FPO pool file placement and AFM
For AFM home or cache, an FPO pool file that is written on the local side is placed according to the write affinity depth and write affinity failure group definitions of the local side.
When a file is synced from home to cache, it follows the same FPO placement rule as when written from the gateway node in the cache cluster. When a file is synced from cache to home, it follows the same FPO data placement rule as when written from the NFS server in the home cluster.
To retain the same file placement at AFM home and cache, ensure that each has the same cluster configuration and set the write affinity failure group for each file. If the home and cache cluster have different configurations, such as the disk number, node number, or fail group, then the data locality might be broken.
