Question 1
What must be submitted with an RPQ prior to a dispersed XtremlO cluster installation?
Explanation:
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.
Question 2
Which ports need to be open between the XMS and X1-SC1 to successfully operate Technician Advisor on an XtremIO X2?
Explanation:
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.
Question 3
Into which directory must the XtremApp software be copied on the XMS?
Explanation:
The XtremApp software must be copied into the /xtremapp directory on the XtremIO Management Server (XMS). This directory is specifically designated for the XtremApp software, ensuring that it is stored in the correct location for installation and execution1.
The process for copying the software typically involves:
Accessing the XMS via a secure shell (SSH) connection.
Navigating to the root directory.
Locating or creating the /xtremapp directory.
Using the appropriate command to copy the XtremApp software from its source location to the /xtremapp directory on the XMS.
It is important to follow the Official Dell XtremIO Maintenance Achievement document for the correct procedures and to ensure that the software is placed in the proper directory for successful installation and operation1.

Question 4
Where can the XtremlO power requirements be found?
Explanation:
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.
Question 5
Which document should be referenced when modifying the IP addresses on an XtremIO X2 cluster that will remain in the same IP network?
Explanation:
When modifying the IP addresses on an XtremIO X2 cluster that will remain in the same IP network, the appropriate document to reference is the 'XtremIO Storage Array User Guide.' This guide contains detailed instructions and best practices for changing network configurations, including IP address modifications.
Question 6
Which type of InfiniBand switch is used in a multi-brick XtremIO X2-R array?
Explanation:
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.
Question 7
Why is an extra rack unit space used between X-Bricks when installing a multi X-Brick XtremIO X2?
Explanation:
An extra rack unit space is used between X-Bricks when installing a multi X-Brick XtremIO X2 to accommodate the cable management duct. This space is essential for organizing and managing the cables, ensuring proper airflow, and making maintenance tasks easier.
Question 8
DRAG DROP
From bottom to top, what is the correct racking order of the first four components to expand an XtremlO X1 configuration from a dual X-Brick to a quad X-Brick?
Explanation:
X3-SC1
X3-DAE
X3-BBU
X3-SC2
Question 9
In an XtremIO X2, what is the maximum number of lifetime cycles for NVRAM?
Explanation:
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.
Question 10
When comparing XtremlO X1 to XtremlO X2, how much memory is installed in a Storage Controller that has a DAE attached with 400 GB SSDs?
Explanation:
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.
