Sommario/riassunto |
|
Energy Efficient Servers: Blueprints for Data Center Optimization introduces engineers and IT professionals to the power management technologies and techniques used in energy efficient servers. The book includes a deep examination of different features used in processors, memory, interconnects, I/O devices, and other platform components. It outlines the power and performance impact of these features and the role firmware and software play in initialization and control. Using examples from cloud, HPC, and enterprise environments, the book demonstrates how various power management technologies are utilized across a range of server utilization. It teaches the reader how to monitor, analyze, and optimize their environment to best suit their needs. It shares optimization techniques used by data center administrators and system optimization experts at the world’s most advanced data centers. |

Sommario/riassunto |
|
The United States, and the West in general, has always organized society along bipolar lines. We are either gay or straight, male or female, white or not, disabled or not. In recent years, however, America seems increasingly aware of those who defy such easy categorization. Yet, rather than being welcomed for the challenges that they offer, people living the gap are often ostracized by all the communities to which they might belong. Bisexuals, for instance, are often blamed for spreading AIDS to the heterosexual community and are regarded with suspicion by gays and lesbians. Interracial couples are rendered invisible through monoracial recordkeeping that confronts them at school, at work, and on official documents. In Hybrid, Ruth Colker argues that our bipolar classification system obscures a genuine |

|

understanding of the very nature of subordination. Acknowledging that categorization is crucial and unavoidable in a world of practical problems and day-to-day conflicts, Ruth Colker shows how categories can and must be improved for the good of all. |
