Question 1

A customer has a VMware vSphere environment running Native Multipathing (NMP). Which path selection policy should be set for optimal performance when connected to an XtremIO cluster?

Accepted Answer

Round Robin is the recommended path selection policy for optimal performance with XtremIO clusters, as it balances the load across all available paths.

Question 3

A customer is considering a six brick dispersed cluster using 3×40U racks. The customer wants advice on racking the InfiniBand switches. Rack 1 (left) contains X-Bricks 1 and 2 Rack 2 (middle) contains X-Bricks 3 and 4 Rack 3 (right) contains X-Bricks 5 and 6 Which recommendation should be provided?

Accepted Answer

The InfiniBand switches should be installed in Racks 1 and 3 with a 1U placeholder between the X-Bricks. This will provide the best performance and scalability for the cluster.

Question 4

Refer to the Exhibit. A customer has the following XtremIO environment: Read/write ratio is 3:1 I/O size is 8K Write pattern is random Data is compressible If an application generates 100,000 IOPS of traffic, how many RPAs are needed to replicate the traffic from one XtremIO array to another XtremIO array over IP?

Accepted Answer

The answer of  Refer to the Exhibit. A customer...

Question 5

A customer has an existing Oracle environment they are considering moving over to XtremIO from VMAX for improved performance. The customer wants to know the expected deduplication and compression savings they can achieve with XtremIO. Which tool is appropriate for conducting this assessment?

Accepted Answer

The EMC MiTrend Tool is designed to analyze existing storage environments and provide insights into potential deduplication and compression savings when migrating to XtremIO.

Question 6

A customer is interested in purchasing XtremIO for their mission critical database applications that require the lowest possible response times. They have two data centers in which they want to introduce All-Flash arrays. However, they need a way to maintain true active/active access to all databases and application LUNs across both sites. What is the recommended solution to address the requirements?

Accepted Answer

VPLEX Metro with XtremIO is the recommended solution as it provides true active/active access to storage across two data centers, which is essential for maintaining high availability and low response times for mission-critical applications.

Question 7

What is considered typical performance for an XtremIO single X-Brick cluster?

Accepted Answer

The answer of What is considered typical performance for an...

Question 8

A customer's storage administration team wants to receive e-mail notifications when the XtremIO cluster detects an issue of major seventy. The customer has successfully configured and tested the e-mail server in the XtremIO GUI. However, the e-mail server is not receiving the expected notifications when major severity issues appear. What is the cause of this issue?

Accepted Answer

Alert definitions have not been defined. Without defining alert conditions, the system does not know which events should trigger notifications.

Question 9

A customer has a requirement to replicate their VDI to a newly purchased data center located 5 miles away. They require 10-day retention at each site and a continuous replication RPO. However, they want to have the same storage platform at each site. They have a limited budget but need to meet their requirements. Which solution should be recommended to the customer?

Accepted Answer

XtremIO and RecoverPoint provide continuous replication with the ability to maintain a 10-day retention period, and they can be deployed on the same storage platform at both sites, meeting the customer's requirements within a limited budget.

Question 10

How many management IP addresses are required on a single XtremIO storage controller?

Accepted Answer

Each XtremIO storage controller requires one management IP address for management and monitoring purposes.

Question 11

When using a 10 TB single X-Brick, what is the minimum amount of data that should be written during the Fill phase of the PoC Toolkit?

Accepted Answer

The minimum amount of data that should be written during the Fill phase of the PoC Toolkit for a 10 TB single X-Brick is 20 TB to ensure proper testing and validation of the system's performance and capacity.

Question 12

A customer currently uses XtremIO native remote replication with four RPAs and a 1 GB WAN link to asynchronously protect all production data. Management has decided that all data stored on the XtremIO must now be protected at the disaster recovery site by synchronous replication. How can this be achieved?

Accepted Answer

The answer of A customer currently uses XtremIO native remote...

Question 13

An administrator receives an error on an XtremIO array while performing snapshot refreshes to a production volume. What is a potential cause for this issue?

Accepted Answer

The error may occur if the volume was not unmounted on the host, as the host might still be accessing the volume, preventing the refresh operation.

Question 14

Which SCSI instructions are used to build a bitmap of the changes between the first snapshot and subsequent snapshots when RecoverPoint is used with XtremIO?

Accepted Answer

SCSI DIFF instructions are used to identify and build a bitmap of changes between snapshots in storage systems like RecoverPoint with XtremIO.

Question 15

A customer has a workload with the following attributes: Generates 250,000 IOPs 100 TB in logical capacity Read/Write ratio of 1:1 Random workload with 8 kB I/O size Deduplication ratio of 2:1 Compression ratio of 2:1 Which XtremIO solution should be recommended to the customer?

Accepted Answer

The workload requires a high IOPS capacity and significant storage space. With deduplication and compression, the logical capacity is reduced, but the IOPS requirement remains high. A 3×20 TB X-Brick configuration can handle the IOPS and provide sufficient storage after deduplication and compression.

Question 16

A storage administrator is adding both an XtremIO and third-party storage arrays to their existing infrastructure. The administrator is using ViPR SRM to monitor the environment. Which requirement is needed to implement this solution?

Accepted Answer

Each storage array needs its own Solution Pack in ViPR SRM to ensure proper monitoring and management of different types of storage systems.
