How to see data transfer on an ONTAP cluster network
ONTAP clusters utilize a backend cluster network to allow multiple HA pairs to communicate and provide more scale for performance and capacity. This is done by allowing you to nondisruptively add new nodes (and, as a result, capacity and compute) into a cluster. Data will be accessible regardless of where you connect in the cluster. … Continue reading How to see data transfer on an ONTAP cluster network

How to Map File and Folder Locations to NetApp ONTAP FlexGroup Member Volumes with XCP
The concept behind a NetApp FlexGroup volume is that ONTAP presents a single large namespace for NAS data, while ONTAP handles the balance and placement of files and folders to the underlying FlexVol member volumes, rather than a storage administrator needing to manage that. I cover it in more detail in: TR-4571: NetApp FlexGroup Volumes … Continue reading How to Map File and Folder Locations to NetApp ONTAP FlexGroup Member Volumes with XCP
How to identify a file or folder in ONTAP in NFS packet traces
When you're troubleshooting NFS issues, sometimes you have to collect a packet capture to see what's going on. But the issue is, packet captures don't really tell you the file or folder names. I like to use Wireshark for Mac and Windows, and regular old tcpdump for Linux. For ONTAP, you can run packet captures … Continue reading How to identify a file or folder in ONTAP in NFS packet traces
MacOS NFS Clients with ONTAP – Tips and Considerations
When I'm testing stuff out for customer deployments that I don't work with a ton, I like to keep notes on the work so I can reference it later for TRs or other things. A blog is a great place to do that, as it might help other people in similar scenarios. This won't be … Continue reading MacOS NFS Clients with ONTAP – Tips and Considerations
How to Configure MacOS to Use Active Directory LDAP for UNIX users/groups
In NetApp ONTAP, it's possible to serve data to NAS clients over SMB and NFS, including the same datasets. This is known as "multiprotocol NAS" and I cover the best practices for that in the new TR-4887: TR-4887: Multiprotocol NAS Best Practices in ONTAP When you do multiprotocol NAS in ONTAP (or really, and storage … Continue reading How to Configure MacOS to Use Active Directory LDAP for UNIX users/groups
