High Performance Storage System

HPSS Logo
Incremental Scalability
Based on storage needs and deployment schedules, HPSS scales incrementally by adding computer, network and storage resources. A single HPSS namespace can scale from petabytes of data to exabytes of data, from millions of files to billions of files, and from a few file-creates per second to thousands of file-creates per second.
About HPSS   :    HPSS Version 8.1.0

The following is an overview of three new features that can be found in HPSS 8.1.0.

New to HPSS 8.1.0

Ordered Migration by Directory

HPSS now supports the ability to co-locate data on tape by directory. The objective is to improve tape recall efficiency. This new feature is especially pertinent when considering the use of the Full Aggregate Recall (FAR) feature released in HPSS 7.5.3.

If users organize files by directory and usually recall files from a given directory in bulk, by using Ordered Migration by Directory and Full Aggregate Recall users may see a 7x to 10x improvement in recall performance. Thus, HPSS 8.1 may be able to meet site tape-recall requirements using many fewer tape drives when compared to HPSS 7.5.3.

The migration policy will continue to honor the migration policy settings for when a file is eligible for migration, how often migration will run and the number of migration streams to use.

Prevent tape-recall events from HPSS FUSE

The HPSS FUSE mount point may now be configured to deny users from triggering HPSS tape recall events. If the nostagetape HPSS FUSE mount point option is specified, no data is staged from tape-only files. If the stagetape HPSS FUSE mount point option is specified or not included, users will trigger HPSS tape recall events for files that are not on the HPSS disk cache.

Most UNIX commands that come from FUSE are blocked, so HPSS receives one tape-recall at a time. When HPSS receives one tape-recall at a time, HPSS does not have an opportunity to organize and optimize the tape recall events. On the other hand, if a site monitors log messages, triggers can be put in place to process the error messages that are logged when the nostagetape HPSS FUSE mount point option is specified, and a user tries to recall a file on tape. When files are recalled in bulk, HPSS will organize and optimize the tape-recall events.

HPSS accounting information by UID and GID

HPSS will now track accounting information by UID and GID rather than by Account ID alone.

Come meet with us!
2020 HUF - VIRTUAL
The 2020 HPSS User Forum (HUF) will be hosted virtually due to the COVID-19 pandemic. It will be hosted online for six days spread across three weeks in October 2020 with no admission cost. This will be a great opportunity to hear from HPSS users, collaboration developers, testers, support folks and leadership (from IBM and DOE Labs) - Learn More. Please contact us if you are not a customer but would like to attend.

HPSS @ MSST 2020 - POSTPONED
The 36th International Conference on Massive Storage Systems and Technology will be in Santa Clara, California sometime in October 2020. The increased-awareness of COVID-19 has caused the planners to slip the scheduled event from May 2020 to October 2020 - Learn More. Please contact us if you would like to meet with us in Santa Clara.

HPSS @ SC20
The 2020 international conference for high performance computing, networking, storage and analysis will be in Atlanta, Georgia from November 16th through 19th, 2020 - Learn More. Come visit the HPSS folks at the IBM booth and contact us if you would like to meet with the IBM business and technical leaders of HPSS in Atlanta.

HPSS @ STS 2021
The 3nd Annual Storage Technology Showcase is in the planning stage, but HPSS expects to support the event in March of 2021. Checkout their web site - Learn More. We expect an update later in 2020.

HPSS @ ISC21
The 2021 international conference for high performance computing, networking, and storage will be in Frankfurt, Germany from June 27st through July 1st, 2021 - Learn More. Come visit the HPSS folks at the IBM booth and contact us if you would like to schedule a face-to-face meeting with us in Frankfurt.

What's New?
HUF 2020 - The HPSS User Forum will be hosted virtually at no cost in October 2020.

HPSS 8.3 Release - HPSS 8.3 was released on March 31st, 2020 and introduces a new features.

HPSS 8.2 Release - HPSS 8.2 was released on December 6th, 2019 and introduces a few new features.

New Globus DSI - Version 2.9 of the HPSS DSI is now available from the GitHub release page. It provides the capability to resume interrupted Globus transfers.

Lots Of Data - In November 2019 IBM/HPSS delivered a system to a customer in Canada and demonstrated a sustained tape ingest rate of 11,574 MB/sec (1 PB/day peak tape ingest) while simultaneously demonstrating a sustained tape recall rate of 8,832 MB/sec (791 TB/day peak tape recall). HPSS pushed four 13-frame IBM TS4500 tape libraries (scheduled to house over 500 PB of tape media) to 2,168 mounts/hour.

HPSS 8.1 Release - HPSS 8.1 was released on October 1st, 2019 and introduces a few new features.

July 2019 - Argonne Team Breaks Record for Globus Data Movement from the Summit supercomputer at Oak Ridge National Laboratory to HPSS tape.

Capacity Leader - ECMWF (European Center for Medium-Range Weather Forecasts) has a single HPSS namespace with 479 PB spanning 331 million files.

File-Count Leader - LLNL (Lawrence Livermore National Laboratory) has a single HPSS namespace with 57 PB spanning 1.424 billion files.

Explosive data growth - HPSS Collaboration leadership from Lawrence Berkeley National Laboratory's National Energy Research Scientific Computing Center (NERSC) helped author the "NERSC Storage 2020" report, and NERSC trusts HPSS to meet their immediate and long term data storage challenges.
