内容説明 The definitive guide to UCS and the Cisco(R) Data Center Server: planning， architecture， components， deployment， and benefits With its new Unified Computing System (UCS) family of products， Cisco has introduced a fundamentally new vision for data center computing: one that reduces ownership cost， improves agility， and radically simplifies management. In this book， three Cisco insiders thoroughly explain UCS， and offer practical insights for IT professionals and decision-makers who are evaluating or implementing it. The authors establish the context for UCS by discussing the implications of virtualization， unified I/O， large memories and other key technologies， and showing how trends like cloud computing and green IT will drive the next-generation data center. Next， they take a closer look at the evolution of server CPU， memory， and I/O subsystems， covering advances such as the Intel(R) XEON(R) 5500， 5600， 7500， DDR3 memory， and unified I/O over 10 Gbps Ethernet. Building on these fundamentals， the authors then discuss UCS in detail， showing how it systematically overcomes key limitations of current data center environments. They review UCS features， components， and architecture， and demonstrate how it can improve data center performance， reliability， simplicity， flexibility， and energy efficiency. Along the way， they offer realistic planning， installation， and migration guidance: everything decision-makers and technical implementers need to gain maximum value from UCS–now， and for years to come.
