    The cache (e.g. level 3) is doubled from the previous generation z14, while the "L4 cache increased from 672MB to 960MB, or +43%" with the new add-on chip system controller (SC) SCM. Both it and all levels of cache in the main processor from level 1 use eDRAM, instead of the traditionally used SRAM. "A five-CPC drawer system has 4800 MB (5 x ...

    The HMC is a PC connected to the mainframe and emulates the Support Element. All preceding zSeries mainframes used a modified version of OS/2 with custom software to provide the interface. System z9's HMC no longer uses OS/2, but instead uses a modified version of Linux with an OS/2 lookalike interface to ease transition as well as a new interface.
