 HPSS for High Performance Storage System, is just what its name implies, i.e., a system capable of storing very large quantities of data with good performances during storage and recovery (write and read). However, if one does not respect certain conditions while using it, its performance is seriously degraded. HPSS for High Performance Storage System, is just what its name implies, i.e., a system capable of storing very large quantities of data with good performances during storage and recovery (write and read).

 +HPSS supports a maximum file size of 64 GB. __The optimal size is 4 GB.__
  
 The performance of HPSS is seriously degraded by the storage of small files, where "​small"​ generally indicates a file whose size in smaller than 100 MB. Nevertheless,​ the storage of smaller files is allowed in certain cases. If you need to store smaller files, contact us. Especially, one must never store files smaller than 20 MB without the carrying out of a preliminary study by the experiment and the Computing Center. The performance of HPSS is seriously degraded by the storage of small files, where "​small"​ generally indicates a file whose size in smaller than 100 MB.
