A NearStore system or storage appliance can operate as a secondary and primary system at the same time.

A NetApp storage system, including the product line formerly known as NearStore, operates using the ONTAP software. A fundamental architectural feature of ONTAP is its ability to manage storage resources, such as volumes, on a granular level. This allows a single storage appliance (or cluster) to perform multiple roles concurrently. It can serve some volumes as primary storage (active, read-write volumes serving data to clients and applications) while simultaneously using other volumes on the same system as secondary storage targets for data protection relationships like SnapMirror (disaster recovery) or SnapVault (backup). This multi-role capability enables efficient hardware utilization for both production workloads and data protection.

The "False" option is incorrect because it suggests a rigid, system-wide role limitation. In a NetApp environment, the designation of "primary" or "secondary" is not applied to the entire storage system but is a function of individual volumes and the data protection relationships configured for them.

1. NetApp ONTAP 9 Documentation

Data Protection Guide: In the "Data protection overview" section

the documentation explicitly states the capability of a single system to hold both primary and secondary data. It notes

"You can use the same cluster for the primary and secondary volumes

but this provides protection against data loss from volume or aggregate failure

not from site disaster." This directly confirms that a single system can operate in both roles simultaneously.

SnapMirror Configuration and Best Practices Guide for Clustered Data ONTAP: This report details the architecture of SnapMirror

which operates on a source-volume-to-destination-volume basis. Section 1.2

"SnapMirror Technology

" describes this relationship. The architecture does not impose a system-level restriction

meaning a system can be a source for some relationships and a destination for others

thereby acting as both primary and secondary.

Best Practices for SnapVault in Data ONTAP 7G and 8.0 7-Mode: This document

relevant to the era when "NearStore" was a prominent brand

describes the SnapVault relationship between a primary system (source of production data) and a secondary system (backup target). The relationship is defined between qtrees or volumes. The architecture allows a single Data ONTAP system to host primary volumes while also acting as a SnapVault secondary for other volumes

reinforcing the principle of multi-role operation.
