質問 # 34
Refer to the exhibit.
Refer to the Exhibit.
An XtremlO administrator is asked to provide a copy of a 25 TiB database to a group of users. Each user needs to have their own copy of the database in order to perform a variety of manipulations on the dat a. This process needs to be repeated every day of the week. The administrator is concerned about the time it will take to make the initial copy of the database and is investigating the use of snapshots of snapshots.
How does each snapshot impact its ancestor?
- A. Each first access to each snapshot will trigger a COFA from its ancestor
- B. Each first write to a block of the production volume will trigger a COFW to each child snapshot
- C. Each snapshot can be considered a unique volume and has no impact
on its ancestor - D. Each first write to each snapshot will trigger a COFW from its ancestor
正解：C
解説：
In the XtremIO environment, snapshots are treated as unique volumes that are independent of their ancestors. When a snapshot is created, it is essentially a point-in-time copy of the data from the source volume. These snapshots operate independently and do not affect the performance or data integrity of the original volume. Any changes made to a snapshot do not impact the ancestor volume, and vice versa. This allows for efficient use of storage resources and enables multiple users to work with their own copies of the database without affecting the original data.
The process of using snapshots of snapshots, also known as cascaded snapshots, is efficient in XtremIO due to the system's unique data reduction and copy data management (CDM) capabilities. Since only changes from the original are stored, it minimizes the additional storage space required for each user's copy of the database. This approach is particularly beneficial when the same process needs to be repeated daily, as it saves time and storage resources1.
