When planning or sizing the Access Appliance as a long-term retention solution for FlashArray snapshots there are two factors:
- Capacity - how many snapshots can be stored
- Performance - how much workload can the storage platform handle.
The Veritas and Everpure account team will assist in the sizing of the appliance based on your requirements using these factors. Some parameters that might enter in the equation when estimating long-term storage requirements include:
- Volume of source data.
- Daily data change ratio
- Annual storage growth
- Data retention.
- Compression Ratio (how well your data compresses)
- Performance and/or service level requirements.
Some considerations when deploying and implementing FlashArray “Snap to NFS” include:
- Maximum number of offload targets per FlashArray: 1
- Maximum number of volume snapshots offloaded to NFS per FlashArray: 100,000
- Maximum number of volume snapshots on NFS per FlashArray: 200,000
- Maximum number of protection groups per FlashArray: 250
- Maximum number of FlashArray per NFS target (not NFS server): 4
