EMC E20-526 Dumps

You have been asked to design an XtremIO storage array solution that will be used for two large applications workloads. One overload will generate approximately 150,000 write IOPs with an average 4 kB I/O size. The second write workload will have an average I/O size of 128 kB and will generate approximately 2 GB/s of throughput.

At a minimum, how many X-Bricks are needed in a single cluster to meet this requirement?

At which point is data compressed when a host sends data to the XtremIO storage system?

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

A customer has decided to use VMware Horizon View as their desktop virtualization technology. Their VDI environment will consist of XtremIO storage and ESXi hosts. They are looking for increased speed and low latencies while performing file copy operations.

What should the setting for VAAI XCOPY I/O size be set to in order to achieve this requirement?

Refer to the exhibit.

A customer has a VMware Horizon View environment with the following characteristics:

• One X-Brick XtremIO cluster
• 100% read during a boot storm
• 8K read/writes

What is the maximum recommended number of VDIs the XtremIO cluster can support during a boot storm?

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?

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?

A customer has a large ESX server environment they are considering deploying to XtremIO for a VDI implementation. To determine a baseline of the environment, you are proceeding with documenting each server’s CPU, NIC, and disk utilization statistics. The customer has provided you with direct CLI access to the servers to conduct this assessment.

Which utility should be used to monitor these performance parameters?

When installing a physical XtremIO Management Server (XMS) station, which requirement must be met?

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?
