iops measurements
IOPS Measurements
  • Rotational Speed
    • Seek and Latency
  • Linear and Spatial density
  • RAID Protection
  • Read/Write ratio
  • Cache Hits
theoretical calculation
Theoretical Calculation
  • Theoretical IOPS of a Spindle
    • IOPS = 1000/(Average Seek + Latency)
    • Average Seek = (Ws + Rs)/2
    • Latency (ms) = (1000/RPS)/2
      • Computes to 2.99ms for 10,025 RPM Drives
      • Computes to 2.00ms for 15,00 RPM Drives
    • Ex: 1000/(5.7ms + 2.99) = 115 IOPS
practical calculation
Practical Calculation
  • Accounting for R/W Ratio & Read Hits

IOPS = 1000/[(Rs+L)*Rm*Read% + (Ws+L)*Write%]

Taking into account the # of Spindles/Raid Group, the

Raid Penalty and type of workload, one can easily

Calculate the #of Spindles required to process a given

Number of IOPS for a given workload type.

Growth Trends

Demand for bandwidth is growing faster than capacity requirements

switch architecture 2000

“(…) the most innovative technology), which built a SAN rather than a backbone bus into its Storage Sub-Systems to deliver exceptional performance and capacity flexibility.”

“The company’s new Switch Architecture further demonstrated their commitment to technological innovation and business-enabling solutions, and redefines the industry standard, once again.”

tangible benefits
Tangible Benefits
  • Reduced Total Cost of Ownership
    • Enables Massive Consolidation & Centralization
      • Reduced complexity by simplifying storage networking environments with fewer switches, connections
    • Simplified management
      • Simplified and automated tools reduces time spend managing storage: people can be re-deployed for other tasks.
    • Reduced software licensing and maintenance
      • Through improved capacity utilization: less capacity then lower licensing and maintenance
        • One 6TB versus three 4TB
        • $700K plus
    • Improved Environmental Costs
      • Reduced floor space, power, cooling
network management requires open standards based approach

Network Management Requires Open Standards-Based Approach
  • Exchanging APIs leads to a growing web of proprietary interfaces
  • Storage networks require an object-based Common Information Model (CIM), for management of mixed environments
  • Web-Based Enterprise Management(WBEM), provides a standard managementinterface for existing Web servers
  • CIM/WBEM is an industry accepted specification that provides a truly open and adaptive standard for heterogeneous storage management
  • Software vendors write to an open interface
    • No need for proprietary commitments
  • Hardware vendors provide a common object- based management interface that still enables them to provide differentiation

The Importance of a Message Bus

ISVn

CIM/WBEM

  • A CIM object enables ISVs to codeto a common interface
  • However, ISVs still need to communicate with each otherto reduce management complexity
  • A Simple Object Access Protocol (SOAP) message bus provides a standard interface for communication between ISV products
  • New Application Framework should be based on a CIM/SOAP management message bus.
