## Slide 1

## Storage Area Network(SAN)

## 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 . . . .***

## 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 architectures
- Continuous/High availability
- Cross-platform solutions

*Why SAN ?*

## User Requirements

*User Requirements*

- Support higher levels of I/O activity
- Higher performance backup/restore
- Data sharing
- Secure Assets

## SAN Benefits

- Performance
- FC @ 200MB/sec vs SCSI @ 40MB/sec
- Availability
- Redundancy, non-disruptive upgrades
- Scalability
- Add or re-deploy storage as needed

## 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)

## SAN Benefits

*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

## SAN Benefits

*SAN Benefits*

- Remote Replication
- Geographical data replication for disaster recovery
- SAN to SAN Copy
- Copy data from disk to disk geographically using SAN technology

## SAN Servers – Operating Systems

## 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
- 105 TB disk storage now installed and growing
- 28 GB cache, can scale to 32 GB cache memory

***9960 Storage***

## 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

## 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

## SAN Replication – Disaster Recovery

## SAN Replication – Disaster Recovery

*SAN Replication – Disaster Recovery*

- ...are linked together via the USDA Wide Area Network.

- The link is an asynchronous channel extension for distance and secured with encryption.

## NITC Offering

- NITC is offering SAN as a total **Enterprise** solution for your immediate and long term IT needs.
