VSP One SDS Block consists of a storage cluster, a protection domain, fault domains, and storage nodes.

The internal configuration of VSP One SDS Block is shown below.

Storage cluster
VSP One SDS Block is what multiple storage nodes are called as a single virtual storage system.
Protection domain
Configuration to limit the scope of impact in the event of a storage node failure, a network failure between storage nodes, etc. All you have to do is set the name in setup. The number of protection domains is fixed by 1.
Fault domain (availability zone)
A group of storage nodes located in a single availability zone. The number of fault domains is 1, since the storage nodes comprising a cluster can only be located in a single availability zone.
For details about fault domains, see Settings and functions for fault tolerance supported by VSP One SDS Block.
Spread placement group
A group of EC2 instances, each deployed on different hardware in the AWS data center.
For details about spread placement groups, see Settings and functions for fault tolerance supported by VSP One SDS Block.
Storage node
A generic name of EC2 instances that make up VSP One SDS Block and process groups of VSP One SDS Block software running on those EC2 instances. This node is set up by using the setup operation.
Internode network
Network of storage nodes. Used to communicate user data and management information between storage nodes.
