Estimating aggregate size for synchronous SnapMirror destination volumes

For synchronous replication of volumes using SnapMirror, the aggregates that contain destination volumes should have enough free space to store the NVLOG data.

Before you begin

You must have ascertained the model name of the system that is the synchronous SnapMirror source.


  1. Determine the size of the source system NVRAM.
    For information, see the Hardware Universe.
  2. Multiply the NVRAM size by 20 to determine the estimated free space size.
    2 GB times 20 is 40 GB; therefore, 40 GB of free space is required on the aggregate containing the destination volume.
