淺談圖書館虛擬化環境建置成本效益分析與應用

Discussion on Cost-benefit Analysis and Application of Library Virtualization Environment Construction

在數位網路資源所佔館藏比例不斷攀升的今日，館內提供讀者使用的資訊設備種類及數量不斷增加，功能亦越趨複雜，對於管理各項電腦設備所占用館員的時間與工作量之比重將逐漸加重，而虛擬化技術（Virtualization）之應用，已逐漸普及於圖書館資訊機房，其效益在於提升伺服主機運算資源使用率及減少實體機器的數量，能為電腦設備管理帶來許多便利性與效率，並具有降低維護成本與節能減碳等優點。本文以國立故宮博物院南部分院亞洲藝術文化資料中心為例，藉由文獻、採購成本及管理經驗等分析，探討虛擬化技術，試論簡化電腦軟、硬體管理與降低營運維護成本之優勢，以提供圖書館規劃與建置虛擬環境之參考。

Today the ratio of digital network resources in library collections is continuously rising. The type and number of IT equipments in a library are increasing with their functions more and more sophisticated. The time and workload for librarians to manage IT equipments are increasing. Virtualization has been widely used at library IT server rooms. Its benefits are increasing the computing resource usage ratio, reducing the number of physical machines, and bringing convenience and efficiency for IT equipment management. It also reduces the maintenance costs and saves energy. This article takes the example of the Asian Art and Culture Information Center at the Southern Branch of the National Palace Museum. Through analyzing literature, purchasing costs, and management experience, this article discusses the advantages of virtualization technology for future reference in future planning of virtual environment in a library.
