The HPSS Collaboration between IBM Houston Global Services and what are now five DOE National Laboratories (Lawrence Berkeley, Lawrence Livermore, Los Alamos, Oak Ridge, and Sandia) began in the fall of 1992. The goal was to produce a highly scalable high performance storage system. The High Performance Storage System (HPSS) needed to provide scalable hierarchical storage management (HSM), archive, and file system services. No product meeting the requirements existed. When HPSS design and implementation began scientific computing power and storage capabilities at a site, such as a DOE national laboratory, was measured in a few 10s of gigaops, data archived in HSMs in a few 10s of terabytes at most, data throughput rates to an HSM in a few megabytes/s, and daily throughput with the HSM in a few gigabytes/day. At that time, the DOE national laboratory and IBM HPSS design team recognized that we were headed for a data storage explosion driven by computing power rising to teraops/petaops requiring data stored in HSMs to rise to petabytes and beyond, data transfer rates with the HSM to rise to gigabytes/s and higher, and daily throughput with a HSM in 10s of terabytes/day. Therefore, we set out to design and deploy a system that would scale by a factor of 1,000 or more and evolve from the base above toward these expected targets and beyond.
Because of the highly scalable HPSS architecture these targets have been successfully met. We now recognize that computing power will rise to exaops by about 2020 with a corresponding rise in the need to scale storage in its various dimensions by another factor of 1,000. Further, other major application domains, such as real-time data collection, also require such extreme scale storage. We believe the HPSS architecture and basic implementation, built around a scalable relational database management system (IBM’s DB2) make it well suited to this challenge.
For a distributed collaboration such as the HPSS Collaboration that is producing a major software system to be successful careful thought went into its basic organization. Its basic governing document is a Collaboration Agreement spelling out intellectual property rights of the development partners and their management and organization. IBM has the responsibilities for commercialization and deployment, outside the development partners. There is an Executive Committee co-chaired by IBM and DOE lab representatives that sets major development and other policies. This group meets several times a year, primarily by teleconference. HPSS development is overseen by a Technical Committee coordinated by an IBM project manager. This group is generally organized around the major architectural modules of the system. It meets weekly, and more often as needed, by teleconference and once or twice a year in person. Development of the system follows industry standard software engineering practices and has an SEI CMM Level 3 rating. Following these software engineering practices has been a major factor in its success in producing a stable maintainable product.
The HPSS collaboration is based on the premise that no single organization has the experience and resources to meet all the challenges represented by the growing imbalance between computing power and data collection capabilities, and storage system I/O, capacity, and functionality. Over 20 organizations including industry, Department of Energy (DOE), other federal laboratories, universities, National Science Foundation (NSF) supercomputer centers and French Commissariat a l'Energie Atomique (CEA) have contributed to various aspects of this effort.
The primary HPSS development team consists of
- IBM Global Business Services (Houston, TX)
- Los Alamos National Laboratory (Los Alamos, NM)
- Lawrence Livermore National Laboratory (Livermore, CA)
- Lawrence Berkeley National Energy Research Supercomputer Center (Berkeley, CA)
- Oak Ridge National Laboratory (Oak Ridge, TN)
- Sandia National Laboratory (Albuquerque, NM)
- Commissariat a l'Energie Atomique, Direction des Applications Militaires (Bruyeres le Chatel, France)
- Gleicher Enterprises (Tucson, AZ)
2012 HPSS Users Forum - The 2012 HPSS Users Forum (HUF) will be hosted by CEA and held at the Hotel Pullman (Paris Bercy) in Paris, France. The conference will run October 15th through noon on October 18th. The conference website is now available http://www-hpc.cea.fr/en/HUF2012/index.htm for users to register, view the draft agenda, and obtain other related information about the meeting. The length of the conference is the same as last year - 3 1/2 days, with time available in the evening to visit/tour Paris.
|Purdue University: Data Storage Archive- Information Technology at Purdue will be upgrading the Fortress archive system from EMC's DiskXtender (DXUL) to IBM's High Performance Storage System (HPSS). In addition to the new archive data, HPSS will manage and retrieve the legacy data on DXUL tapes. For more details, please visit http://www.rcac.purdue.edu/news/detail.cfm?NewsID=475|
|Library of Congress: Data Storage Archive - The Library of Congress has acquired HPSS for use in the National Audiovisual Conservation Center. The NAVCC is located in Washington, DC and at the Packard Campus for Audio-Visual Conservation, located in Virginia.|
