IBM zEnterprise 196 Technical Guide
The popularity of the Internet and the affordability of IT hardware and software have resulted in an explosion of applications, architectures, and platforms. Workloads have changed. Many applications, including mission-critical ones, are deployed on a variety of platforms, and the System z® design has adapted to this change. It takes into account a wide range of factors, including compatibility and investment protection, to match the IT requirements of an enterprise. The zEnterprise System consists of the IBM zEnterprise 196 central processor complex, the IBM zEnterprise Unified Resource Manager, and the IBM zEnterprise BladeCenter® Extension. The z196 is designed with improved scalability...

The popularity of the Internet and the affordability of IT hardware and software have resulted in an explosion of applications, architectures, and platforms. Workloads have changed. Many applications, including mission-critical ones, are deployed on a variety of platforms, and the System z® design has adapted to this change. It takes into account a wide range of factors, including compatibility and investment protection, to match the IT requirements of an enterprise. This IBM® Redbooks® publication discusses the IBM zEnterprise System, an IBM scalable mainframe server. IBM is taking a revolutionary approach by integrating separate platforms under the well-proven System z hardware manageme...
Security for Linux on System z
No IT server platform is 100% secure and useful at the same time. If your server is installed in a secure vault, three floors underground in a double-locked room, not connected to any network and switched off, one would say it was reasonably secure, but it would be a stretch to call it useful. This IBM® Redbooks® publication is about switching on the power to your Linux® on System z® server, connecting it to the data and to the network, and letting users have access to this formidable resource space in a secure, controlled, and auditable fashion to make sure the System z server and Linux are useful to your business. As the quotation illustrates, the book is also about ensuring that, befo...
Running Linux on IBM System Z9 and ZSeries Under Z/VM
This IBM Redbooks publication discusses running Linux under z/VM on IBM System z9 and zSeries platforms. We describe enhancements available in z/VM Version 5.1. The intended audience for this book is IT administrators responsible for installing and configuring z/VM 5.1 systems running Linux guests. Using Fibre Channel Protocol (FCP), z/VM 5/1 can be installed on and operate from SCSI disks. Configured as emulated Fixed Block Architecture (FBA) disks, z/VM 5.1 can use FCP-attached disks for its system paging, spooling, directory, and minidisks. z/VM 5.1 adds new functions for Virtual Switches (VSWITCH). For increased network security, guests must have authorization before connecting to a VSWITCH. z/VM 5.1 introduces VSWITCH Layer 2 support. Operating at Layer 2, a VSWITCH delivers and receives network traffic in Ethernet frames. This provides the ability to handle non-IP protocols such as SNA, NetBIOS, and IPX. In addition, Layer 2 support reduces network latency and CPU overhead.
IBM ZEnterprise System Technical Introduction
Recently, the IT industry has seen an explosion in applications, architectures, and platforms. With the generalized availability of the internet and the appearance of commodity hardware and software, several patterns have emerged that have gained center stage. Workloads have changed. Many applications, including mission-critical ones, are deployed in heterogeneous infrastructures. System z® design has adapted to this change. IBM® has a holistic approach to System z design, which includes hardware, software, and procedures. It takes into account a wide range of factors, including compatibility and investment protection, which ensures a tighter fit with IT requirements of an enterprise. This...
