Storage performance is an important factor of storage design. The storage must be designed to meet not only the capacity requirements but also the performance requirements for writes and reads to disk. Disk performance is measured in Input/Output per Second (IOPS). One disk read request or one disk write request is equal to one IO. The storage performance must support the current requirements and growth.
Determining storage performance requirements
How to do it...
The IOPS required to support an application is calculated based on the percentage of read IO, the percentage of write IO, and the write penalty of the RAID level the workload will be hosted on.
To calculate the IOPS requirements, perform the following steps:
- Determine...
