Free EMC D-XTR-MN-A-24 Practice Exam with Questions & Answers

Verify no host I/O: Ensure that there are no active I/O operations from the hosts connected to the XtremIO array. This is crucial to avoid data loss or corruption.

Verify the cluster PSNT and health: Check the Primary Serial Number Tag (PSNT) and the health status of the cluster to ensure everything is functioning properly before proceeding with the shutdown.

Disable notifications: Temporarily disable any notifications to avoid unnecessary alerts during the shutdown process.

Stop the cluster service: Gracefully stop the cluster service to ensure that all processes and services are properly terminated.

Power off the hardware: Finally, power off the hardware to complete the planned shutdown of the XtremIO X2.

To service an XtremIO X2 with the Technician Advisor tool, the connection is made through the dedicated Management port located on the back of the Storage Controller (SC).This port is specifically designed for management tasks and allows service technicians to access the system for diagnostics and configuration using the Technician Advisor tool1.

The process typically involves:

Locating the dedicated Management port on the back of the SC.

Connecting a compatible cable from the technician’s device to the Management port.

Using the Technician Advisor tool to perform the necessary service tasks.

This information is outlined in the Official Dell XtremIO Maintenance Achievement document, which provides detailed instructions for servicing and maintaining XtremIO X2 storage systems1.

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

In an XtremIO X1 cluster, the system is designed to tolerate the failure of one DAE Controller SAS port without any impact on the service or data integrity. This is because the architecture of the XtremIO X1 includes redundancy and failover mechanisms that ensure continuous operation even when individual components fail.The failure of a single SAS port would trigger these mechanisms, allowing the system to maintain normal operations and prevent data loss, service degradation, or loss of service1.

The XtremIO X2 storage system can be expanded for capacity (Scale-Up) or both capacity and performance (Scale-Out). The system begins with a single building block, called an X-Brick, with a minimum of 18 SSDs.When additional capacity is required, the system scales up, with up to 72 SSDs for a single X-Brick1. Therefore, to upgrade a single X-Brick XtremIO X2 cluster that already contains 36 SSDs, the minimum number of SSDs required would be 18, which is the base configuration for an X-Brick.

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

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.

The virtual XtremIO Management Server (XMS) OVA file can be found in theTools & Utilitiesdownload section on support.emc.com.This is confirmed by the information provided in the Dell XtremIO Maintenance Achievement document, which details the resources and procedures for maintaining XtremIO products, including the deployment of the XMS1.

In an XtremIO X2 system, the maximum number of lifetime cycles for NVRAM is 10,000. This number represents the total count of write and erase cycles the NVRAM can endure throughout its lifespan, ensuring data integrity and reliability over time.

The XtremIO Storage Array Site Preparation Guide contains the power requirements for the XtremIO system. This guide includes detailed specifications for power consumption, electrical requirements, and other environmental factors necessary for proper installation and operation.

When comparing XtremIO X1 to XtremIO X2, the amount of memory installed in a Storage Controller with a DAE attached with 400 GB SSDs differs. For the X1, it is 256 GB, while for the X2, it is 512 GB. This increase in memory in the X2 model supports higher performance and improved handling of data operations.

Based on the provided exhibit, ports "b" and "d" are used for FC2 (Fibre Channel 2) and iSCSI1 connections on an XtremIO X1. These ports are designated for specific connection types to ensure optimal performance and correct configuration of the storage network.
