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:|
Automatically recover from:
- 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.
2012 HPSS Users Forum - The 2012 HPSS Users Forum (HUF) will be hosted by CEA and held at the Hotel Pullman (Paris Bercy) in Paris, France. The conference will run October 15th through noon on October 18th. The conference website is now available http://www-hpc.cea.fr/en/HUF2012/index.htm for users to register, view the draft agenda, and obtain other related information about the meeting. The length of the conference is the same as last year - 3 1/2 days, with time available in the evening to visit/tour Paris.
|Purdue University: Data Storage Archive- Information Technology at Purdue will be upgrading the Fortress archive system from EMC's DiskXtender (DXUL) to IBM's High Performance Storage System (HPSS). In addition to the new archive data, HPSS will manage and retrieve the legacy data on DXUL tapes. For more details, please visit http://www.rcac.purdue.edu/news/detail.cfm?NewsID=475|
|Library of Congress: Data Storage Archive - The Library of Congress has acquired HPSS for use in the National Audiovisual Conservation Center. The NAVCC is located in Washington, DC and at the Packard Campus for Audio-Visual Conservation, located in Virginia.|
