Understanding san ( storage area network )
- 2. SAN Definition SAN components Fibre Channel Network Host Bus Adapter (HBA) Enterprise Storage A SAN is an intelligent network environment in which storage resources are deployed and managed independently of any single server . . . .
- 3. SAN Components Fibre Channel (FC) Network Fibre Channel Network - Host Bus Adapter (HBA) - Enterprise Storage A high performance (200 MB/sec) redundant network made up of fibre channel switches for deploying and sharing enterprise resources
- 4. SAN Components Host Bus Adapter (HBA) Fibre Channel Network - Host Bus Adapter (HBA) - Enterprise Storage Similar to a SCSI adapter card or a LAN network interface card (NIC), provides the server with a FC interface to the SAN
- 5. SAN Components Enterprise Storage Fibre Channel Network - Host Bus Adapter (HBA) - Enterprise Storage Any storage device with FC interface that is interoperable with the switches, HBAs, servers and server operating systems in the network
- 6. User Requirements Increased storage capacity Support for multiple storage/server architectures Continuous/High availability Cross-platform solutions Why SAN ?
- 7. Why SAN ? User Requirements Support higher levels of I/O activity Higher performance backup/restore Data sharing Secure Assets
- 8. SAN Benefits Performance FC @ 200MB/sec vs SCSI @ 40MB/sec Availability Redundancy, non-disruptive upgrades Scalability Add or re-deploy storage as needed
- 9. SAN Benefits Flexibility New, advanced SAN devices can easily be added as older devices wear out or become obsolete Backup/restore/archive Move data at FC speed vs LAN (up to 100x) Centralized storage management Manage SAN as a single entity (shared resources)
- 10. SAN Benefits Reduced costs Storage management, capacity overhead Data sharing Access to any data on SAN Secure Assets Multiple layers of security to ensure data integrity
- 11. SAN Benefits Remote Replication Geographical data replication for disaster recovery SAN to SAN Copy Copy data from disk to disk geographically using SAN technology

- 13. SAN Storage – Performance Connectivity Hundreds of 2-Gbit/sec Fibre Channel interfaces allow thousands of MB/sec aggregate data rates Reliability/Availability Fully redundant components allow for non-disruptive maintenance and upgrades Scalability 28 TB disk storage now installed and growing 28 GB cache, can scale to 32 GB cache memory 9960 Storage
- 14. The Network – Brocade Switches Performance/Connectivity Hundreds of 2-Gbit/sec ports provide SAN connectivity to HDS storage and Enterprise-class tape Reliability/Availability Brocade is the market leader in FC switch technology Multiple switches provide redundancy for SAN components
- 15. SAN Storage – Backup/Recovery Veritas Net Backup Lan-free, server-free backup, directly from SAN storage through the switch to Enterprise-class StorageTek Automated Tape Library Performance Backup data moves at fibre channel speed, up to 100 times faster than LAN backup, 5 times faster than SCSI
