Clustered Data ONTAP 8.3 – DataMotion for LUNs (SAN) and Automated NDU

My prior two blogs focused on some of the key new features (MetroCluster, SnapMirror, SnapVault) of clustered Data ONTAP 8.3 that enhance nondisruptive operations and data availability. There are three more features, DataMotion for LUNs, automated NDU, and SMTape in the payload that also provide enhancements to nondisruptive operations.

DataMotion for volumes has always been supported in clustered Data ONTAP.  What’s new is added granularity for LUN data mobility.  It provides near-instantaneous LUN mobility to resolve performance and capacity issues without affecting running applications.  You can manage performance and capacity for business-critical SAN workloads with no downtime and enable performance tiering as required with appropriate SSD/SAS/SATA storage.

 

With clustered Data ONTAP we have always been able to do a nondisruptive upgrade (NDU) from one version of the operating system to another.  For example, from version 8.1 to 8.2 or from 8.2 to 8.2.2.  However, many of the steps to do the upgrade were manual. Now starting with version 8.3 the process is automated providing the following benefits: Frees up time to focus on more strategic projects, reduces the likelihood of human error and reduces the manual steps needed to upgrade the operating system.

 

SMTape simplifies and speeds backup to tape.

 

To summarize, with clustered Data ONTAP 8.3, NetApp continues to set the standard for nondisruptive operations and availability features. The release provides:

  • Continuous availability and zero data loss in the event of a disaster
  • Faster and more flexible data replication, backups, and restores
  • Granular data mobility for SAN environments to balance capacity and performance

Stay tuned for my next blog on the new efficiency features with clustered Data ONTAP 8.3.
