First stock exchange in Russia called RTS was built originally on Stratus computers. First launch of the trades was done on Intel 960 based Stratus XA/R in 1995, then in late 1996 we migrated to two PA-RISC based Stratus Continuums, if memory servers me well. Both models provided quadruple redudancy and for the whole trades history we had no interruption related to hardware problems. Only bugs in our software. )) Continuums were working till 2003 when they were replaced with x86-based Stratus servers, which were double or triple redundant, depending on the model. They are still running at the RTS Exhange which is now part of Moscow Exchange (formely MICEX). The only problem with x86 models, at least the models produced back in mid-00 was that the backplane with synchroniztion clock was not redundant and if the clock failed the whole server went down.
