Question No. 1

You have been requested to connect to the TECH port of a physical XtremIO X2 XMS by Global Technical Support. Which port should the service machine be connected to on the server?

AUSB-MIDDLE

BUSB-BOTTOM

CUSB-TOP

DMGMT ETHO

Show Answer

Correct Answer: D

When Global Technical Support requests a connection to the TECH port of a physical XtremIO X2 XMS, the service machine should be connected to the MGMT ETH0 port on the server. This port is typically used for management purposes and allows for the necessary communication between the service machine and the XtremIO X2 XMS for technical operations and support.

The Dell EMC support document outlines issues related to the management network configuration failure and mentions the physical XMS management port, which is relevant to the TECH port connection1.

Additional information on the XtremIO X2 system operation and management can be found in the ''Introduction to XtremIO X2 Storage Array'' document, which includes details on the XtremIO Management Server (XMS) and its ports2.

Question No. 2

What is a benefit of XtremIO All Flash arrays?

ACost per GB is the same as spinning disk

BCost per GB is lower than spinning disk

CCost per I/O per GB is the same as spinning disk

DCost per I/O per GB is lower than spinning disk

Show Answer

Correct Answer: D

XtremIO All Flash arrays provide a significant benefit in terms of cost per I/O per GB when compared to traditional spinning disks. This is due to the higher performance and efficiency of flash storage, which delivers faster data access speeds and better I/O rates. As a result, the cost per I/O operation, when spread over the total capacity of the storage (GB), is lower for all-flash arrays. This efficiency translates into better overall value, especially for workloads that require high I/O throughput1.

It is a common understanding that all-flash arrays, like XtremIO, offer better performance and efficiency compared to spinning disks, which results in a lower cost per I/O per GB1.

The ''Introduction to XtremIO X2 Storage Array'' document from Dell Technologies highlights the efficiency of the storage array, which contributes to reducing the $/GB cost of storage2.

Additional data from industry sources supports the notion that all-flash storage can be more cost-effective in the long run due to operational cost reductions and lower total cost of ownership (TCO) over time1.

Question No. 3

A storage administrator is configuring SAN switches and zoning to connect a four X-Brick XtremlO array. A VMware ESXi server is hosted on a blade chassis with 16 HBA ports.

In addition, the SAN consists of two separate SAN switches.

What is the recommended XtremlO best practice for zoning?

AFirst Storage Controllers' HBA ports to the first switch
Second Storage Controllers' HBA ports to the second switch
Multipath all host ports to single LUNs per zone

BTwo HBA connections per host
Single initiator/multiple targets per zone
Maximum of 16 paths for each device
Host connected to each SAN switch

CSingle Storage Controller HBA port to the first switch
Single Storage Controller HBA port to the second switch
Single initiator/multiple targets per zone
Maximum of 4 paths for each LUN per zone

DTwo HBA connections per host connected to a single switch
Multiple initiators/multiple targets per zone
Maximum of 4 paths for each LUN per zone

Show Answer

Correct Answer: B

For a four X-Brick XtremIO array, the recommended best practice for zoning in a SAN environment with VMware ESXi servers is to have two HBA connections per host, with each host connected to both SAN switches. This configuration allows for redundancy and high availability. The zoning should be set up with a single initiator (the HBA on the host) to multiple targets (the storage controllers' HBA ports) per zone. This ensures that each host has multiple paths to the storage, allowing for failover and load balancing. The maximum number of paths for each device should be 16 to prevent exceeding the path limits and to maintain optimal performance1.

Dell Technologies community discussions on XtremIO Zoning Best Practices provide insights into the recommended zoning configurations for different XtremIO setups1.

The Host Configuration Guide for XtremIO, which can be found on the Dell EMC support site, offers detailed instructions on zoning best practices for XtremIO storage arrays2.

Question No. 4

A customer has a complex virtualized environment and wants to see a topology view from virtual or physical hosts down to the storage array volumes to identify application to

storage dependencies.

Which Dell EMC product provides this solution?

ATechnician Advisor

BViPR SRM

CXtremIO VAAI plug in

DAppSync

Show Answer

Correct Answer: B

ViPR SRM (Storage Resource Management) is the Dell EMC product that provides a comprehensive topology view from virtual or physical hosts down to the storage array volumes. This tool is designed to help customers manage complex virtualized environments by offering insights into application-to-storage dependencies. ViPR SRM delivers detailed reporting and analytics, which can be used to optimize storage performance and capacity planning1.

The Introduction to XtremIO X2 Storage Array document provides information on the system features and management tools available for XtremIO arrays, which includes details on how ViPR SRM can be used to visualize and manage the storage infrastructure1.

Additional resources on the Dell EMC support site offer documentation and guides on how to effectively use ViPR SRM for storage resource management2.
