EMC Dell XtremIO Deploy Achievement 認定 D-XTR-DY-A-24 試験問題 (Q30-Q35):
質問 # 30
A customer's environment consists of four XtremlO X1 clusters. Two clusters are running XtremIO software 4.0.4-41 and two clusters are running XtremIO software 3.0.3-11.
What is the minimum number of XMS servers required in this environment?
- A. 0
- B. 1
- C. 2
- D. 3
正解：A
解説：
In an environment with multiple XtremIO X1 clusters running different versions of XtremIO software, the minimum number of XtremIO Management Servers (XMS) required is determined by the compatibility and management requirements of the clusters.
Compatibility Check: Verify the compatibility of XMS with different versions of XtremIO software. An XMS can manage clusters running the same major version of software.
Management Requirements: Assess the management requirements for the clusters. Each XMS can manage multiple clusters, but there may be limitations based on the software version and scalability limits.
Scalability Limits: Consider the scalability limits of the XMS. For example, an XMS managing multiple clusters may have a global limit on the number of volumes it can manage across all clusters1.
Determine the Minimum Number: Based on the above factors, determine the minimum number of XMS servers required. In this case, since there are two distinct software versions (4.0.4-41 and 3.0.3-11), at least two XMS servers would be needed-one for each software version group.
Official Documentation: Consult the official Dell XtremIO Deploy Achievement document for specific guidelines and instructions. The document will provide the authoritative steps and references for setting up and managing the XMS in a multi-cluster environment.
In conclusion, for four XtremIO X1 clusters with two different software versions, a minimum of two XMS servers is required-one for the clusters running software 4.0.4-41 and another for those running software 3.0.3-11. This ensures proper management and compatibility across the clusters.
質問 # 31
What is the total number of power connectors that must be available in a customer rack for an XtremIO X2 dual X-Brick cluster configuration without a physical XMS installed?
- A. 0
- B. 1
- C. 2
- D. 3
正解：C
解説：
For an XtremIO X2 dual X-Brick cluster configuration without a physical XMS installed, the total number of power connectors required in a customer rack is 8. This is based on the system specifications which state that a 2 Brick Cluster requires 16 x IEC C14 power sockets1. Since the physical XMS would typically require additional power sockets, and it is not included in this configuration, the total number of power connectors needed would be less than the specified 16.
Here's the breakdown:
Each X-Brick in a dual X-Brick configuration would require power for its controllers and DAEs.
The InfiniBand switches included in a multi X-Brick system would also require power.
Without the physical XMS, which would normally need its own power connectors, the total comes down to 8 connectors required for the dual X-Brick setup1.
質問 # 32
You are creating a virtual disk for a VMware VM running on vSphere 6.5. The VM will reside on a datastore provisioned from an XtremIO volume. You want to ensure proper performance and capacity usage.
How should the disk be presented to the guest?
- A. Raw Device Mappings
- B. Thick Provisioned, Lazy Zero
- C. Thick Provisioned, Eager Zero
- D. Thin Provisioned
正解：C
解説：
For a VMware VM running on vSphere 6.5 that will reside on a datastore provisioned from an XtremIO volume, the disk should be presented to the guest as Thick Provisioned, Eager Zero (EZT). This is recommended for the best performance and efficient capacity usage.
Thick Provisioning, Eager Zero: This type of provisioning allocates all the space required for the virtual disk upfront and marks all the space as zeroed. This means that the physical space is reserved and zeroed on the storage array, ensuring that the VM does not have to wait for space to be allocated or zeroed before writing data. This can lead to better performance, especially for I/O-intensive applications1.
XtremIO and EZT: XtremIO arrays are particularly well-suited for EZT because they use inline deduplication and never actually have to zero out physical media. The metadata is kept in memory, and writes are journaled to memory before being saved to SSDs. XtremIO uses VAAI (vStorage APIs for Array Integration) to accelerate zeroing operations, so hosts do not have to write zeros, and the allocation of EZT virtual disks is a very quick operation1.
Performance Considerations: For applications that require low latency, such as databases, using EZT reduces overall latency for the application. Since XtremIO arrays are designed to handle such operations efficiently, the initial zeroing process with EZT, which could take a long time on traditional storage architectures, is significantly faster1.
In conclusion, for ensuring proper performance and capacity usage for a VM on vSphere 6.5 with an XtremIO volume, Thick Provisioned, Eager Zero is the recommended method of disk presentation.
質問 # 33
Which operational state of an XtremIO X2 NVRAM card will trigger SuperCap discharging?
- A. Power Restored
- B. Normal Operation
- C. Power Failure
- D. Data Secured
正解：C
解説：
In the event of a power failure, the XtremIO X2 system's NVRAM (Non-Volatile Random Access Memory) card will initiate the discharging of the SuperCapacitor (SuperCap). The SuperCap is designed to provide enough power to the NVRAM card to allow it to write any data in transit to a non-volatile storage medium, ensuring data integrity and preventing loss1. This process is a critical part of the XtremIO X2's data protection mechanism during unexpected power interruptions.
質問 # 34
A systems administrator's VMware Horizon environment consists of 1000 linked clones. Based on best practices, what is the minimum number of datastores required to support this configuration connected to XtremIO?
- A. 0
- B. 1
- C. 2
- D. 3
正解：B
解説：
When configuring a VMware Horizon environment with 1000 linked clones connected to an XtremIO storage system, the minimum number of datastores required to support this configuration, based on best practices, is four. This recommendation ensures optimal performance and manageability while avoiding overcommitment of resources.
The process for determining the minimum number of datastores involves:
Assessing Performance Needs: Evaluate the performance requirements of the linked clones, considering factors such as IOPS (Input/Output Operations Per Second) and throughput.
Understanding XtremIO Capabilities: Recognize that XtremIO's all-flash array provides high performance and low latency, which can support a large number of clones per datastore.
Considering VMware Best Practices: VMware's best practices suggest balancing the number of clones across multiple datastores to optimize performance and manageability1.
Calculating Datastore Requirements: For 1000 linked clones, dividing them across four datastores allows for sufficient distribution without exceeding the capabilities of the XtremIO system.
Implementing the Configuration: Create and configure the four datastores within the VMware Horizon environment, ensuring they are properly connected and recognized by the XtremIO storage system.
Monitoring and Adjusting: After implementation, continuously monitor the performance and capacity of the datastores, making adjustments as necessary to maintain optimal operation.
It's important to note that while four is the minimum recommended number based on best practices, the actual number may vary depending on specific environmental factors and requirements. Always refer to the latest official documentation and consult with Dell support for tailored advice.
