Symmetric multiprocessing vendor Advanced Logic Research (ALR) has added fault tolerant features to its range of Pentium Pro multiprocessor servers. These are OEMd by both Data General and Unisys as part of their PC ranges.
Active central processor recovery (ACPR) will let individual Intel chips in servers go belly-up, recover from dangerous software scenarios, and reboot systems to prevent network failures, if these eventualities happen.
Data General and Unisys servers are likely to use the ALR Informanager hardware and software solution for servers, according to a source at the company in Irvine, California. The software will tell network managers about heat problems, voltage fluctuations, whether server doors are open or closed, how fans are performing, and other PC interfaces, she said.
The user-selectable features will give auto-reconfiguration to the OEMd machines, meaning that chips that deliver any problems to the software will down themselves and put another chip into operation.
