For a multi X-Brick XtremIO X1 cluster, each X-Brick requires one Battery Backup Unit (BBU) that provides protective power to both Storage Controllers within the X-Brick. Additionally, there are two BBU COM (communication) ports required, with one connected to each Storage Controller.This configuration ensures that in the event of a power failure, the BBU can maintain power to the Storage Controllers, allowing them to safely shut down and protect data integrity1.

The installation process would typically involve:

Installing the BBU in the designated slot within the X-Brick.

Connecting the BBU power cable to the power supply of both Storage Controllers.

Connecting a BBU COM port to each Storage Controller for communication and monitoring purposes.

This setup is crucial for maintaining the high availability and data protection standards that XtremIO systems are known for1.

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

The XtremIO Storage Array Site Preparation Guide is the document that provides detailed information about the environmental requirements, including temperature and humidity, for XtremIO storage systems.This guide is essential for ensuring that the site where the XtremIO system will be installed meets the necessary conditions for optimal operation and longevity of the equipment1.

The guide typically includes:

The acceptable temperature range for both operating and non-operating conditions.

The recommended humidity levels to prevent condensation and other moisture-related issues.

Guidelines for airflow and cooling to maintain the specified temperature and humidity levels.

It is important to adhere to these requirements to ensure the reliable performance of the XtremIO storage array and to avoid any potential environmental-related issues1.

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

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.

For uploading the XtremApp to the XtremIO Management Server (XMS), the recommended tool isWinSCP.WinSCP is a popular SFTP client and FTP client for Microsoft Windows that allows for secure file transfer between a local and a remote computer1. It is particularly useful for uploading files like XtremApp due to its graphical user interface, which simplifies the process of transferring files.

The steps for uploading the XtremApp to the XMS using WinSCP are as follows:

Download and install WinSCP on your local machine.

Open WinSCP and enter the XMS’s hostname or IP address, as well as the username and password.

Navigate to the XtremApp file on your local machine within the WinSCP interface.

Drag and drop the XtremApp file to the desired directory on the XMS.

Verify that the upload was successful by checking the file size and timestamp on the XMS.

This method is recommended in the Official Dell XtremIO Maintenance Achievement document as it provides a secure and reliable way to manage files on the XMS1.

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

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.

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

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 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.

A key feature of the XtremIO storage array is inline compression. This feature allows data to be compressed in real-time as it is written to the storage system, which helps to reduce storage footprint and improve storage efficiency without impacting performance.

ESRS (EMC Secure Remote Services) configuration verification is typically done using commands that check for system notifications and configurations.

The show-syslog-notifier command is used to verify the settings and configuration of syslog notifications, which is part of the ESRS setup.

This command helps in ensuring that the notifications are correctly configured and functioning as intended, allowing for remote monitoring and management.

For an XtremIO cluster to use FTPS (File Transfer Protocol Secure) for the Connect Home feature, the firewall ports that need to be opened are989 and 990.These ports are used for data connections and control connections under implicit security for FTPS1.

When using explicit security, FTPS can also use port 21, but since the question specifies FTPS for Connect Home, which typically uses implicit security, the correct ports are989 for data transmissionand990 for the control connection1. It’s important to ensure these ports are open to allow secure file transfer capabilities for the XtremIO cluster.
