EMC Dell XtremIO Design Achievement Sample Questions (Q17-Q22):

NEW QUESTION # 17
Which disk format should be used for ESXi Disks provisioned by XtremIO?

  • A. Thick
  • B. Zeroed thick
  • C. Eager zeroed thick
  • D. Thin

Answer: C

Explanation:
For ESXi disks provisioned by XtremIO, the recommended disk format is 'Eager Zeroed Thick'. This format is preferred because it allocates all the space required for the disk at the time of creation and zeroes out any previous data on the physical media. Compared to other formats, 'Eager Zeroed Thick' provides better performance due to the pre-zeroing of the disk space, which helps in avoiding any latency that might occur during write operations as there is no need to zero out blocks before writing new data.
References:
* While the specific Dell XtremIO Design document was not available, the general best practice for high-performance storage solutions like XtremIO is to use 'Eager Zeroed Thick' provisioning for VMs running on VMware ESXi to ensure optimal performance1.
* Additional information on disk provisioning and best practices can be found in VMware's official documentation and Dell EMC's storage configuration guides2.


NEW QUESTION # 18
Which values are required to enter a generic workload into the XtremIO Sizing Tool?

  • A. Bandwidth, I/O size, and latency
  • B. IOPs, bandwidth, and latency
  • C. Capacity, IOPs, and Read ratio
  • D. IOPs, I/O size, and bandwidth

Answer: D

Explanation:
When entering a generic workload into the XtremIO Sizing Tool, the required values are IOPs, I/O size, and bandwidth. These parameters are essential for accurately sizing the storage system to ensure it can handle the expected workload. IOPs (Input/Output Operations Per Second) measure the number of read/write operations the storage system can perform in a second. I/O size refers to the size of each read/write operation, and bandwidth is the total amount of data that can be transferred in a given time frame.
References:
* The XtremIO Performance Documents discuss different workload testing parameters, including I/O size and limits, which are relevant to sizing the array1.
* The Dell XtremIO Design Achievement document outlines the critical components and best practices for designing solutions with XtremIO and X2 storage systems, which would include considerations for workload sizing2.


NEW QUESTION # 19
Which slot on a physical XtremIO X2 XMS holds the server's boot disk?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: C

Explanation:
The Dell XtremIO X2 XMS is designed with a specific slot for the server's boot disk. According to the documentation and specifications provided by Dell, the boot disk is located in a designated slot within the system.While the exact slot number is not explicitly mentioned in the snippets provided, the Dell XtremIO design documents, such as the support documentation1, technical whitepapers2, and specification sheets345, contain detailed information about the system architecture and component layout, including where the boot disk is situated.
For a verified and accurate answer, one should refer to the official Dell XtremIO design documents, which provide a comprehensive overview of the system, including detailed diagrams and descriptions of the hardware components and their respective slots. These documents are accessible through Dell's official support page or technical resources related to the XtremIO X2 product line.


NEW QUESTION # 20
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?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: A

Explanation:
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 to1281.
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.


NEW QUESTION # 21
Which performance monitoring utility can be used for data gathering on Windows?

  • A. PerfMon
