You can connect to a File Storage service file system from any bare metal,&nbsp;virtual machine, or container instance in your Virtual Cloud Network (VCN). You can also&nbsp;access a file system from outside the VCN using Oracle Cloud Infrastructure FastConnect and Internet Protocol security (IPSec) virtual private network (VPN). The File Storage service&nbsp;supports the Network File System version 3.0 (NFSv3) protocol. The service supports the&nbsp;Network Lock Manager (NLM) protocol for file locking functionality.&#8221;<\/p>\n<p><strong>&nbsp;Key characteristics of OCI FSS:<\/strong><br \/>\nAccording to the <a href=\"https:\/\/questoraclecommunity.org\/learn\/blogs\/case-study-using-oci-file-storage-service-fss-for-peoplesoft\/\">Case Study: Using OCI File Storage Service (FSS) for PeopleSoft<\/a>&nbsp;OCI FSS characteristics include the following:<\/p>\n<ul>\n<li>NFS v.3 with NLM for POXIS<\/li>\n<li>AD-local service available in all OCI regions<\/li>\n<li>Predictable pricing for capacity stored<\/li>\n<li>Elastic performance where throughput grows with the capacity stored, is best suited for parallel workloads<\/li>\n<\/ul>\n<p><strong>Use cases for OCI FSS include:&nbsp;<\/strong><\/p>\n<p>The case study: Using <a href=\"https:\/\/questoraclecommunity.org\/learn\/blogs\/case-study-using-oci-file-storage-service-fss-for-peoplesoft\/\">OCI File Storage Service (FSS) for PeopleSoft<\/a>&nbsp;mentions the following use cases:<\/p>\n<ul>\n<li>On-demand scaling for shared access and capacity<\/li>\n<li>Lift-and-shift applications<\/li>\n<li>Backup in the cloud<\/li>\n<li>Storing structured or unstructured data for big data and analytics<\/li>\n<li>Testing and development<\/li>\n<li>Big Data and analytics<\/li>\n<li>High-Performance Computing (HPC)<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/blog_article_images\/26511-body-Picture3_16.png\" alt=\"OCI multitenant pic 3\" \/><\/p>\n<p><a href=\"https:\/\/www.youtube.com\/watch?v=XXqTGF8G0dk\"><em>Image Source<\/em><\/a>&nbsp;<\/p>\n<p><strong>How to create FSS in OCI<\/strong><\/p>\n<p>Before discussing the details of creating FSS in OCI, you need to understand some important concepts to use during FFS creation.&nbsp;<\/p>\n<p>The following subsections come directly from&nbsp;<a href=\"https:\/\/docs.cloud.oracle.com\/en-us\/iaas\/Content\/File\/Concepts\/filestorageoverview.htm\">Oracle Cloud Infrastructure Documentation<\/a><\/p>\n<p><strong>VIRTUAL CLOUD NETWORK (VCN)<\/strong><\/p>\n<p>&#8220;A private network that you set up in the Oracle data centers, with firewall rules and specific types of communication gateways that you can choose to use.&#8221;<\/p>\n<p><strong>SUBNETS<\/strong><\/p>\n<p>&#8220;Subdivisions you define in a VCN (for example, 10.0.0.0\/24 and 10.0.1.0\/24). Subnets&nbsp;contain virtual network interface cards (VNICs), which attach to instances. A subnet can&nbsp;span a region or exist in a single availability domain. A subnet consists of a contiguous&nbsp;range of IP addresses that do not overlap with other subnets in the VCN. For each subnet,&nbsp;you specify the routing rules and security lists that apply to it.&#8221;<br \/>\n&nbsp;<\/p>\n<p><strong>SECURITY RULES<\/strong><\/p>\n<p>&#8220;Virtual firewall rules for your VCN. Your VCN comes with a default security list, and you&nbsp;can add more. These security lists provide ingress and egress rules that specify the types&nbsp;of traffic allowed in and out of the instances. You can choose whether a given rule is&nbsp;stateful or stateless. Security list rules must be set up so that clients can connect to&nbsp;file system mount targets.&#8221;<\/p>\n<p><strong>Mount Target<\/strong><\/p>\n<p>&#8220;A mount target is an NFS endpoint that lives in a VCN subnet of your choice and provides network access for file systems. The mount target provides the IP address or DNS name that&nbsp;is used together with a unique export path to mount the file system.&#8221; A single mount target&nbsp;can export many file systems.<\/p>\n<p><strong>EXPORT<\/strong><\/p>\n<p>&#8220;Exports control how NFS clients access file systems when they connect to a mount target.&nbsp;File systems are exported (made available) through mount targets. Each mount target maintains&nbsp;an export set that contains one or many exports. A file system must have at least one export&nbsp;in one mount target&#8221; for instances to mount the file system.<\/p>\n<p><strong>EXPORT SET<\/strong><\/p>\n<p>&#8220;Collection of one or more exports that control what file systems the mount target exports&nbsp;using NFSv3 protocol and how those file systems are found using the NFS mount protocol.&nbsp;Each mount target has an export set. Each file system associated with the mount target has&nbsp;at least one export in the export set.&#8221;<\/p>\n<p><strong>EXPORT PATH<\/strong><\/p>\n<p>&#8220;A path that is specified when an export is created. It uniquely identifies the file system&nbsp;within the mount target, letting you associate up to one hundred file systems to a single&nbsp;mount target. This path is unrelated to any path within the file system itself, or the&nbsp;client mount point path.&#8221;<\/p>\n<p><strong>Setup overview<\/strong><\/p>\n<p>You need to create a setup, as shown in the following image. You need to create one virtual&nbsp;cloud network (VCN) in one AD and two subnets (public and private) under one VCN. You use&nbsp;a private subnet for a mount target and a public subnet for an NFS client. Each subnet has&nbsp;its own security rules and routing tables to allow the traffic in and out.<\/p>\n<p><img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/blog_article_images\/26511-body-Picture4_10.png\" alt=\"OCI multitenant pic 4\" \/><\/p>\n<p><a href=\"https:\/\/www.youtube.com\/watch?v=F5Umaxw6IL8&amp;t=319s\"><em>Image Source<\/em><\/a>&nbsp;<\/p>\n<p><strong>Steps to create FSS in OCI<\/strong><\/p>\n<p><strong>1.
