EMC Dell XtremIO Design Achievement 認定 D-XTR-DS-A-24 試験問題 (Q59-Q64):
質問 # 59
Which XtremlO X2 hardware component provides a backup power source to save journaling data during an unplanned emergency shutdown?
- A. NVRAM
- B. SuperCap
- C. BBU
- D. PSU
正解:B
解説:
In the event of an unplanned emergency shutdown, the XtremIO X2 hardware component that provides a backup power source to save journaling data is the SuperCapacitor (SuperCap). The SuperCap is designed to maintain power to the system long enough to ensure that all in-flight writes are committed to non-volatile memory, preserving data integrity.Unlike a battery backup unit (BBU) which may provide power for a longer duration, the SuperCap is specifically designed for short-term power retention to protect data during transient power interruptions1.
References:
* The User Guide for XtremIO, which includes power down and power up procedures, would typically detail the role of the SuperCap in emergency shutdown scenarios1.
* Additional information on the hardware components and their functions can be found in the Reference Architecture Guide for Dell EMC XtremIO2.
質問 # 60
Which statement is accurate about deduplication on an XtremlO array?
- A. As the deduplication ratio increases, bandwidth increases while latency increases
- B. As the deduplication ratio decreases, bandwidth decreases while latency increases
- C. As the deduplication ratio decreases, bandwidth increases while latency decreases
- D. As the deduplication ratio increases, bandwidth increases while latency decreases
正解:D
解説:
Deduplication on an XtremIO array is a process where redundant data blocks are identified and only unique data is stored. This results in a reduction of the physical storage required, which is referred to as the deduplication ratio. As the deduplication ratio increases, meaning more redundant data is eliminated, the bandwidth effectively increases because less data needs to be transferred over the network.Additionally, latency decreases because the system has to process fewer data blocks, leading to faster response times1.
References:
* The Dell EMC XtremIO X2: Next-Generation All-Flash Array document explains that XtremIO's in-memory deduplication is global across the entire cluster, which means that only unique data is written to the SSDs.This inline deduplication not only saves significant capacity but can also improve performance1.
* The Introduction to XtremIO X2 Storage Array document details how the XtremIO X2 Storage Array automatically reduces (deduplicates and compresses) data on the fly, as it enters the system, which reduces the amount of data written to flash, improving the longevity of the media and driving down cost2.
質問 # 61
What is the recommended execution throttle setting for Windows, Linux, and VMware for Qlogic adapters?
- A. 0
- B. 1
- C. 2
- D. 3
正解:C
解説:
The recommended execution throttle setting for Qlogic adapters, when used with Windows, Linux, and VMware, is typically set to the maximum value to allow for the greatest throughput and performance. The execution throttle setting determines the maximum number of outstanding I/O operations that can be queued to the storage controller.For Qlogic Fibre Channel adapters, especially when the HBA speed is 8GBs or over, the execution throttle can be set to 65,5351. This high setting is used to ensure that the storage array can handle a large number of concurrent I/O requests, which is beneficial in environments with high-performance requirements.
References:
* Dell community discussions on Qlogic Fibre Channel adapter settings1.
* Knowledgebase articles and documentation on Dell EMC's official website2.
質問 # 62
What should the I/O size be set to in a VMware VDI solution utilizing VAAI XCOPY on XtremIO?
- A. 256 kB
- B. 16 kB
- C. 4 MB
- D. 256 MB
正解:A
解説:
In a VMware VDI solution utilizing VAAI XCOPY on XtremIO, the I/O size should be set to 256 kB.This setting is recommended to optimize the performance of the storage array during XCOPY operations, which are used to offload the copying of data within the storage array to the array itself, freeing up host resources1.
References:
* The Dell support knowledge base article on using a VAAI claim rule to set the XCOPY size when using XtremIO for ESXi hosts recommends setting the XCOPY system value to 256 kB for XtremIO arrays1.
* Additional information on VAAI XCOPY and its configuration can be found in the "Introduction to XtremIO X2 Storage Array" document, which provides insights into the system features that support such operations2.
質問 # 63
A customer's environment is expected to grow significantly (more than 150 TB physical capacity) over the next year. Which solution should be recommended?
- A. Start with a four X-Brick X2-S cluster and add additional X2-S X-Bricks as needed
- B. Start with X2-R cluster and add additional X2-R X-Bricks as needed
- C. Start with X2-S cluster and add additional X2-S X-Bricks as needed
- D. Start with X2-R cluster and add additional X2-S X-Bricks as needed
正解:B
解説:
For environments expected to grow significantly (more than 150 TB physical capacity), it is better to start with an X2-R cluster and add additional X2-R X-Bricks as needed. X2-R configurations are designed for a variety of use cases and can handle larger capacities and high-performance requirements.
