Storage Area Network(SAN)
SAN Definition
SAN componentsFibre Channel NetworkHost 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 . . . .
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
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
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
User Requirements
Increased storage capacity Support for multiple storage/server architecturesContinuous/High availabilityCross-platform solutions
Why SAN ?
Why SAN ?
User Requirements
Support higher levels of I/O activityHigher performance backup/restoreData sharingSecure Assets
SAN Benefits
Performance FC @ 200MB/sec vs SCSI @ 40MB/sec
AvailabilityRedundancy, non-disruptive upgrades
Scalability
Add or re-deploy storage as needed
SAN Benefits
FlexibilityNew, advanced SAN devices can easily be added as older devices wear out or become obsolete
Backup/restore/archiveMove data at FC speed vs LAN (up to 100x)
Centralized storage managementManage SAN as a single entity (shared resources)
SAN Benefits
Reduced costsStorage management, capacity overhead
Data sharing
Access to any data on SAN
Secure Assets
Multiple layers of security to ensure data integrity
SAN Benefits
Remote ReplicationGeographical data replication for disaster recovery
SAN to SAN Copy
Copy data from disk to disk geographically using SAN technology

SAN Storage –Performance Connectivity
Hundreds of 2-Gbit/sec Fibre Channel interfaces allow thousands of MB/sec aggregate data rates
Reliability/AvailabilityFully redundant components allow for non-disruptive maintenance and upgrades
Scalability 28 TB disk storage now installed and growing28 GB cache, can scale to 32 GB cache memory

The Network – Brocade Switches
Performance/ConnectivityHundreds of 2-Gbit/sec ports provide SAN connectivity to HDS storage and Enterprise-class tape
Reliability/AvailabilityBrocade is the market leader in FC switch technologyMultiple switches provide redundancy for SAN components
SAN Storage – Backup/Recovery
Veritas Net BackupLan-free, server-free backup, directly from SAN storage through the switch to Enterprise-class StorageTek Automated Tape Library
PerformanceBackup data moves at fibre channel speed, up to 100 times faster than LAN backup, 5 times faster than SCSI
