Why Do Mainframes Still Exist? What’s Inside One? 40TB, 200+ Cores, AI, and more!

Dave explores the IBM z16 mainframe from design to assembly and testing. What’s inside a modern IBM z16 mainframe that makes it relevant today? For info on my book on ASD/Asperger’s, please check out: 0:00 Introduction 4:47 Inside the z16 7:03 Super Input Output 9:39 Factory Assembly 10:56 Accelerators 12:24 Test Lab 13:50 DIMM installation 14:42 Water Cooling 16:49 Why Mainframes? 18:20 Fiber 19:47 Conclusions Errata: Around 5:30, the CPUs are LGA(Land Grid Array), not PGA At about 7:07 should be 200 cores, not 256. At 20:03, they now achieve eight nines of reliability for both z16 and its Linux-only counterpart, the IBM LinuxONE 4. In a LinuxONE config, max RAM is 48TB.
