Scratch space is a disk at your disposition, that you can use to store whatever file you want. On scratch space, you can store any number of files of any dimension (compatibly with the overall disk space at disposition). No check will be performed to the files contained in this server, and no backup of these files will be performed either.

• No check means that you can store any kind of files, of whatever dimension and nobody will bother you about this.
• No backup means that no security system to recover your files will be performed apart from the existing Raid 5 configuration of the disks. This in order to maintain low the level of work needed for administration.
• The System Administrator does not loose time to check/verify/recover file stored in this disk space, don't ask.

To access the scratch files all you have to do is connecting to the directory scratch on server iscsrv14.epfl.ch by using Linux, Os X or Windows and you can use the disk space here for your needs. Recall that even others users needs to use the scratch space, so be gentle when you store your files.

Currently the scratch space has around 1 TByte (1000 GBytes) for storage. A large amount of space just for crap files that one want to access but that aren't vital.
