Access to the storage is via your ULg's username and password.

Windows

• Click Map Network Drive in the menu bar at the top of the window
• Specify a Drive letter

- Example: \\storage.giga.priv\u123456

• Notch Connect using different credentials checkbox

• A window appears asking for your ULg username and password.
• Enter your ULG username after the word ULG\

- Example: ULG\u123456

• Enter your password and click OK
• You should be connected to your home storage

Mac OS

• In Finder, select Go > Connect to Server
• In the Server Address, enter cifs:// followed by the storage address and your ULg username

- Example: cifs://storage.giga.priv/u123456

• You will need to enter your ULg username and password
• You should be connected to your home storage

Linux

• Depending on the Linux distribution, the connection method may vary.

Accessibility of data

The data can be accessed from anywhere in the institution from the network (wired or wireless) of the ULG or CHU. To access data from the outside, you need to log to the ULg VPN.

To log in to the VPN, please visit https://www.ulg.ac.be/vpn. You should use the applications available at the bottom of the page.

Terms of Use

Quota

Each user has a personal space for storing their data. This space is currently limited to 100 GB per user. This quota can be reviewed at any time by the GIGA.

Inside each user storage space are also found links to group spaces : Administration (ADM), Platforms (PTF) and Research (URT).

These directories and their contents are subject to separated quotas, depending on the different entities. Heads of departments are responsible for defining these quotas and the use of their shared files. These folders are accessible from each user's personal space via shortcuts to the different entities.

Being in the user as well as the group space, they are all backuped every night between 0 a.m. and 6 a.m. meaning, in the cases listed under this paragraph, you might accidentally create huge amount of computing work for the backup system and that would result into an absence of it for at least one day.

Any action on data that weights a lot might need some special attentions and/or contacting support before doing it, like for example:

• Renaming folders and/or files
• Copy and/or move data
• Change ownership and/or rights
• Add data

In that perspective has been created a special condition : If you create, anywhere and as much as you want, a directory called nobackup, everything in it will not be backuped and so won't disturb the whole process.

Data

Raw data originating from scientific and/or cluster computer cannot be transferred and/or stored in the GIGA storage space as it. It must be the subject of prior consultation with the System manager for the implementation of a specific action.

It is mandatory to encapsulate and compress (ZIP, RAR, TAR...) this data in a file to facilitate their management and processing by the storage servers.

Any filename with non-UTF-8 characters (mostly for Windows users) or special characters such as /\:*?"'<>| will not be included in the backup.

It is prohibited to create files or folders in /gpfs0 nor in /gpfs0/home (Linked to /home/mass)

The users' home directory cannot be used as a temporary space for calculation or cluster document. The number of files generated during the calculations (sometimes tens of thousands) could completely block the storage space. There is a computing space on the Grid to do this.

The scratch space (SCR) is dedicated to the temporary space of calculation. This space will not be backup and if there is a problem of free space, it can be deleted of its contents to release space.
