Do you know about Linux? Maybe you are a user of the Linux operating system, but do you know how the Linux operating system is managed on the mainframe? This article describes the complexity of Linux management on the mainframe. What is mainframe performance management? In t

. Physical volume, it is smaller than the z10 large machine, and can be placed on no overhead floor or no overhead floor. Like z196, enterprises can wiring from the top or bottom of the cabinet and use high-voltage DC power. Many people may be concerned about power consumption. As IBM said, power consumption is definitely not a problem. This device uses less power than a dryer. In fact, I have not seen many enterprises ready and willing to purchase z1

IBM's large machines are looking for new looks. They have upgraded to the private cloud and hybrid cloud markets, providing faster processing capabilities, lower prices, and improved memory. The new zEnterprise mainframe is zEC12 and the processor is 5.5 GHz, which is much better than z196. IBM also extended level 2, level 3, and Level 4 buffering and improved boot settings. This means that zEC12 is faster

According to foreign media reports, recently, IBM released its Z13 mainframe platform, the new product equipped with a variety of chip hardware innovation technology to achieve mobility, analytical applications and security-driven workload acceleration. The Z13 system can support up to 10TB of memory and up to 8000 virtual servers.John Birtles, director of IBM Sy

Article title: IBM's new mainframe fully adopts Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. IBM is using Linux products to reduce host costs to improve competitiveness. At present, the Linux system lineup has been

For Open product machines with X86 architecture, IBM's closed platform series can be said to be another "system world ". Ibm z series mainframe, Z/OS Operating System IBM I Series/as400 middleware, I/OS Operating System IBM p s

, effective and friendly service interface. The operating system is usually the closest to the hardware of a layer of system software, it is the hardware to transform the bare metal into a fully functional virtual machine, making the use and management of computer systems more convenient, more efficient use of computing resources, the upper layer of the application can be more than the hardware provides mor

OS/400 and IBM I server families, A four-core 4.2 GHz processor with a Power 770 + rating of 90000 CPW, about 7500 CPW per core. This Power7 + chip with a four-core operating speed of 3.8 GHz is rated as 110000 CPW, about 6875 CPW per core. When you add processors to these systems, increase the number of cores to 48 or 64, symmetric Multi-processing and non-cons
