For a customer with an 80 TB database that will not benefit from compression and deduplication, and with no projected future growth, the minimum recommended XtremIO X1 offering would be the one that provides at least 80 TB of raw storage capacity.

Based on the options provided:

A. 20 TB 4 X-Brick model

B. 40 TB 4 X-Brick model

C. 10 TB 8 X-Brick model

D. 20 TB 6 X-Brick model

The most suitable option that meets the requirement of providing at least 80 TB of raw storage capacity would be B. 40 TB 4 X-Brick model. This is because each X-Brick in the XtremIO X1 system contributes to the total raw storage capacity, and with a 4 X-Brick model, each X-Brick would need to provide at least 20 TB to meet the 80 TB requirement. Since the 40 TB 4 X-Brick model offers 40 TB per X-Brick, it would exceed the required capacity, ensuring that the customer’s needs are met without any shortfall.

During the installation of an XtremIO X1 system, the document that should be used to identify the ports for IPMI (Intelligent Platform Management Interface) cable connections is the XtremIO Storage Array Hardware Installation and Upgrade Guide. This guide typically contains detailed information about the hardware components, including diagrams and descriptions of the ports, which are essential for correctly connecting the IPMI cables.

The process of identifying the correct IPMI ports usually involves the following steps:

Locate the Guide: Access the XtremIO Storage Array Hardware Installation and Upgrade Guide. This document is designed to provide instructions specifically related to the physical components of the XtremIO system.

Identify the Ports: Use the diagrams and descriptions within the guide to locate the IPMI ports on the XtremIO hardware. These ports are typically labeled and may be color-coded to help distinguish them from other ports.

Connect the Cables: Once the IPMI ports have been identified, connect the IPMI cables to these ports as per the instructions provided in the guide. Ensure that the connections are secure and that the cables are not obstructing any other components.

Verify the Connections: After connecting the cables, verify that the connections match the diagrams and descriptions in the guide. This step is crucial to prevent any issues related to incorrect cabling.

Reference Documentation: For the most accurate and up-to-date information, always refer to the latest version of the XtremIO Storage Array Hardware Installation and Upgrade Guide1. This ensures that any changes or updates to the hardware are taken into account during the installation process.

By following these steps and referring to the correct documentation, you can ensure that the IPMI cable connections are made correctly, which is vital for the remote management and monitoring of the XtremIO X1 system.

In XtremIO, snapshots are created efficiently using metadata rather than duplicating the actual data blocks. When a snapshot is made, it initially shares the same data blocks as its ancestor. When the first write occurs to a block in a snapshot, it triggers a Copy-On-First-Write (COFW) operation. This means the original data block is copied to a new location to preserve the integrity of the snapshot, ensuring that each snapshot reflects the data state at the moment of its creation.

This COFW operation ensures that the data remains consistent and unchanged for each snapshot, while allowing new writes to occur without impacting the original data or other snapshots. As a result, the first write to each snapshot impacts its ancestor by triggering a COFW operation.
