Use this worksheet to calculate the amount of storage space required for the system storage pool.

Fileset measurements

  Fileset 1 Fileset 2 Fileset 3 Total
Total data size (byte)        
Number of files        
Number of directories        
Number of symbolic links        
Number of hard links        
Number of FIFO objects        
Average object-name length        

File-metadata storage space

Total data size * 415 / 1 000           bytes
Total number of files * ( 560 + ( 3 * name length ) )           bytes
Total number of directories * ( 560 + ( 3 * name length ) )           bytes
Total number of symbolic links * ( 560 + (3 * name length ) )           bytes
Total number of hard links * ( 90 + ( 3 * name length ) )           bytes
Total number of FIFO objects * ( 560 + ( 3 * name length ) )           bytes
Total / 1 000 000           MB

System-metadata storage space

Number of metadata servers * 128 MB           MB

Total storage space required

File-metadata storage + system metadata storage           MB
