 ## Large Files in /scratch
 
-The data containers in Lustre are called object storage targets (OST).  The capacity of one OST is
-about 21 TB. All files are striped over a certain number of these OSTs. For small and medium files,
-the default number is 2. As soon as a file grows above \~1 TB it makes sense to spread it over a
-higher number of OSTs, eg. 16. Once the file system is used \> 75%, the average space per OST is
-only 5 GB. So, it is essential to split your larger files so that the chunks can be saved!
