Dell EMC Dell XtremIO Maintenance Achievement D-XTR-MN-A-24 Exam Questions

Answer : B

To replace a power supply unit (PSU) in a storage controller of an XtremIO cluster, a specific command needs to be executed.

The correct command to initiate this process is replace-storage-controller-psu sc-psu-id=1 cluster-id='ABC123'.

This command specifies the action to replace the PSU (replace-storage-controller-psu), the PSU ID (sc-psu-id=1), and the specific cluster ID (cluster-id='ABC123').

Using this command ensures that the correct PSU in the specified cluster is prepared for replacement.

Answer : D

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.

Answer : C

The show-storage-controllers command is used in XMCLI to verify the IP addresses of the Storage Controllers after they have been changed. This command provides detailed information about the status and configuration of the storage controllers, including their IP addresses.

Answer : A

In a multi X-Brick XtremIO X1 cluster, the failure of more than half of the COM (communication) cables forces the cluster into a degraded mode. This degraded mode is a protective measure to ensure that the cluster can continue operating with reduced performance and redundancy until the issues with the COM cables are resolved.

Answer : C

The Technician Advisor can be found on SolVe Desktop. SolVe Desktop is a comprehensive tool provided by Dell EMC that includes installation, maintenance, and troubleshooting procedures for various Dell EMC products, including XtremIO. It is an essential resource for technicians working with these systems.

Answer : B

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.

Answer : A

In a multi-brick XtremIO X2-R array, a 36 port InfiniBand switch is used. This type of switch provides the necessary number of ports to accommodate the connectivity requirements of a multi-brick configuration, ensuring high-speed data transfer and communication between the bricks and other components of the storage array1.

The InfiniBand switch plays a crucial role in the XtremIO X2-R's architecture, as it allows for the interconnection of multiple bricks, which collectively contribute to the array's performance and scalability. The 36 port switch ensures that there are enough ports available for current use and potential future expansion1.
