There is default stripe configuration for Salomon Lustre file systems. However, users can set the following stripe parameters for their own directories or files to get optimum I/O performance:
1. stripe_size: the size of the chunk in bytes; specify with k, m, or g to use units of KB, MB, or GB, respectively; the size must be an even multiple of 65,536 bytes; default is 1MB for all Salomon Lustre file systems
1. stripe_count the number of OSTs to stripe across; default is 1 for Salomon Lustre file systems one can specify -1 to use all OSTs in the file system.
1. stripe_offset The index of the OST where the first stripe is to be placed; default is -1 which results in random selection; using a non-default value is NOT recommended.

!!! note
Setting stripe size and stripe count correctly for your needs may significantly impact the I/O performance you experience.
