Each SnapVX source volume can also have up to 1024 SnapVX linked targets. There is no hard limit on the number of sessions in a single array. The total sessions within an array depend on the configured and available resources. Include snapshot use in the overall sizing and planning of new systems to ensure that each array is configured with required resources. After deployment, monitor system resources as usage grows. These best practice recommendations are applicable to all features and applications on a storage array and are not specific to snapshots.
