電腦硬體的快速發展讓雲端運算得以更加多元，但多數情況下系統資源並沒由於科技的快速發展與硬體成本快速下降，因而造就大型伺服器效能越強大以及個人電腦的普及化。雖然有強大的系統，但是實際上效能並非完全使用，造成資源閒置的情形，因此許多的大型企業導入了虛擬化的技術，希望能完整的使用到伺服器的資源。為了要企業可以評估整體的系統效能，VMware因此提供VMmark測試軟體來讓企業有一個測試標準。藉由這個測試，可以讓企業評估投資什麼樣的硬體可達到最大效益。
本論文利用VMMwark來測試來比較在企業環境下使用儲存裝置的差異。藉由郵件伺服器、電子商務模擬、 Web2.0模擬、虛擬機的遷移，來測試整體的系統效能。測試時，我們將儲存裝置進行實作，將成績進行平均來進行比較。另外，儲存裝置成本部分我們到官方網站上取得建議售價，藉此計算整體的成本。
最後測試結果，SAN所得的整體成績為NAS的2倍，而NAS與SAN的成本差異約有17.8倍的差價。相對於所得成績，所付出的成本效益是在合理的範圍內。

Due to the rapid development of technology with the price less, thus it is easy to build the highly performance server and making the popularity of powerful personal computers. Although there is a strong system, but in fact the performance are not completely utilities, resulting in west computing power situation. There is many enterprises introduced virtualization technology, hoping to utilities the server resources. To exam the overall system performance, VMware provide checking software called VMmark to allow company to measure the system performance. With an impartial measure, the enterprise evaluates what kind of hardware investment can reach maximum efficiency. In this thesis, VMmark evaluate the performance of scope of enterprise environment on differences storage devices.
By examining the following scenario on mail servers, e-commerce simulation and Web2.0 simulation, it is compares the storage devices performance on each time doing the deployment and system integration in virtual environment to measure the overall system performance. Evaluation methods are that ranking the average score VMmark achievement level with the market price of performance indicator.
Finally, the result is that the VMmark total score of SAN is twice for NAS, but the cost of performance indicators shows NAS is 17.8 time cheaper than SAN. Within the expected of resulting achievements, the cost is paid within a reasonable range.
