Capacity Planning and Performance Management
of Storage Area Networks (SANs)

Capacitas Training Centre,
London, United Kingdom.
3 Days

Learn how to:

  • Collect capacity and performance data across the different components of the SAN infrastructure
  • Build capacity models of your SAN infrastructure to make informed and cost effective decisions on capacity upgrades
  • Optimise your SAN performance for different workload types
  • Build performance models of your SAN infrastructure in order to predict the performance of applications that use storage technology.

Course Brief

Most modern enterprises are migrating to Storage Area Network (SAN) architectures for a variety of reason, including cost, security and business continuity. However, the migration to SAN is not an easy path. SANs bring a wealth of performance and capacity implications, depending on the architecture and technology chosen. This course is designed to give the Storage Capacity Analyst an understanding of how to cope with the issues surrounding SANs.

Course Prerequisites

Course Audience

  • Capacity Planners
  • Performance Analysts
  • Performance Modellers
  • SAN Managers
  • ICT Managers
  • Data Centre Managers
  • Technical Architects
  • System Architects

How Your Organisation Will Benefit

  • Staff gain a better understanding of the complex SAN technologies and aspects of this technology that impact capacity and performance
  • Reduction in unnecessary capacity upgrades and hence reduction in capital expense
  • Reduction in the number of performance related incidents and therefore potential service penalties
