Differences between Netapp 7 Mode and Netapp Cluster Mode:
The Netapp cluster mode is an upgrade or an upgraded version of Netapp 7 Mode
There are some major differences between clustered Data ONTAP configurations and the configurations, operating with Data ONTAP in 7-Mode. In the clustered data ONTAP, the cluster configuration contains two HA pairs, with each HA in a separate cluster and at physically different sites.
While, the number of storage controllers is 4 in clustered mode, there are two storage controllers in 7 Mode. In case of the clustered configuration, the controllers are configured as two different HA pairs, with one on each site. In case of the 7 Mode, two controllers are configured as a single HA pair, with one controller at each site.
A local failover is available in the clustered mode, but is not available in 7- Mode. In case of the clustered mode, a failover can happen at either site and without causing the overall switch-over of the complete configuration. In case of the 7-Mode, whenever a problem occurs at one of the site, the system gets fail over to the partner site also.
In both the cases of Netapp 7 Mode as well as Netapp cluster mode, there is a single command for failover or switch-over. The cluster configuration does not support the DS 14 disk shelves and on the other hand, the 7-Mode configuration supports the DS 14 disk shelves. In both the cases of clustered mode and 7-Mode configurations, there is the use of two FC switch fabrics.
Besides the above differences, there are other differences b/w 7Mode and Netapp Cluster Mode
1) In the 7 mode, the configuration supports only 2 nodes and in case of cluster mode, it supports about 24 nodes.
2) In case of 7 mode Netapp configuration, it supports flat command line interface, whereas in case of clustered Netapp mode, it supports the hierarchal command line interface.
3) Vserver, in case of the clustered mode, is defined as a logical container, which can hold the volumes. The Vfiler in case of 7 Mode is a Vserver, in case of the clustered mode configurations.
4) The concept of junction path is a new concept in the case of cluster mode and is used for mounting purposes.
5) In case of the Cluster Mode configuration, the volume cannot be exported and the share cannot be created, until the volume is mounted to the junction point in a name space.
Thus, we have seen that the Netapp Cluster Mode is an upgraded version of Netapp 7 Mode, with some key differences. The Netapp Cluster Mode is also known as Netapp Cmode.
