High Performance Storage System

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 Releases   :    New to HPSS Version 9.2.0

Improved Spectra Logic Terapacks support

HPSS groups tape moves belonging to the same Spectra Logic Terapack for improved mount and dismount performance.

Spectra Logic TAOS support

HPSS now supports the Spectra Logic Time-based Access Order System (TAOS) to improve the file-to-file seek time when recalling multiple files from an LTO tape cartridge. Details of the improved recall performance are found at the bottom of page 11 - up to a 4 times decrease in overall time needed to retrieve all of the files compared to random ordered recalls.

Increased the maximum individual disk size limit

The HPSS maximum individual disk size limit has been increased from 256 TB to 1 EiB.

Improved adler32 hash performance

HPSS is now compiled with zlib to support hardware acceleration for improved adler32 hash performance.

Support LTO-9

HPSS supports LTO-9 drives and media. The RAO (recommended access order) feature that is available on LTO-9 is also supported by HPSS.

Support for very large log messages

HPSS can potentially generate very large messages that can be truncated. Splitting log messages into multiple smaller messages prevents truncation. Split messages are logged with a “chunk number” so they can be stitched back together using the hpss_log_formatter tool.

Improved automatic small file tape aggregation performance

A tape drive’s native transfer rate can only be achieved when the tape drive is performing IO for 15 seconds or more. A 250 MB/s tape drive must do 4 GB of IO to achieve this native transfer rate. HPSS automatic small file aggregation is now based on the amount of data written to tape. Before HPSS 9.2 automatic small file aggregation was based on the number of files put into the aggregate, and that was capped at 1,000 files. The HPSS maximum number of small files that are automatically put into a tape aggregate has been increased from 1,000 files to 50,000 files. To further improve automatic small file aggregation performance, HPSS has improved end-of-media (EOM) handling when writing small file tape aggregates. A further benefit of this improved EOM handling is an increase in tape cartridge space utilization.

Improved small file tape aggregate support with HPSS repack tool

HPSS repack tool also had the same 1,000 file limit before HPSS 9.2. Similar small file tape aggregation improvements (as stated above) were made to the HPSS repack tool.

User Defined Attributes (UDA) support via PFTP

PFTP now supports getting and setting UDAs.

Come meet with us!
COVID-19 has disrupted the 2021 HPSS User Forum (HUF) and the Karlsruhe Institute of Technology (KIT) in Karlsruhe, Germany is no longer hosting the event. The 2021 HUF will be hosted online for six days spread across three weeks in October 2021 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.

The 2021 international conference for high performance computing, networking, storage and analysis will be in St. Louis, MO from November 15th through 18th, 2021 - Learn More. As we do each year, we are scheduling and meeting with customers via IBM Single Client Briefings. Please contact your local IBM client executive or contact us to schedule a HPSS Single Client Briefing to meet with the IBM business and technical leaders of HPSS.

HPSS @ STS 2022
The 4th Annual Storage Technology Showcase is in the planning stage, but HPSS expects to support the event in March of 2022. Check out their web site - Learn More. We expect an update in early fall 2021.

HPSS @ MSST 2022
The 37th International Conference on Massive Storage Systems and Technology will be in Santa Clara, California in May of 2022 - Learn More. Please contact us if you would like to meet with the IBM business and technical leaders of HPSS at Santa Clara University.
