re: http://www.garlic.com/~lynn/2012l.html#16 X86 server http://www.garlic.com/~lynn/2012l.html#18 X86 server in ha/cmp we spent some amount of time with siac ... ran dataprocessing for exchange ... they had a carefully selected datacenter in a building that had lots of diverse routing ... two different water mains on different sides of the building, different electrical mains on different sides of the building to different substations, and four different telco feeds on four sides of the building into four different central exchanges (this besides UPS and power backup). past posts mentioning ha/cmp http://www.garlic.com/~lynn/subtopic.html#hacmp one of their outages was when the transformers in the basement blew-up contaminanting the building with PCB ... and the building had to be evacuated. misc. past posts mentioning SIAC http://www.garlic.com/~lynn/2005i.html#0 More Phishing scams, still no SSL being used http://www.garlic.com/~lynn/2007e.html#16 Attractive Alternatives to Mainframes http://www.garlic.com/~lynn/2007k.html#41 DEC and news groups http://www.garlic.com/~lynn/2007n.html#31 IBM obsoleting mainframe hardware http://www.garlic.com/~lynn/2008b.html#36 windows time service http://www.garlic.com/~lynn/2009g.html#2 Just posted third article about toxic assets in a series on the current financial crisis http://www.garlic.com/~lynn/2009i.html#23 Why are z/OS people reluctant to use z/OS UNIX?
