Non-Sensitive Data Storage

/home

/home is a free 50GB space provided to users of the Rivanna HPC system and is visible from the Rivanna login and compute nodes. /home is the default working directory when logging on to Rivanna. Users can also access their home directory at /home/$USER, where $USER is an individual’s UVa computing ID.

/scratch

/scratch is a Lustre high performance parallel filesystem accessible via the Rivanna login and compute nodes. All Rivanna HPC users are granted 10TB for free and can access this space within Rivanna at /scratch/$USER, where $USER is an individual’s UVa computing ID. The /scratch directory is not intended for long-term data storage. Files are flagged for removal 90 days after last modification timestamp.

#### 90 Day Deletion Users note that `/scratch` is designed for temporary storage for working jobs and should not be used as permanent storage. Files older than 90 days are deleted in a nightly process. [Read more](/userinfo/rivanna/storage/#scratch-cleanup-policy).

How to request /home and /scratch space

/home and /scratch space can be obtained by requesting an allocation on Rivanna. The process of getting access to Rivanna is described here.

/project

The /project file system provides users with a collaborative space for data storage and sharing. Members in the same group have access to a shared directory created by the team lead or PI. Group membership can be defined and managed through the ITS MyGroups system. /project storage is mounted on the Rivanna HPC cluster and runs on a new scale-out NAS file system.

How to request /project storage space

/project storage can be purchased for $60 /TB/YR by using this form. When filling out the form, the PI can specify the size of the /project directory and the name of an existing or new MyGroup that can access this space. We recommend choosing a MyGroup name specific to your group or collaboration for the /project directory. This will reduce confusion in the future if you manage multiple MyGroups and directories on other storage systems.

Once the request has been submitted, the PI will receive a notification that the /project space has been provisioned within 24 hours. Once the space becomes available, the PI can grant access to lab members by adding them to the MyGroup. Users in the MyGroup will see the directory (~/project/MyGroup_name) after logging into Rivanna. Addition and removal of users is managed by the PI of the group.

Data transfer

Non-Sensitive Storage Data Transfer

Non-Sensitive Data Transfer

#### Secure Copy (`scp`) `scp` uses secure shell (SSH) protocol to transfer files between your local machine and a remote host. scp can be used with the following syntax:

```scp [source] [destination]``` ```scp SourceFile mst3k@rivanna.hpc.virginia.edu:/scratch/mst3k``` ```scp SourceFile mst3k@rivanna.hpc.virginia.edu:/project/MyGroup_name``` Detailed instructions and examples for using `scp` are listed here.
#### Secure File Transfer Protocol (`sftp`) `sftp` is a network protocol for secure file management. Instructions and examples for using sftp are located here.
#### Filezilla & Cyberduck Filezilla and Cyberduck are open source FTP client software for file management through an interactive graphical user interface. Instructions for using these FTP clients can be found here.
#### Globus Connect (Large Data Transfer)

Globus provides access to data on local machines and Rivanna file systems, as well as external institutions and facilities. Globus is well suited for transferring both small files and large amounts of data. More information on Globus data transfer can be found here.

Non-sensitive Data Storage Systems

/home, /scratch, and /project storage are based on a Linux file system. Users can invoke generic Linux commands to manage files and directories (mv, cp, mkdir), manage permissions (chmod, chown) and navigate the file system (cd, ls, pwd). If you or your collaborators are unfamiliar with some of these commands, we encourage you to take time to review some of the material below:
