• A SolidFire storage cluster
• An Amazon S3 object store
• An OpenStack Swift object store
When you restore volumes from OpenStack Swift or Amazon S3, you need manifest information from the
original backup process. If you are restoring a volume that was backed up on a SolidFire storage system, no
manifest information is required.
Protection domains
A protection domain is a node or a set of nodes grouped together such that any part or even all of it might fail,
while maintaining data availability. Protection domains enable a storage cluster to heal automatically from the
loss of a chassis (chassis affinity) or an entire domain (group of chassis).
A protection domain layout assigns each node to a specific protection domain.
Two different protection domain layouts, called protection domain levels, are supported.
• At the node level, each node is in its own protection domain.
• At the chassis level, only nodes that share a chassis are in the same protection domain.
◦
The chassis level layout is automatically determined from the hardware when the node is added to the
cluster.
◦
In a cluster where each node is in a separate chassis, these two levels are functionally identical.
You can manually enable protection domain monitoring using the NetApp Element Configuration extension
point in the NetApp Element Plug-in for vCenter Server. You can select a protection domain threshold based on
node or chassis domains.
When creating a new cluster, if you are using storage nodes that reside in a shared chassis, you might want to
consider designing for chassis-level failure protection using the protection domains feature.
You can define a custom protection domain layout, where each node is associated with one and only one
custom protection domain. By default, each node is assigned to the same default custom protection domain.

Double Helix high availability
Double Helix data protection is a replication method that spreads at least two redundant copies of data across
all drives within a system. The “RAID-less” approach enables a system to absorb multiple, concurrent failures
across all levels of the storage system and repair quickly.
