The two copies of a SyncMirror volume are called_______. Each______is a physicalcopy of the same file system and consists of one or more RAID groups.

In NetApp ONTAP, SyncMirror technology provides data protection by creating two identical, synchronously updated copies of an aggregate or a traditional volume. These two physical copies are called plexes. Each plex is a complete physical instance of the file system, containing its own set of RAID groups. This configuration ensures that if one plex fails, the other can continue serving data without interruption, providing high availability and disaster recovery.

B. volumes, volume: The entire logical entity being mirrored is the volume. The physical copies that constitute the mirrored volume are called plexes, not volumes.

C. qtrees, qtree: A qtree is a logical partition within a volume used for management purposes like quotas, not a physical copy of the entire volume.

D. snapshots, snapshot: A Snapshot is a point-in-time, read-only image of a volume for backup and recovery, not a real-time, synchronously mirrored copy.

1. NetApp ONTAP 9 Data Protection Guide: In the section "How SyncMirror works

" it states

"A mirrored aggregate consists of two copies of the same file system. These copies are called plexes. Each plex is a physical copy of the file system and consists of one or more RAID groups." (Search for "How SyncMirror works" in the guide for ONTAP 9.7 or later).

2. NetApp ONTAP 9 Concepts Guide: Under the "Aggregates" section

when describing mirrored aggregates

the documentation specifies

"A mirrored aggregate has two plexes

or copies

of the same data." (Search for "mirrored aggregate" in the guide for ONTAP 9.7 or later).

3. NetApp Technical Report TR-4742: FlexGroup and FlexVol Best Practices: In the "SyncMirror" section

it clarifies

"SyncMirror provides synchronous mirroring of aggregates or traditional volumes. A mirrored aggregate or volume consists of two copies

called plexes." (Page 16).
