SAN Infrastructure Technology Overview
Benefits of SAN-Based Storage
  • Increased storage asset utilization
  • Broader host server connectivity
  • Centralized storage management
  • Better TCO

10-Gigabit Ethernet Expands iSCSI Breadth of
Deployment
November 2007 Gartner Data Center Conference
Polling Survey Results
  • What is the likelihood that you will install an
    iSCSI SAN in the next 12 months?
  • 28 Very likely
  • 20 Likely
  • 52 Not likely
  • 19 said that 10Gbps Ethernet will affect their
    storage infrastructure over the next three years
  • What is the likelihood that you will replace your
    Fibre Channel SAN with 10Gbps Ethernet?
  • 7 Very likely
  • 19 Likely
  • 74 Not likely

5
Boot From SAN Reducing Storage Requirements,
Improving Change Control
High-Availability Disk Array
15K rpm HDDs
  • Rapid Server Recovery
  • Rapid Server Deployment
  • Streamline Administration
  • Reduced Acquisition Costs
  • Reduced Power Consumption
  • Reduced Cooling Consumption
  • Improved Reliability/Availability

10K rpm HDDs
7.2K rpm HDDs

Thin Provisioning Automating Storage Capacity
Management, Improving Utilization

Quality of Storage Service via Automated Tiered
Disk Storage
  • Reduced storage
  • hardware costs
  • High-performance
  • Low-capacity disk drives
  • Less power, heat
  • and space
  • Medium-performance
  • Medium-capacity
  • disk drives
  • Server and application
  • agnostic
  • Low-performance
  • High-capacity
  • disk drives
  • Optimized price/
  • performance
  • Simplifies
  • management

8
Recommendations
  • Automate storage management to gain agility and
    flexibility
  • Implement an iSCSI-based SAN on a dedicated
    Ethernet infrastructure
  • In an FC SAN environment, standardize
    infrastructure components to reduce
    interoperability issues
  • Buy an integrated and tested solution from an
    experienced source
  • Don't try to do it all at once!
