Objectives
  • Business Drivers
  • SAN Definition
  • SAN Potential
  • Not just SCSI storage!
  • Real World Experiences
  • Tangible ROI
  • Ideal SAN Applications
  • A Look Ahead
  • Conclusion

3
Business Challenges
  • Explosion of data and network traffic
  • Increasing value of Information
  • Non-stop information access
  • Quality of service and Service Level Agreements
  • Pace of technology change and obsolescence
  • Shortage of skilled personnel
  • Increasing need for agility - Internet Time

4
Storage Spending is Increasing
Worldwide Disk Storage Systems Spending
  • 3B spending increase from 98 to 99
  • 11.5 spending increase through 2003
  • Growth coming from applications outside of
    typical data center control

Spending (M)
5
TBs are Growing Faster than Staffing
  • Storage capacity is increasing 80 p.a.
  • Storage managers must improve efficiency more
    than 60 p.a.

SAN Drivers
  • Customer requirements
  • Backup / Disaster Recovery
  • Storage Management
  • Storage Server Consolidation
  • Scalability (Performance Capacity)
  • Continuous Availability
  • Data Replication / Data Movement / Data Sharing
  • Ease of Operation
  • Growth Enablement
  • Clustering Enablement
  • Server to Server Communications

8
SANs are a reality
Storage
Storage Area Network
ESCON Director
  • Simplified cabling
  • Improved performance
  • Increased distance
  • Non-disruptive upgrades
  • Logical management
  • Clustering and fail-over support
  • Data replication over distance
  • Data movement

9
Fibre Channel, An Enabling Technology
A high-speed SERIAL interface -200MB/s Supports
existing applications Combines advantages of
channels and networks Utilizes optical fibre for
distance and noise immunity Enables scalable
server/storage area networks
10
HDS SAN Definition
  • A SAN is a infrastructure of storage and server
    resources,
  • Attached via Fibre Channel Protocols,
  • Which enable any to any connectivity between
  • servers and storage
  • storage to storage
  • and server to server

11
Benefits of a SAN
  • Independently scalable storage and servers
  • reduces cost
  • increases scalability
  • Fibre Channel vs. SCSI superiority
  • Higher bandwidth - 100MB/s HD Fibre
  • Greater distances - 10Km vs 30m
  • FC protocol more efficient than TCP/IP
  • Removes Server/Storage traffic from LAN
  • Applications on LAN run faster
  • Backups performed faster
  • Network Attached Storage has the opposite effect
  • Increases storage resource manageability

12
Today Server Attached Storage
Islands of Computing

SAN Specialised Network Attached Storage
14
Ideal Applications for SAN
  • Applications which require large data transfers
  • Backup and restore
  • Data copy and replication
  • Server and Storage Consolidation
  • Applications which require shared access to data
  • High availability and load balancing clusters
  • Parallel data base clusters
  • Enterprise Application Integration
  • High availability, high growth applications
  • Messaging, e-Commerce, ERP

15

Control
LAN
  • Control is communicated over the LAN
  • Data is moved through the SAN by the Client
  • Removes large block data traffic from the LAN
  • Available with ARCserve, Harbor, Legato, Veritas

16
A SAN Implementation Strategy
  • Install shadow backup SAN
  • Low risk application for installation of a new
    infrastructure
  • High payback with reduction of backup window
  • Gain user confidence in SAN technology
  • Extend SAN into other application areas during
    transition windows
  • Installation or extension of data base
  • Installation or consolidation of servers
  • Invest in storage resources that are Fibre Fabric
    enabled and support open interoperability

17

Freedom Data Network Roadmap
Single Image Data Network - Heterogeneous hosts
and shared storage present single image view to
the application. Policy based load balancing and
recovery. Provides availability, scalability, and
Quality of service.
Shared Data Network - Heterogeneous hosts have
access to shared file system. On the fly
configuration of server and storage nodes.
Continuous operation. Live file expansion. VIA
messaging over SAN
Share Nothing Data Network - Heterogeneous hosts
see assigned LUNs centrally managed. Online LUN
Configuration. VIA data transfers between hosts.
Network enabled Storage - Heterogeneous hosts
have Trusted access to storage pool, Manually
enforced through various LUN masking and zoning
implementations.
