vSAN File Services – How to find the connection URL
vSAN File Services adds a critical service to VMware Cloud Foundation. Layering a distributed protocol access layer on top of vSANs existing shared nothing distributed object store that can serve the NFS needs of Kubernetes as well as traditional services.
New shares setup in vSAN file services are balanced across the cluster. To find the IP address of which container you should connect to for a given share the interface offers this information for NFSv3.
Note NFSv4 is different. a NFSv4 referral enables a multi-server namespace to exist and seamlessly handle redirecting the client to the server that hosts a given directory or share. While it may appear as one namespace, All IO will not have to hairpin through the container owning the primary IP. Similar to iSCSI login Redirects, this simplifies setup, avoids the need for the client to attempt to connect to every node in the cluster.
What does this look like in the interface? This short 1 minute video may help:
VMware Cloud Foundation 4 is a powerful virtual machine and container platform. vSAN file services is critical to meeting the needs of modern applications and container workloads.
