The appliance contains hardware RAID 6 controllers and inherently does striping with dual parity across disks on the storage shelves for high performance and data durability. Selecting other layouts such as mirrored or erasure coding layout for data protection is not necessary. As a best practice, for backup, archival and long-term retention use cases, it is recommended to configure the Access Appliance using defaults such as clustered file system, simple layout, and block size of 8 KB. For additional performance, the layout can be configured to be stripe.
To maintain the stripe performance, when growing the storage pool, the volumes must be added in multiples of the stripe columns, and thus, it is advisable to plan or size the system appropriately.
