Abstract
"..... In this activity, we present the results of our tests of two
leading file systems (GPFS and Lustre) on the same physical hardware.
This hardware is the standard commodity storage solution in use at
LLNL and, while much smaller in size, is intended to enable us to
learn about differences between the two systems in terms of
performance, ease of use and resilience. This work represents the
first hardware consistent study of the two leading file systems that
the authors are aware of."

この環境で
IOR (THROUGHPUT TESTING)

mdtest (METADATA PERFORMANCE TESTING, PER PROCESS METADATA SCALING STUDY)
http://sourceforge.net/projects/mdtest/
を使用して比較しています。
様々な条件で比較しているので、興味のある方はレポートに目を通して下さい。
※128ノード程度でサチるようなので、報告最大ノード数は 128です。
※この検証は DDN 9550 1台だけですが、実際には沢山のストレージがあります。
