IT environments in organizations today face more challenges than ever before. Server rooms are crowded, infrastructure costs are climbing, and right-sizing systems is often problematic. In order to contain costs there is a push to use resources more wisely by minimizing waste and maximizing the return on investment. Virtualization technology was developed to answer these objectives. More and more organizations will deploy (or are in the process of deploying) some form of virtualization. However, parts of an organization's systems may use earlier storage equipment. In these contexts, knowing how to migrate from physical, often direct-attached storage, to a virtual storage environment becomes valuable. This IBM® Redbooks® publication introduces techniques to use for the migration of storage from physical to virtual environments and introduces several new features in POWER6® technology-based systems. These features include: The chkdev command, added in Virtual I/O Server 2.1.2 FP22 to assist in identifying physical-to-virtual candidates and to ensure that device identification is consistent Extensive use of NPIV technology for both disk and tape devices The use of file-backed optical technology to present virtual CD media as a means of restoration

For the first time it is possible to deploy an integrated hardware platform that brings mainframe and distributed technologies together: a system that can start to replace individual islands of computing and that can work to reduce complexity, improve security, and bring applications closer to the data that they need. With the zEnterprise System a new concept in IT infrastructures is being introduced: zEnterprise ensembles. A zEnterprise ensemble is a collection of highly virtualized diverse systems that can be managed as a single logical entity where diverse workloads can be deployed. Ensembles, together with the virtualization, flexibility, security, and management capabilities provided by the zEnterprise System are key to solving the problems posed by today's IT infrastructure. The zEnterprise System consists of three components: - IBM® zEnterprise Central Processor Complex (CPC) The zEnterprise CPC can either be a zEnterprise 196 (z196) or a zEnterprise 114 (z114). Both zEnterprise CPCs offer z/OS, z/VSE, and z/TPF operating systems, as well as the ability to run many virtualized Linux servers under the z/VM operating system. - IBM zEnterprise BladeCenter Extension (zBX) The zBX provides the capability to run the wide variety of applications typically found in UNIX and x86 architectures. The zBX supports select POWER7 blades running AIX and System x blades running Linux on System x and Microsoft Windows. - IBM zEnterprise Unified Resource Manager Unified Resource Manager runs in the Hardware Management Console (HMC). It provides integrated management across all elements of the zEnterprise System. This IBM Redbooks® publication discusses how to plan and implement an ensemble, using the zEnterprise Unified Resource Manager. This book assumes a knowledge of IT systems, networks, and storage devices.
