Resilient Storage Networks: Designing Flexible Scalable Data Infrastructures

What This Chapter Will Do For You
This chapter looks at performance and capacity topics pertaining to storage networking. Adequate performance and capacity are essential to a resilient storage network, regardless of the size of the business it is supporting. Some of the items you will learn about in this chapter include:
How lack of performance and capacity can negatively impact business revenues
Understand the relationship between availability, performance, and capacity
How to manage storage and storage networking resources and performance
Cost impact of simply adding more hardware and the hidden management cost
How to more effectively acquire technology by knowing what you need and when to add more
What do you mean we need more, what happened to what I just bought? Have you encountered the feeling regarding storage that you need more, yet you just bought more and wonder where it went? This chapter looks at performance and capacity planning for storage networks, building on the material covered in previous chapters. This chapter leverages design items covered in Chapter 8 (storage networking design) in particular, assessment of resources. Performance and capacity planning are associated with storage networking design and storage resource management. Performance and capacity planning are important for resilient storage networks to ensure adequate performance under different workloads and available resources when needed.
For those who are familiar with performance engineering, tuning, Storage Resource Management (SRM), capacity planning, hardware planning, and configuration, much of this will be review...
