Question No. 1

A customer is using a third party RESTful API client to create a series of new objects on an XtremlO cluster for use with their SQL application. Which HTTP method should be

used to create the objects needed for integration with the SQL application?

Show Answer Hide Answer
Correct Answer: A

In RESTful API design, the HTTP method used to create new resources or objects is POST. This method is utilized when the client needs to send data to the server to create a new entity. For example, when integrating with an SQL application and creating new objects on an XtremIO cluster, using a POST request with the appropriate payload will instruct the server to create the new resources as specified1.


A well-designed REST API implements CRUD operations using different HTTP methods, with POST being the method for Create operations1.

The Dell Technologies Developer Portal provides resources and documentation on REST APIs, including the methods used for various operations2.

Question No. 2

An XtremlO administrator has a cluster consisting of two X2 X-Bricks in production. The administrator plans to expand the cluster to a total of four X2 X-Bricks.

How many snapshots and volumes can the newly upgraded XtremlO cluster support?

Show Answer Hide Answer
Correct Answer: D

An XtremIO cluster's ability to support snapshots and volumes scales with the number of X-Bricks in the cluster. According to the documentation, an XtremIO X2 cluster can support up to 32K objects (root volumes + snapshots) per cluster1. Therefore, with the expansion from two to four X2 X-Bricks, the cluster would be able to support up to 32,768 snapshots and volumes.


The Dell EMC XtremIO X2: Next-Generation All-Flash Array document states the infrastructural scale supporting up to 32K objects per cluster1.

Additional information on the scalability and performance of XtremIO X2 clusters can be found in the Introduction to XtremIO X2 Storage Array document2.

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

Question No. 3

A customer has Microsoft Windows servers running Microsoft Multipath IO (MPIO). Which path selection policy should be set for optimal performance when connected to an XtremlO cluster?

Show Answer Hide Answer
Correct Answer: A

For Microsoft Windows servers running MPIO, the optimal path selection policy when connected to an XtremIO cluster is Round Robin. This policy allows for load balancing across all available paths by distributing I/O evenly, which can lead to better performance and utilization of the storage resources. The Round Robin policy ensures that no single path is overloaded with I/O requests, which helps in maintaining consistent performance levels1.


The Dell EMC SC Series: Microsoft Multipath IO Best Practices document provides insights into the recommended path selection policies for optimal performance2.

Additional information on MPIO and path selection policies can be found in the Dell EMC knowledge base articles1.

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

Question No. 4

A customer has a workload with the following attributes:

. Generates 500,000 IOPs

. Maximum bandwidth of 14 GB/s

Which XtremlO X2 solution should be recommended to the customer?

Show Answer Hide Answer
Correct Answer: A

To accommodate a workload that generates 500,000 IOPS with a maximum bandwidth of 14 GB/s, the recommended XtremIO X2 solution would be 4 X-Bricks. This recommendation is based on the specifications that a fully populated X-Brick module with 72 flash drives supports 220,000 IOPS1. Therefore, to support 500,000 IOPS, more than two X-Bricks are required. Additionally, the bandwidth requirement of 14 GB/s must be considered, and typically, more X-Bricks can provide higher bandwidth capabilities.

Question No. 5

A customer's environment is configured as follows:

. Dual X-Brick cluster

. 8 ESXi hosts with 2 Emulex HBAs

. Each ESXi hosts has 8 LUNs

. Each LUN is visible through 4 paths

What should be the LUN queue depth setting per path?

Show Answer Hide Answer
Correct Answer: A

The LUN queue depth setting per path in a customer's environment configured with a dual X-Brick cluster, 8 ESXi hosts with 2 Emulex HBAs, each ESXi host having 8 LUNs, and each LUN visible through 4 paths, should be set to 1281.

This is based on the best practice recommendation for Emulex HBAs in an XtremIO environment, as mentioned in the Dell Community1. The LUN queue depth on the Emulex HBA should be set to 1281. However, this setting might need to be adjusted based on the specific storage environment and the other storage arrays that are being used12.
