Which ONTAP technology provides the best performance improvement for teams across multiple sites accessing the same ONTAP volume?

• A. SnapVault for data backup
• B. FlexClone for instant writable copies
• C. FlexCache to serve read data locally
• D. SnapMirror for real-time synchronization

Answer: (C)

FlexCache is built to speed up read access for data that is shared across multiple sites by bringing the data closer to users. When teams at different locations access the same ONTAP volume, much of the workload is reads. FlexCache places a read cache at each remote site, so those reads can be served locally instead of traveling over the WAN to the origin cluster. This dramatically lowers latency and boosts throughput for multi-site access, while writes continue to go to the origin to keep data consistent. The other options don’t offer this kind of read-local-caching benefit. SnapMirror focuses on real-time or near-real-time replication for disaster recovery and site availability, not reducing remote read latency. SnapVault is for backups, not active performance for shared volumes. FlexClone creates instant writable copies for testing or development, not multi-site read optimization.
