Data ONTAP GX: A Scalable Storage Cluster

Data ONTAP GX is a clustered Network Attached File server composed of a number of cooperating filers. Each filer manages its own local file system, which consists of a number of disconnected flexible volumes. A separate namespace infrastructure runs within the cluster, which connects the volumes into one or more namespaces by means of internal junctions. The cluster collectively exposes a potentially large number of separate virtual servers, each with its own independent namespace, security and administrative domain. The cluster implements a protocol routing and translation layer which translates requests in all incoming file protocols into a single unified internal file access protocol called SpinNP. The translated requests are then forwarded to the correct filer within the cluster for servicing by the local file system instance. This provides data location transparency, which is used to support transparent data migration, load balancing, mirroring for load sharing and data protectio...
