What is High Performance Storage System? HPSS is software that manages
petabytes of data on disk and robotic tape libraries.
HPSS provides highly flexible and scalable hierarchical storage management
that keeps recently used data on disk and less recently used data on tape.
HPSS uses cluster, LAN and/or SAN technology to aggregate the capacity and performance
of many computers, disks, and tape drives into a single virtual file system
of exceptional size and versatility. This approach enables HPSS to easily meet
otherwise unachievable demands of total storage capacity, file sizes, data rates,
and number of objects stored. HPSS provides a variety of user and filesystem interfaces
ranging from the ubiquitous vfs, ftp, samba and nfs to higher performance pftp,
client API, local file mover and third party SAN (SAN3P). HPSS also provides hierarchical storage management (HSM) services for IBM General Parallel File System (GPFS).
Who developed HPSS? HPSS is the result of over a decade
of collaboration among five Department of Energy laboratories and IBM,
with significant contributions by universities and other laboratories worldwide.
Jointly developing open software with end users that have the most demanding
requirements and decades of high-end computing and storage system experience
has proven the recipe for continued innovation, industry leadership and leading
edge technology since 1992. The founding collaboration partners are
- IBM Global Services
- Lawrence Livermore National Laboratory
- Los Alamos National Laboratory
- National Energy Research Supercomputer Center (NERSC) at Lawrence Berkeley National Laboratory
- Oak Ridge National Laboratory
- Sandia National Laboratories
