EMC Storage Administrator D-XTR-MN-A-24 New Questions

When submitting a Request for Product Qualification (RPQ) prior to a dispersed XtremIO cluster installation, it is necessary to include a wiring diagram and an X-Brick component location diagram. The wiring diagram provides a detailed representation of the electrical connections between the components, while the X-Brick component location diagram shows the physical placement of the X-Brick components within the installation environment.These documents are essential for planning the installation to ensure that all components are correctly positioned and connected for optimal performance and serviceability1.

The process for preparing these documents typically involves:

Creating a detailed wiring diagram that outlines all the necessary connections between the X-Brick components and other infrastructure elements.

Developing an X-Brick component location diagram that illustrates where each component will be physically located in the data center.

Reviewing the diagrams to ensure they meet the technical requirements and specifications for a dispersed XtremIO cluster installation.

Submitting the diagrams along with the RPQ for approval before proceeding with the installation.

These steps are crucial for a successful installation and are outlined in the Official Dell XtremIO Maintenance Achievement document1.

To expand a Starter X-Brick cluster (which typically begins with one X-Brick) to an eight X-Brick cluster, a total of three expansions are required. Each expansion step in XtremIO can typically double the number of X-Bricks, thus:

First expansion: From 1 X-Brick to 2 X-Bricks.

Second expansion: From 2 X-Bricks to 4 X-Bricks.

Third expansion: From 4 X-Bricks to 8 X-Bricks.

This sequence ensures that the storage array scales properly, maintaining performance and redundancy.

In a multi X-brick cluster, each X-brick consists of multiple Disk Array Enclosures (DAEs) that work together to provide storage and data redundancy.

If both DAE controllers in a single X-Brick fail, the impact is localized to the LUNs (Logical Unit Numbers) that store data on that particular DAE.

The entire cluster does not shut down; rather, only the data on the affected DAE becomes unavailable.

This design ensures that the rest of the cluster continues to operate normally, albeit with potential performance degradation depending on the data distribution and workload.

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.
