Question 8

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?

Accepted Answer

D

Explanation: 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.

Question 13

DRAG DROP 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? .

Accepted Answer

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.
