D-XTR-MN-A-24 Exam Dumps : Dell XtremIO Maintenance Achievement

This performance metric is derived from the system’s ability to deliver linear scalability, meaning that two X-Bricks can deliver twice the IOPS of a single X-Brick configuration2.

The calculation for this is based on the performance of a single X-Brick, which can achieve up to 300,000 IOPS under the same workload conditions.Therefore, with two X-Bricks, the system can achieve double that amount, resulting in 600,000 IOPS1.

This information is crucial for planning and sizing purposes, ensuring that the storage array meets the performance requirements of the applications it supports2.

=========================

To successfully operate Technician Advisor on an XtremIO X2, TCP ports 80 and 443 need to be open between the XMS (XtremIO Management Server) and X1-SC1 (Storage Controller). These ports are used for HTTP and HTTPS communication, respectively, allowing for secure management and operation of the storage system.

The correct sequence of steps to power up an XtremIO X1 cluster after an emergency shutdown is as follows:

Determine the cause of the shutdown

Power up the Battery Backup Units

Power up the XMS

Power up the Storage Controllers

Start the cluster

Detailed Explanation with References:

Determine the cause of the shutdown: Before powering up the system, it is essential to understand why the emergency shutdown occurred to prevent reoccurrence.

Power up the Battery Backup Units: The BBUs provide the necessary power to the storage controllers during power-up.

Power up the XMS: The XtremIO Management Server must be powered up to manage and monitor the storage system.

Power up the Storage Controllers: Once the BBUs and XMS are operational, power up the storage controllers.

Start the cluster: Finally, start the cluster to bring the XtremIO system back online and resume normal operations.
