IBM has rolled out a new generation of mainframes – the z15 – that not only bolsters the speed and power of the Big Iron but promises to integrate hybrid cloud, data privacy and security controls for modern workloads.
On the hardware side, the z15 mainframe systems ramp up performance and efficiency. For example IBM claims 14 percent more performance per core, 25 percent more system capacity, 25percent more memory, and 20 percent more I/O connectivity than the previous iteration, the z14 system.
IBM also says the system can save customers 50 percent of costs over operating x86-based servers and use 40 percent less power than a comparable x86 server farm. And the z15 has the capacity to handle scalable environments such as supporting 2.4 million Docker containers on a single system.
