DELL EMC Updated D-XTR-MN-A-24 Exam Questions and Answers by everley

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.

The Eaton 1550 Evolution BBU (Battery Backup Unit) uses 1 DB9 and 1 RJ50 connector. These connectors are used for communication and management purposes, ensuring that the BBU can interface correctly with other components of the system.

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.

In preparation for a single-to-dual online cluster expansion, the power cables that are pre-staged by being connected to Power Distribution Unit B (PDU-B) only are for the right-side Power Supply Units (PSUs) of the Storage Controllers (SCs). Specifically, these would be the power cables for X2-SC1-PSU-R and X2-SC2-PSU-R.This configuration ensures that there is a balanced power distribution across the PDUs and that the new cluster components will have power connectivity once they are physically installed1.

The process typically involves:

Identifying the correct power cables for the SCs’ PSUs.

Connecting these cables to the designated ports on PDU-B.

Ensuring that the cables are properly managed and labeled for easy identification during the expansion process.

This procedure is part of the standard practices for expanding an XtremIO cluster, as detailed in the Official Dell XtremIO Maintenance Achievement document1.
