質問 # 20
In a fully-populated Data Protection Group (DPG) with sufficient capacity, how many disk drives need to fail sequentially to stop the XtremIO X2 data services?
- A. 0
- B. 1
- C. 2
- D. 3
正解：A
解説：
In a fully-populated Data Protection Group (DPG) within an XtremIO X2 array, the system can tolerate up to six disk drives failing sequentially without stopping data services. This is due to the XtremIO X2's ability to maintain operations with double SSD failure protection1. The seventh drive failure would be the point at which the data services are stopped because the system would no longer be able to maintain the required level of redundancy for data protection.
The DPG is designed to handle multiple SSD failures by entering different states of degradation:
Healthy: Double parity protection.
Single Degraded: Single parity protection.
Double Degraded: No parity protection.
Failed: Data Loss.
When the first SSD fails, the system automatically initiates a DPG rebuild to restore double parity protection. If a second SSD fails before the rebuild is complete, the DPG's usable capacity drops by the capacity of one SSD, but it still maintains single parity protection. Only after the failure of a seventh SSD would the DPG enter a failed state, resulting in the cessation of data services2.

When using the Microsoft VSS Framework with an XtremlO cluster to manage snapshot backups, what is the correct sequence of steps to create a Windows volume backup?
正解：
解説：
Explanation:
The correct sequence of steps to create a Windows volume backup using the Microsoft VSS Framework with an XtremIO cluster is as follows:
* Requestor interacts with the VSS service to start the backup.
* VSS service sends a Freeze request to the Writer.
* Provider creates an XVC of the file system and exposes the volume to the host.
* VSS service sends a Thaw request to the Writer.
* Requestor uses the XVC to back up the content of the volume.
* The Requestor, typically a backup application, initiates the process by interacting with Microsoft's Volume Shadow Copy Service (VSS) to commence a snapshot backup.
* The VSS service then issues a Freeze request to its Writers, which are responsible for ensuring data consistency for applications during backups.
* An XtremIO Provider, which interfaces between the XtremIO storage and VSS, creates an XtremIO Virtual Copy (XVC) of the file system. This copy is then made accessible to the host system for backup purposes.
* After the XVC is created, the VSS sends a Thaw request to the Writers, allowing them to resume normal operations while maintaining data integrity.
* Finally, the Requestor uses the XVC to back up the content of the volume, ensuring a consistent and recoverable backup is made.
Please note that this sequence is based on the standard operation of Microsoft VSS with storage systems like XtremIO and should be verified against the most current Dell XtremIO Deploy Achievement documentation for any updates or specific instructions related to your environment.

質問 # 39
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, Eager Zero
- C. Thin Provisioned
- D. Thick Provisioned, Lazy Zero
正解：B
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.
