When entering a generic workload into the XtremIO Sizing Tool, the required values are IOPs, I/O

size, and bandwidth. These parameters are essential for accurately sizing the storage system to

ensure it can handle the expected workload. IOPs (Input/Output Operations Per Second) measure

the number of read/write operations the storage system can perform in a second. I/O size refers to

the size of each read/write operation, and bandwidth is the total amount of data that can be

transferred in a given time frame.

Reference:

The XtremIO Performance Documents discuss different workload testing parameters, including I/O

size and limits, which are relevant to sizing the array1.

The Dell XtremIO Design Achievement document outlines the critical components and best practices

for designing solutions with XtremIO and X2 storage systems, which would include considerations for

workload sizing2.
