Overview
Network File Storage uses the NFS protocol to provide shared data storage accessible to your VMs via a private network. It allows fine-grained POSIX permissions at file and directory levels. You can provision a shared Network File Storage using the NFS protocol. It enables easy data sharing between the connected VMs, all while benefiting from the reliability and security of a cloud-based storage solution.
During cluster creation, you must specify an IP address from your LAN for the cluster. The specified IP address is used as a floating IP address for the two VMs that the Network File Storage uses to provide high availability.
As seen in the illustration, you create a cluster within the Network File Storage and create shares within a cluster. Multiple VMs from within a VDC are connected to shares of a Network File Storage's cluster via a private LAN.
Each cluster can contain multiple shares within it. Shares are individual file systems within the storage. For example, you can imagine it as a cluster being a computer and shares are folders within it that are accessed by VMs. An administrator can allow VMs to use specific shares.
VMs on the same private network can connect to the Network File Storage's cluster. In addition, data can be accessed simultaneously from multiple compute instances (for example, VMs, and containers) without compromising data consistency. Multiple VMs from within the VDC can access the data simultaneously.
IONOS manages maintenance operations, such as software updates and hardware replacement, by offering redundant, high-availability cluster services.
You can also integrate it with Kubernetes clusters to provide persistent storage for containerized workloads.
