In the event of a power failure, the XtremIO X2 array is designed to protect the journal data using a combination ofSupercapacitorandNVRAM. The NVRAM (Non-Volatile Random Access Memory) ensures that the data remains intact without power, while the supercapacitor provides the necessary energy to maintain the power to the NVRAM during the outage.This design allows the XtremIO X2 array to preserve the integrity of the journal data until normal power can be restored1.

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

The XtremIO X2 storage system can be expanded for capacity (Scale-Up) or both capacity and performance (Scale-Out). The system begins with a single building block, called an X-Brick, with a minimum of 18 SSDs.When additional capacity is required, the system scales up, with up to 72 SSDs for a single X-Brick1. Therefore, to upgrade a single X-Brick XtremIO X2 cluster that already contains 36 SSDs, the minimum number of SSDs required would be 18, which is the base configuration for an X-Brick.

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

When creating a cluster, in addition to the cluster name, the following parameters are required: the expected number of X-Bricks, the IP address of X1-SC1 (the first Storage Controller), and the package name. These parameters are essential for setting up the cluster configuration and ensuring proper communication between components.

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.

Questions no:Which document contains the detailed steps for re-imaging the Storage Controller when preparing for a single-to-dual X-Brick expansion?

Verified Answer:C.XtremIO Hardware Installation and Upgrade Guide

Step by Step Comprehensive Detailed Explanation with References:The detailed steps for re-imaging the Storage Controller when preparing for a single-to-dual X-Brick expansion are contained in theXtremIO Hardware Installation and Upgrade Guide.This document provides comprehensive instructions on the physical installation, initial configuration, and upgrade procedures for XtremIO hardware components, including the process of re-imaging the Storage Controller1.

The steps typically include:

Ensuring that all data is backed up before starting the re-imaging process.

Verifying the current system configuration and health status.

Following the specific instructions for re-imaging the Storage Controller as outlined in the guide.

Performing post-re-imaging tasks such as system verification and configuration as necessary.

It is important to follow the guide closely to avoid any potential issues during the expansion process1.

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

In preparation for a dual-to-quad online cluster expansion, the active cluster cabling should be validated using the Easy-Install menu. This menu provides a guided and automated way to ensure that all cabling is correctly connected and verified, minimizing the risk of errors and ensuring a smooth expansion process.
