How much do you really know about the networking capabilities built into NetApp ONTAP?
In this episode of the Tech ONTAP Podcast, NetApp networking expert Richard Scheffenegger joins us for a deep dive into the ONTAP networking stack—from foundational concepts such as VLANs and IPspaces to advanced topics including TCP optimization, failover groups, BGP, virtual IPs, and Anycast.
Richard explains how IPspaces can provide both security isolation and workload-specific network optimization, why different network conditions may require different TCP strategies, and how ONTAP networking has evolved to provide greater resiliency.
The discussion also explores BGP-based networking, including how dynamic routing can improve failover behavior and enable Anycast-style architectures.
Plus, Richard shares common ONTAP networking configuration mistakes—including why LACP IP-based hashing may not be the right choice for modern environments using nConnect and SMB Multichannel.
Topics include:
• VLANs and IPspaces
• Secure multi-tenancy
• TCP optimization
• SnapMirror networking
• TCP RACK
• Broadcast domains and failover groups
• LACP
• BGP and virtual IPs
• Anycast
• FlexCache
• ONTAP networking best practices
There was too much to cover in one episode, so stay tuned for future discussions on RDMA, AI/ML networking, and additional ONTAP network optimization techniques.
