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.
