The correct sequence of steps to install a virtual XMS prior to creating the cluster on an XtremIO X2 is:

Deploy the OVF Template

Configure the XMS

Transfer the Installation Package to the XMS Server

Install only the XMS

Display the Installation Package on the Storage Controller

Deploy the OVF Template: Begin by deploying the Open Virtualization Format (OVF) template which is a pre-configured virtual machine that contains all necessary installation files.

Configure the XMS: After deployment, configure XtremIO Management Server (XMS) which involves setting up network configurations and other system settings.

Transfer the Installation Package to the XMS Server: The next step is transferring all necessary installation files for XtremIO to your newly configured XMS server.

Install only the XMS: Proceed with installing only XtremIO Management Server software on your server.

Display the Installation Package on Storage Controller: Finally, ensure that your storage controller can access and display all relevant installation packages for further processes.

These steps are outlined in the Dell XtremIO Maintenance Achievement document and provide a systematic approach to installing a virtual XMS, which is essential for managing and creating an XtremIO X2 cluster.

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.

This performance metric is derived from the system’s ability to deliver linear scalability, meaning that two X-Bricks can deliver twice the IOPS of a single X-Brick configuration2.

The calculation for this is based on the performance of a single X-Brick, which can achieve up to 300,000 IOPS under the same workload conditions.Therefore, with two X-Bricks, the system can achieve double that amount, resulting in 600,000 IOPS1.

This information is crucial for planning and sizing purposes, ensuring that the storage array meets the performance requirements of the applications it supports2.

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

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.

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.

The correct sequence of steps to power up an XtremIO X1 cluster after an emergency shutdown is as follows:

Determine the cause of the shutdown

Power up the Battery Backup Units

Power up the XMS

Power up the Storage Controllers

Start the cluster

Detailed Explanation with References:

Determine the cause of the shutdown: Before powering up the system, it is essential to understand why the emergency shutdown occurred to prevent reoccurrence.

Power up the Battery Backup Units: The BBUs provide the necessary power to the storage controllers during power-up.

Power up the XMS: The XtremIO Management Server must be powered up to manage and monitor the storage system.

Power up the Storage Controllers: Once the BBUs and XMS are operational, power up the storage controllers.

Start the cluster: Finally, start the cluster to bring the XtremIO system back online and resume normal operations.
