The Intel January 2014 white paper "Architecting a high performance storage system" serves as a good starting point for optimizing Lustre SFF.
Backend Storage
smartctl
smartctl (smartmontools; Self-Monitoring, Analysis and Reporting Technology System) is used to uniquely identify devices, conduct device testing, and assess the health of devices.
sgpdd_survey
sgpdd_survey (sg3_utils) is used to analyze backend storage (dd is not suitable as response to multiple IO threads is of interest).
