This IBM® Redbooks® publication provides guidance about how to configure, monitor, and manage your IBM System Storage® DS8800 and DS8700 storage systems to achieve optimum performance. It describes the DS8800 and DS8700 performance features and characteristics, including IBM System Storage Easy Tier® and DS8000® I/O Priority Manager. It also describes how they can be used with the various server platforms that attach to the storage system. Then, in separate chapters, we detail specific performance recommendations and discussions that apply for each server environment, as well as for database and DS8000 Copy Services environments. We also outline the various tools available for monitoring and measuring I/O performance for different server environments, as well as describe how to monitor the performance of the entire DS8000 storage system. This book is intended for individuals who want to maximize the performance of their DS8800 and DS8700 storage systems and investigate the planning and monitoring tools that are available. The IBM System Storage DS8800 and DS8700 storage system features, as described in this book, are available for the DS8700 with Licensed Machine Code (LMC) level 6.6.2x.xxx or higher and the DS8800 with Licensed Machine Code (LMC) level 7.6.2x.xxx or higher. For information about optimizing performance with the previous DS8000 models, DS8100 and DS8300, see the following IBM Redbooks publication: DS8000 Performance Monitoring and Tuning, SG24-7146.
This IBM® RedpaperTM publication describes the concepts and functions of the IBM System Storage® DS8000® I/O Priority Manager. The DS8000 I/O Priority Manager enables more effective storage consolidation and performance management combined with the ability to align quality of service (QoS) levels to separate workloads in the system. With DS8000 I/O Priority Manager, the system can prioritize access to system resources to achieve the volume's desired QoS based on defined performance goals (high, medium, or low) of any volume. I/O Priority Manager constantly monitors and balances system resources to help applications meet their performance targets automatically, without operator intervention. Starting with DS8000 Licensed Machine Code (LMC) level R6.2, the DS8000 I/O Priority Manager feature supports open systems and IBM System z®. DS8000 I/O Priority Manager, together with IBM z/OS® Workload Manager (WLM), provides more effective storage consolidation and performance management for System z systems. Now tightly integrated with Workload Manager for z/OS, DS8000 I/O Priority Manager improves disk I/O performance for important workloads. It also drives I/O prioritization to the disk system by allowing WLM to give priority to the system's resources automatically when higher priority workloads are not meeting their performance goals. Integration with zWLM is exclusive to DS8000 and System z systems. The paper is aimed at those who want to get an understanding of the DS8000 I/O Priority Manager concept and its underlying design. It provides guidance and practical illustrations for users who want to exploit the capabilities of the DS8000 I/O Priority Manager.
This authoritative history of Japan’s elite warrior class separates fact from myth as it chronicles centuries of samurai combat, culture, and legend. In Legends of the Samurai, Hiroaki Sato examines the history of these medieval Japanese warriors, as well as the many long-standing myths that surround them. In doing so, he presents an authentic and revealing picture of these men and their world. Sato’s masterful translations of original samurai tales, laws, dicta, reports, and arguments are accompanied by insightful commentary. With incisive historical research, this volume chronicles the changing ethos of the Japanese warrior from the samurai's historical origins to his rise to political power. A fascinating look at Japanese history as seen through the evolution of the samurai, Legends of the Samurai stands as the ultimate authority on its subject.
Throughout history, Japanese women have excelled in poetry - from the folk songs of the Kojiki (Record of Ancient Matters) compiled in 712 and the court poetry of the 9th to the 14th centuries, on through the age of haikai and kanshi to the 19th century, into the contemporary period when books of women's poems have created a sensation.This anthology presents examples of the work of more than 100 Japanese women poets, arranged chronologically, and of all the major verse forms: choka, tanka, haikai (haiku), kanshi (verse written in Chinese), and free verse. The poems describe not just seasonal changes and the vagaries of love - which form the thematic core of traditional Japanese poetry - but also the devastations of war, childbirth, conflicts between child-rearing and work, experiences as refugees, experiences as non-Japanese residents in Japan, and more.Sections of poetry open with headnotes, and the editor has provided explanations of terms and references for those unfamiliar with the Japanese language. Other useful tools include a glossary of poetic terms, a chronology, and a bibliography that points the reader toward other works by and about these poets. There is no comparable collection available in English.Students and anyone who appreciates poetry and Japanese culture will treasure this magnificent anthology. Editor and translator Hiroaki Sato is a past winner of the PEN America translator prize and the Japan-United States Friendship Commission's 1999 literary translation award.
In recent years, the treatment of Rheumatoid Arthritis has undergone tremendous changes due to methotrexate and biologics in large part. Until a decade ago, avoiding joint destruction in rheumatoid arthritis was not realistic for rheumatologist. However, prevention of joint deterioration is now possible, and the quality of life of patients with rheumatoid arthritis in long-term has been able to improve by advances in treatment. However, there are still many problems to be overcome before achieving the treatment of rheumatoid arthritis. All of review articles presented on this book are explaining treatment, basic research, and patient care of rheumatoid arthritis with innovative perspective and ideas. I hope that the ideas that have been described in these articles help the reader to resolve the outstanding issues in rheumatoid arthritis.
