Question No. 1

You need to design an Oracle solution for a customer. Which XtremlO best practices should be used in Oracle environments?

Show Answer Hide Answer
Correct Answer: D

When designing an Oracle solution for a customer using XtremIO, it's important to consider the best practices for performance and efficiency.

Option OD, ''Allocate multiple LUNs per host, Use Thin formatting on the ESXi'', is a recommended best practice for Oracle environments12.

Allocating multiple LUNs per host can help distribute the I/O load more evenly across the storage system, which can improve performance1. This is particularly important in Oracle environments, where there can be a high level of concurrent I/O activity1.

Using Thin formatting on the ESXi is also recommended. Thin provisioning is a storage provisioning method that optimizes the efficient use of available space. For a thin virtual disk, ESXi provisions the entire space required for the disk's current and future activities, but the thin disk uses only as much storage space as the disk needs for its initial operations3. If the disk requires more space, it can expand into its entire provisioned space3.

Question No. 2

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. 3

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. 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?

Show Answer Hide 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.

Question No. 5

Which host OS supports both 512 bytes and 4 KB XtremIO logical block (LB) volumes?

Show Answer Hide Answer
Correct Answer: A

The Dell EMC XtremIO X2 storage array offers flexible scaling options with building blocks called X-Bricks1. The system can start with a single X-Brick and scale up to 72 SSDs for a single X-Brick1. When additional performance and capacity are required, the system can be expanded by adding additional X-Bricks1.

Among the options provided, VMware is the host OS that supports both 512 bytes and 4 KB XtremIO logical block (LB) volumes23. VMware vSphere 6.7 and later versions support both 512-byte and 4K logical block sizes23. This is because VMware ESXi detects and registers the 4Kn devices and automatically emulates them as 512e3.

The other options, while they may be part of the overall process, are not specifically known to support both 512 bytes and 4 KB XtremIO logical block (LB) volumes:

Linux typically supports multiple file system block sizes of 512, 1024, 2048, and 40964. However, it's not specifically mentioned that it supports both 512 bytes and 4 KB XtremIO logical block volumes5.

IBM AIX also supports multiple file system block sizes of 512, 1024, 2048, and 40966. But again, it's not specifically mentioned that it supports both 512 bytes and 4 KB XtremIO logical block volumes7.

HP-UX does not specifically mention support for both 512 bytes and 4 KB XtremIO logical block volumes89.

Therefore, the verified answer is A. VMware, as it is the host OS that supports both 512 bytes and 4 KB XtremIO logical block (LB) volumes23.
