About once a year, the Lustre Engineering team gathers to discuss new features under development and testing efforts. In November 2009, the senior Lustre engineers met in conjunction with the SC'09 event in Portland, Oregon, to discuss designs for upcoming features and implementation status of current development projects.

The DARPA High Productivity Computing Systems (HPCS) project is a program created to ensure that US Government agencies continue to have access to the advanced high-performance computing technologies needed to fulfill their missions. The program objectives include achieving extremely high IO performance and file system scale and reliability. Cray Inc. has partnered with Sun to use Lustre to achieve these goals.

The Lustre team has prepared several design documents as part of the HPCS program. These designs are:

   * Lustre HPCS Design Overview
   * Filesystem Integrity Check Design
   * End to End Data Integrity Design
   * LNet Channel Bonding Design
   * Rebuild Performance Design
   * Clustered Metadata Design
