- seed node
- A configured initial contact point.
- File Accesser Device
- New appliance type where the collection of NAS interface services runs including the NFS server and metadata management services.
- File Server Pool
- Collection of File Accesser Devices that are configured identically and participate in High Availability failover/failback pairs.
- File System
- Logical unit that encompasses a collection of File data and metadata. Each File System is mapped to a unique vault where file data is stored.
- Share
- Equivalent to the concept of an NFS export. Connecting to Shares via an NFS client takes the
form:
hostname:/fs/file_system/share_name - Site
- Manager concept to group devices within a physical location. File Accesser Devices that are within the same site should also share physical deployment locations. The Site designation is used internally by the metadata database. Performance is affected if all File Accesser Devices that are defined in the same Site are not deployed together in a low latency environment. All File Accesser Devices in the same Site participate in a unified device cluster for metadata storage.
