EMC Proven Professional – XtremIO Solutions Expert — Question 14

To determine Service Level Objective compliance on a VMAX3, where is the I/O response time measured?

Answer options

• A. Frontend Directors
• B. Host Bus Adapters
• C. SAN Switches
• D. Backend Directors

Correct answer: B

Explanation

The I/O response time is measured at the Host Bus Adapters because they are responsible for interfacing between the storage system and the host servers. The other options, such as Frontend Directors and Backend Directors, manage data traffic but do not directly measure I/O response times for compliance assessments.
