How to reduce response time in a SAN

When it comes to storage area network (SAN) metrics and measurements, such as bandwith, input/output per second (IOPS) and utilization, more is usually better. However, when it comes to response time and latency (the amount of time it takes to complete a task), less is more.

What you will learn: This podcast offers information about how to improve I/O performance and lower response time in a SAN.

When it comes to storage area network (SAN) metrics and measurements, such as bandwith, input/output per second (IOPS) and utilization, more is usually better. However, when it comes to response time and latency -- or the amount of time that it takes to complete a task -- less is definitely more.

In this podcast, Greg Schulz looks at the components of a SAN that can have an impact on response time and suggests ways to boost performance in those areas. The recording covers:

  • Application, server, driver and adapter issues
  • Network switches, routers, bridges, interswitch links, trunks and cabling
  • Storage system configuration and components
  • Download "How to reduce response time in a SAN."
