General
The High Performance Storage System (HPSS) is developed by a collaboration consisting of several labs in the US and led by IBM. HPSS is a Hierarchical Storage Management System (HSM) and it is designed to manage petabytes of data stored on disks and in tape libraries. More information on the system can be found here: http://www.hpss-collaboration.org/
Currently HPSS at HLRS manages 500 TB of disk storage and more than 4PB tape storage held in two copies.
Hardware
In the HPSS complex, 19 x86 servers are building a distributed system consisting of a core server, disk as well as tape movers. Each system is equipped with 32 cores on 2 sockets using 32 GB (movers) or 128GB (core server) of main memory.
Metadata is redundantly held on IBM v3700 Storwize device.
As disk cache, 4 SNA460 are used controlling 500TB disk space.
The tapes are stored in two spatially separated copies on IBM TS3500 Tape libraries with approx. 4000 tapes. The first copy is stored on EO7 Jaguar media whereas the second copy is stored on LTO6 media technology.
Software
We are currently using HPSS version 7.4.2 distributed by IBM. HPSS is a Hierarchical Storage Management System (HSM) which is able to manage petabytes of data on disk and tape storage and is used by the big HPC sites across the world.
