Question 25/30

Which I/O elevator setting should be selected for use with XtremIO?

A. noop

B. anticipatory

C. deadline

D. cfq

Correct Answer: A

The I/O elevator setting for use with XtremIO should be selected based on the operating system and the workload characteristics. For systems running Red Hat Enterprise Linux (RHEL) and connecting to XtremIO X2 storage arrays, the recommended I/O elevator settings are either noop or deadline.The noop scheduler is often recommended for SSDs and all-flash arrays like XtremIO because it is a simple FIFO queue that does not do any merging or reordering of I/O requests, which is unnecessary for SSDs due to their low latency and high performance1.
