Clustered Data ONTAP 8.3 & MetroCluster

On October 28 at the NetApp Insight event in Las Vegas, NetApp announced new software, services, and partnerships that simplify data management across clouds. The announcement included a feature rich new version (8.3) of clustered Data ONTAP, Cloud ONTAP, OnCommand Cloud Manager and NetApp Private Storage for Cloud and a new service, Enterprise Transformation Workshop for Cloud.


Clustered Data ONTAP 8.3 enhances availability and performance for business-critical applications, simplifies upgrades, deployments and transitions, increases efficiency for entry systems, provides more granular data management for server virtualization, delivers greater SAN scaling and manageability, offers CIFS and NFS enhancements and improves performance of flash storage.


This blog is a first in a series that examine the key features of clustered Data ONTAP 8.3. One of the new features that enhance availability is MetroCluster, a no charge feature that provides continuous data availability for mission-critical applications in the event of a disaster.  MetroCluster software:


  • Protects against the major causes of downtime: power, cooling, and network faults, as well as disasters affecting your site.
  • Combines array-based clustering with synchronous mirroring to deliver continuous availability and zero data loss.mcc.png
  • Provides transparent recovery from failures.
  • Reduces administrative overhead and the risk of human error.
  • Needs only a single command for switchover.
  • Supports SAN and NAS environments.
  • Provides high availability and nondisruptive operations with a 2-node HA cluster at each site.
  • Offers a native feature with no license fee.


MetroCluster high-availability and disaster recovery software is used by thousands of enterprises and service providers worldwide for high availability, zero data loss, and nondisruptive operations both within and beyond the data center.

is there any change in metrocluster operation with previous ontap version , i could see the major benefit as license free ?



200km of wire is a lot of attack surface.  What's the encryption like between clusters?
