Oracle Cloud Infrastructure File Storage service (FSS) is a fully-managed file storage service to provide full elasticity and scalability. FSS supports Network File System (NFS) protocol version 3 along with Network Lock Manager (NLM). FSS is an enterprise-grade file service that scales up to meet your storage needs and is accessible concurrently by thousands of compute instances. You can start with a file system that contains only a few kilobytes (KB) of data and scale to 8 exabytes (EB) of data without any up-front capacity planning or provisioning. Moreover, your data and metadata are protected with encryption at rest, and by snapshot capabilities that allow you to create up to 10,000 read-only snapshots per file system.
You should use File Storage when:
File Storage service provides you with various data management options, operational flexibility, and pay-per-capacity pricing .
File Storage service supports a broad range of use cases, including:
Any application that uses NFS v.3 works with minimal to no modification with FSS. This includes Oracle applications and solutions such as Oracle E-Business Suite, and transactional workloads such as Oracle Database and MySQL.
By default, File Storage allows you to create 100 file systems and 2 mount targets in every availability domain of your choice. Each file system can grow to 8 exabytes of data. You can create 10,000 snapshots of every file system. Visit Service Limits for a list of default settings and instructions for requesting an increase.
File Storage service supports NFS v.3, including a file locking mechanism that uses Network Lock Manager (NLM) protocol. FSS works with common NFS v.3 clients, including those on Linux, Solaris, and Windows, as well as Oracle's Direct NFS driver. Please refer to the FSS User Guide on how to mount from Unix-style and Windows systems.
Your data is replicated for durability within each availability domain, in a highly-available infrastructure that implements industry-leading data protection techniques and best practices. The File Storage service is designed to provide 99.999999999% (Eleven 9’s) annual durability for file systems. However, we recommend that you make regular backups to protect against the failure of an availability domain.
File Storage service lets you create snapshots using the web-based Console , command line interface (CLI) , REST APIs , or from the file system itself by creating a directory in the file system's .snapshot directory. Snapshots provide a read-only, space-efficient, point-in-time view of your entire file system. File Storage snapshots employ copy-on-write and consume storage space only when data changes. You'll only be billed for the storage space that your snapshots use for the delta of your changed data.
For an overview of File Storage service and it concepts, visit the FSS User Guide . You can create a file system and mount to it with only few clicks in the web-based Console. Moreover, you can also use the REST APIs , CLI and Terraform to create file systems and mount targets.
After creating a file system and a mount target, access your file system from compute instances . Log into your compute instance to install the NFS client and mount to your mount target . For information on installing the NFS client, please refer to the mounting instructions for each instance type:
File Storage is physically located in every Oracle Cloud Infrastructure availability domain—you can access it from anywhere! To access it within a region, you need only to ensure that your security rules are correctly configured to allow NFS traffic. For more information, see Configuring VCN Security List Rules for File Storage. For on-premises connection to your file system, you also need FastConnect or a virtual private network (VPN). Accessing a file system from an instance in a different Oracle Cloud Infrastructure availability domain incurs a small performance penalty because of the network latency that exists between availability domains.
For information about removing locks from a file system, see the user guide .
Use rsync, tar, or any third-party tool that supports NFS v.3 to copy your data to another Oracle Cloud Infrastructure availability domain, region, Oracle Object Storage , or your on-premises storage.
You can use standard tools like scp, rsync, or SSHFS to move data. Because File Storage service can be accessed from multiple Oracle Compute instances concurrently, you can improve copying speeds with parallel uploads. If you want to bring data from outside of a region, use VPN or a FastConnect connection to mount to your File Storage service from your on-premises data center.
Yes, you can use NFS export options on export paths for achieving that. Export paths are specified when a file system is associated with a mount target. The export path uniquely identifies the file system within the mount target, letting you associate up to 100 file systems behind a single mount target. The export path is appended to the mount target IP address, and used to mount (logically attach) to the file system. The export path exists solely as a way to distinguish one file system from another within a single mount target. For more information, visit Paths in File Systems . After creating a file system, you must set security options on your export paths for granular access control to limit root user access, require connection from a privileged port, or completely deny access to some clients. For more information on access control lists with NFS export options, visit Working with NFS Export Options .
File Storage service provides several methods of ensuring that your data remains secure. Use these methods in concert to restrict access to your file systems:
See About Security in the documentation for more information about how different types of security work together in your file system.
File Storage service uses strong encryption, with unique keys for each file system. Encrypted data includes all file data, file names, and directory names.
To optimize the performance of File Storage, consider the following guidelines:
