[新聞]虛擬化不一定是萬靈丹

作者:Peachwa & Neversay on 八月 17, 2007 Posted in RSS | | 觀看文章來源

From Taiwan.CNet.com:記者曠文溱/台北報導  14/08/2007 伺服器虛擬化(virtualization)固然有許多好處,但是從專家眼中看來,若是認為所有資料中心管理問題都可以迎刃而解,可能過於天真。 在國內企業逐漸將虛擬化應用由測試端延伸至生產(production)面之際,專家提醒道,虛擬化固然的確可以提高伺服器使用率,節省硬體和電力、樓板 空間成本;但是短時間來說,管理成本並不會因此減少,甚至可能比原本管理實體機器更為費力、複雜。另外,對於一些極度消耗處理器、I/O資源的應用程式而 言,例如大型資料庫和線上交易,依靠虛擬化軟體來和硬體層溝通,也會產生效能相對緩慢的問題。 「企業只是把原本管理10台實體伺服器的能耐,轉變為管理10台虛擬機器(virtual machine),費的功夫並不會比較少,」Unisys技術專案經理林家慶說。
