商品描述

Data is the lifeblood of modern business, and modern data centers have extremely demanding requirements for size, speed, and reliability. Storage Area Networks (SANs) and Network Attached Storage (NAS) allow organizations to manage and back up huge file systems quickly, thereby keeping their lifeblood flowing. W. Curtis Preston's insightful book takes you through the ins and outs of building and managing large data centers using SANs and NAS.

As a network administrator you're aware that multi-terabyte data stores are common and petabyte data stores are starting to appear. Given this much data, how do you ensure that it is available all the time, that access times and throughput are reasonable, and that the data can be backed up and restored in a timely manner? SANs and NAS provide solutions that help you work through these problems, with special attention to the difficulty of backing up huge data stores.

This book explains the similarities and differences of SANs and NAS to help you determine which, or both, of these complementing technologies are appropriate for your network. Using SANs, for instance, is a way to share multiple devices (tape drives and disk drives) for storage, while NAS is a means for centrally storing files so they can be shared. Preston exams each technology with a vendor neutral approach, starting with the building blocks of a SAN and how they can be assembled for effective storage solutions. He covers day-to-day management and backup and recovery for both SANs and NAS in detail.

Whether you're a seasoned storage administrator or a network administrator charged with taking on this role, you'll find all the information you need to make informed architecture and data management decisions. The book fans out to explore technologies such as RAID and other forms of monitoring that will help complement your data center. With an eye on the future, other technologies that might affect the architecture and management of the data center are explored. This is sure to be an essential volume in any network administrator's or storage administrator's library.

商品描述(中文翻譯)

數據是現代企業的命脈,現代數據中心對於容量、速度和可靠性有極高的要求。存儲區域網絡(SAN)和網絡附加存儲(NAS)使組織能夠快速管理和備份大型文件系統,從而保持其命脈流動。W. Curtis Preston的這本富有洞察力的書籍將帶領您深入了解使用SAN和NAS構建和管理大型數據中心的方方面面。



作為網絡管理員,您知道多TB數據存儲是常見的,而PB數據存儲也開始出現。在擁有如此多數據的情況下,您如何確保數據始終可用,訪問時間和吞吐量合理,並且數據可以及時備份和恢復?SAN和NAS提供了解決這些問題的解決方案,特別關注備份大型數據存儲的困難之處。



本書解釋了SAN和NAS的相似之處和不同之處,以幫助您確定哪種或兩種互補技術適合您的網絡。例如,使用SAN是共享多個設備(磁帶驅動器和磁盤驅動器)進行存儲的一種方式,而NAS是集中存儲文件以便共享的一種方式。Preston以供應商中立的方式檢視每種技術,從SAN的構建模塊和如何組裝有效的存儲解決方案開始。他詳細介紹了SAN和NAS的日常管理以及備份和恢復。



無論您是經驗豐富的存儲管理員還是負責承擔這一角色的網絡管理員,您都能找到所有需要的信息,以便做出明智的架構和數據管理決策。本書還探討了RAID和其他形式的監控等技術,這些技術將有助於補充您的數據中心。同時,本書還關注可能影響數據中心架構和管理的未來技術。這本書無疑是任何網絡管理員或存儲管理員圖書館中的重要參考資料。
