Overview of Processors
Processors in a NonStop system are one of the following, which are described below:
• “Processors in NonStop Systems Running J-Series RVUs” (page 121)
• “NonStop NS16000 Series and NS14000 Series Blade Complex Processors” (page 122)
• “NonStop NS1200 and NS1000 Blade Element Processors” (page 124)
