EMC D-XTR-MN-A-24 - Dell XtremIO Maintenance Achievement

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.

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.

In Dell XtremIO X2 arrays, the Disk Protection Groups (DPGs) are organized in such a way that each DPG spans multiple rows of drives. Specifically, DPG-2 in an XtremIO-X2 DAE (Disk Array Enclosure) uses the drives in Row 1 and Row 2. This configuration is designed toensure redundancy and fault tolerance. The drives in these rows collectively form the DPG, which is responsible for data protection and performance optimization.

XtremIO X2 clusters are designed for efficient space utilization in data center racks.

A four X-Brick XtremIO X2 cluster requires specific rack space allocation.

Each X-Brick occupies 5U of rack space. Therefore, four X-Bricks would require 20U.

Additionally, the physical XtremIO Management Server (XMS) occupies 1U of rack space.

In total, the four X-Brick XtremIO X2 cluster with a physical XMS requires 21U of rack space.

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.

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.
