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

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

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.

Answer : B

XtremIO upgrade packages can be found on the support.emc.com website. This is the official support site for Dell EMC products, where customers can download software updates, including XtremIO upgrade packages. The site provides access to various resources, including documentation, knowledge articles, and software downloads for Dell EMC products12.

To find and download XtremIO upgrade packages, follow these steps:

Go to support.emc.com.

Log in with your Dell EMC support account credentials.

Navigate to the 'Downloads' section.

Search for XtremIO in the product list.

Select your specific XtremIO model and version.

Locate the upgrade package you need and download it.

It's important to ensure that you have a valid support contract and the necessary permissions to access and download software updates from support.emc.com1.

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

Answer : A

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.

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

Answer : A

In an XtremIO X1 cluster, it is required that all SSDs (Solid State Drives) be configured with identical drive sizes. This uniformity ensures optimal performance and balanced wear leveling across the drives, which is crucial for maintaining the efficiency and reliability of the storage system.

Answer : A

For an XtremIO X2-S, the ports used on the InfiniBand switches for an Inter-Switch Link (ISL) connection are typically high-numbered ports, which are usually at the end of the port range on the switch. While the specific port numbers can vary depending on the switch model and configuration, ports 35 and 36 are commonly used for ISL connections in many configurations1.

The process to identify the ISL ports is as follows:

Access the InfiniBand switch via the management interface.

Use the appropriate command to list the port configuration (this command can vary based on the switch's firmware).

Identify the ports configured for ISL, which will be indicated in the port configuration settings.

It's important to refer to the official Dell XtremIO Maintenance Achievement document or the InfiniBand switch documentation for the exact port numbers as they can differ based on the switch model and the cluster configuration1.

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.
