NetApp – Configuring the Two Node Cluster – Part 6
This article will demonstrates that how to configure the NetApp (Clustered ONTAP) two node cluster. Since I am going to use the simulator for this demonstration, we can’t virtualize the HA pair controllers. I will use two separate nodes to form the cluster with switch-less configuration(Assuming that direct cluster inter-connect cabling is done between nodes). […]
NetApp – Clustered DATA ONTAP – Write Operations – Part 5
This article is going to explain about the Netapp write operations. In Clustered Data ONTAP , write request might land on any of the cluster node irrespective of the storage owners. So that data write operations will be either direct access or indirect access. The Write requests will not send to the disks immediately until CP […]
