The first data Ontap borrowed a lot of code from one of the earliest Open source Unix BSD NET/2, including the TCP/IP stack, boot code, device driver, and later data Ontap from other Open source Unix. As for the command-line interface, which was developed independently by NetApp Unix, the WAFL file system and the RAID code and disk subsystem were developed for NetApp itself, so it was completely different from UNIX.

at first Dataontap there was no mode, NetApp acquired Spinnaker and then Dataontap and spinnaker software from FreeBSD to another operating system called Data Ontap GX, when the data ONTAP Update to version 8.0, NetApp unified the two version number, and the original Dataontap called 7 mode, the later data Ontap GX is called cluster mode, referred to as C mode.

NetApp has been developing 7 mode and cluster mode two operating systems since the new Dataontap cluster mode is not fully functional, but as NetApp aggressively promotes and develops cluster mode, it is believed that it will soon Stop Development 7 mode only cluste mode. The current (Data Ontap 8.1.1) Differences in functionality are as follows:

Cluster-mode only

Clustered scaleout (24-nas:4-san) (Multi-node cluster, up to 4 nodes in a cluster if SAN is provided)

Namespace (Unified namespace)

Nondisruptive Operations (smooth migration of volume or LUNs between nodes)

Management as single system (unified management of the entire cluster)

Scalable and integrated multi-tenancy (scalable and multi-tenancy)

NFS v4, v4.1 (PNFS); SMB 2.0, 2.1

Onboard Antivirus

7-mode only

SnapLock

SnapVault and OSSV

Qtree and Synchronous SnapMirror

Metrocluster

Vfiler

Flexshare

IPv6, HTTP, FTP, SFTP, TFTP

Both 7-mode and Cluster-mode

Unified Architecture

Storage efficiency features and (data deduplication and compression)

Snapshot copies and asynchronous volume SnapMirror

Intelligent Caching with Flash Cache
