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.

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.

HPSS VFS for RHEL 6 is available - HPSS Virtual File System (VFS) allows a computer to use the UNIX mount command to mount the HPSS name space, much like NFS is mounted. Learn more about VFS.
