for businesses with lots of file and print servers and archive data </li></ul>
  17. 17. Network Attached Storage <ul><li>A file-based protocol, which enables </li></ul><ul><li>intelligent file management. </li></ul><ul><li>NAS is a less-expensive option than SAN </li></ul><ul><li>From a NAS appliance, you can easily back up to a tape drive or another disk </li></ul><ul><li>Support for common files systems — users of heterogeneous operating systems have equal access to data </li></ul>
  18. 18. Network Attached Storage
  19. 19. Storage Area Network <ul><li>A high-performance network </li></ul><ul><li>of storage resources. </li></ul>
  20. 20. Storage Area Network
  21. 21. Storage Area Network <ul><li>● Fast, easy to use and scalable </li></ul><ul><li>● Ideal for large databases and other demanding applications </li></ul><ul><li>- Microsoft SQL </li></ul><ul><li>- Exchange Server </li></ul><ul><li>● A good choice for organizations looking to consolidate storage from various servers and reduce backup windows </li></ul>
  22. 22. Storage Area Network <ul><li>Speed and scalability at the expense of simplicity. </li></ul><ul><li>Designed to move large blocks of data from one place to another over a Fibre Channel or iSCSI connection </li></ul><ul><li>Much faster than a NAS system </li></ul><ul><li>Because SAN operates on a separate network from the LAN, it can perform continuous data backup without taxing the entire network </li></ul><ul><li>SAN devices can be clustered to provide automated failover and to avoid a single point of failure </li></ul>
  23. 23. Storage Area Network
  24. 24. Combining NAS and SAN <ul><li>The best of both worlds: </li></ul><ul><li>NAS appliances with Fibre Channel or iSCSI connections can be integrated into a SAN </li></ul><ul><li>- The file-serving control and manageability of NAS </li></ul><ul><li>- The backup speed, availability and scalability of a SAN </li></ul><ul><li>Multiple NAS appliances can be clustered on a SAN to enable automated failover </li></ul>
