Scalable Capacity
As architects continue to exploit hierarchical storage systems to scale critical data stores beyond a petabyte (1015 bytes) towards an exabyte (1000 petabytes), there is a equally critical need to deploy a high performance, reliable and scalable HSM.

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.

What do HPSS users store?

HPSS provides storage management for a diverse set of digital library, science, engineering and defense applications and safeguards a range of data including nanotechnology, genomics...

Who has a petabyte or more?

These HPSS Collaboration Members' sites have accumulated a petabyte or more of data, in a single HPSS file system. Some have passed fifteen petabytes, heading for twenty.
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.

NCSA in production with RAIT - A massive 380 petabyte HPSS system was successfully deployed. -- the world’s largest automated near-line data repository for open science. Learn more from NCSA, and HPCwire. The new HPSS system went into production using HPSS Redundant Array of Independent Tapes (RAIT) tiers, which is similar to RAID, providing redundancy for a tape stripe. RAIT allows HPSS customers to meet their performance and redundancy requirements without doubling their tape cost. Learn more about RAIT.
