• 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.

Storage
Storage Area Network
ESCON Director

• Simplified cabling
• Improved performance
• Increased distance
• Non-disruptive upgrades

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

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

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

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

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.
