Clustered Data ONTAP (C-Mode) is a highly scalable storage operating system that allows multiple NetApp storage controllers to be combined into a single integrated system for horizontal scalability and non-disruptive operations across the hardware lifecycle. It also delivers improved performance, management simplicity, and reliability.

These are some of the key features of Clustered Data ONTAP:

  • Support for up to 24 nodes in a single system
  • Flexible cluster configurations that combine heterogeneous controllers
  • Transparent data movement between nodes (DataMotion for Volumes)
  • Single namespace or multiple namespaces
  • Non-disruptive operations for storage maintenance, hardware lifecycle operations, and software upgrades, including full technical refresh
  • Native multi-tenancy with quality of service (QoS) workload management
  • Support for SAN and NAS protocols (FC, FCoE, iSCSI, NFS, CIFS/SMB)
  •  Full support for Virtual Storage Tier, including Flash Cache, Flash Pool, and Flash Accel software

These capabilities are achieved by using network access protocols such as Network File System (NFS), Common Internet File System (CIFS), HTTP, FTP, Network Data Management Protocol (NDMP), as well as storage area network technologies such as iSCSI, Fibre Channel over Ethernet (FCoE), and Fibre Channel Protocol (FCP).
