EMC Updated D-XTR-MN-A-24 Exam Questions and Answers by ella-mae

The SAS (Serial Attached SCSI) connection speed for an XtremIO X1 is 6 Gb/s, while for an XtremIO X2, it is 12 Gb/s. The increased speed in the X2 model enhances data transfer rates and overall performance, reflecting advancements in the hardware capabilities of the newer generation.

The highlighted port in the exhibit is a Fibre Channel (FC) port. This port type is used for high-speed data transfer between the storage controller and connected devices or networks. Fibre Channel is a technology known for its reliability and speed, making it suitable for storage area networks (SANs).The identification of the FC port is based on recognizing the physical characteristics of FC ports, such as their shape and typical placement on storage devices, as well as knowledge about Dell’s XtremIO systems’ configuration options1.

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

The minimum XtremIO software version required for expanding a Starter X-Brick cluster is 4.0.4. This version includes the necessary features and improvements to support the expansion process, ensuring compatibility and optimal performance.

In an XtremIO X1 cluster, the system is designed to tolerate the failure of one DAE Controller SAS port without any impact on the service or data integrity. This is because the architecture of the XtremIO X1 includes redundancy and failover mechanisms that ensure continuous operation even when individual components fail.The failure of a single SAS port would trigger these mechanisms, allowing the system to maintain normal operations and prevent data loss, service degradation, or loss of service1.
