Doing capacity management for storage can be difficult with the many complex
and varied technologies being used.
Given all of the options available for data storage strategy, a clear understanding of the architecture is important in identifying performance and capacity concerns. A technician looking at metrics on a server is often seeing only the tip of a storage iceberg. However, the host view is important when looking at measured I/O response.
If response times are severely impacted on a busy server, then end users of the hosted applications will also be impacted. High response at the OS typically originates somewhere in the backend storage infrastructure.
Tracking and reporting on key metrics at the host and backend storage controllers can prevent these incidents from occurring and having the right tools in place can be the difference between prevention and firefighting.
I'll be taking a closer look at key metrics for storage performance at my webinar on Wednesday covering:
Storage architecture
Virtualization
Key metrics for the host and backend storage environment
Reporting on what is most important
