High Availability Option for HPSS
IBM Global Services - Federal announces the High Availability option for HPSS. HA-HPSS* provides hardware redundancy for HPSS core servers, complementing the ability to configure redundancy in the data movers. The result is a mass storage system that remains on-line, in spite of failures in key hardware components.
High Availability Features: Components:
Minimize downtime
Automatically recover from:
  • Total failure of primary server computer
  • Power failure
  • Disk failure
  • Disk adapter failure
  • Network adapter failure and more...
  • Standard HPSS software
  • HACMP for AIX clustering software from IBM
  • Redhat Cluster Suite for Linux clustering software from Redhat
  • Redundant hardware components

Implementation Features
  • Two HPSS core server machines: one primary and one standby.
  • Primary computer services requests using "service interface."
  • Metadata is mirrored across busses.
  • "Keep alive" messages in AIX are exchanged between primary and standby over Ethernet and TTY cable (to prevent isolation).
  • "Keep alive" messages in Linux are exchanged between primary and standby over Ethernet and shared disk.
  • Network adapter failure causes a standby adapter to assume the IP and hardware address of the failed adapter.
  • Failures of disk, disk adapter, and cables are resolved by AIX mirroring over dual busses.
  • Primary computer failure results in the standby computer assuming the IP and hardware addresses of the service interface, taking control of the metadata disks, and restarting HPSS.

*HA-HPSS is available from IBM by special bid arrangements.

Swift On HPSS - Leverage OpenStack Swift to provide an object interface to data in HPSS. Directories of files and containers of objects can be accessed and shared across ALL interfaces with this OpenStack Swift Object Server implementation - Contact Us for more information, or Download Now.

Capacity Leader - ECMWF (European Center for Medium-Range Weather Forecasts) has a single HPSS namespace with 269 PB spanning 282 million files.

File-Count Leader - LLNL (Lawrence Livermore National Laboratory) has a single HPSS namespace with 64 PB spanning 966 million files.

RAIT - Oak Ridge National Laboratory cut redundant tape cost-estimates by 75% with 4+P HPSS RAIT (tape stripe with rotating parity) and enjoy large file tape transfers beyond 1 GB/s.
