What should be done prior to presenting XtremlO volumes to a new Linux host?

ADisable the DM-MPIO

BDisable the I/O elevators

CSet the least queue depth

DRebuild GRUB

Show Suggested Answer

Suggested Answer: B

Before presenting XtremIO volumes to a new Linux host, it is recommended to disable the I/O elevators. This step is crucial for optimizing performance and ensuring that the storage system works efficiently with the host's operating system.

The I/O elevator is a Linux kernel feature that controls the order in which I/O operations are submitted to storage devices. It's designed to optimize the way the Linux kernel handles write and read requests. However, in the context of high-performance storage systems like XtremIO, the default I/O scheduling might not be optimal. Disabling the I/O elevators allows the XtremIO storage system to manage the I/O requests more efficiently, leveraging its built-in capabilities for performance optimization.

This information is corroborated by the Official Dell XtremIO Deploy Achievement document, which outlines the best practices for configuring XtremIO systems in various environments, including Linux hosts1.
