隨著網際網路的便利與發達,且近幾年行動裝置逐漸成熟,雲端議題已被重視許久,因此,綜合以上的發展使得物聯網(Internet of Thing;IOT)成為未來的一個重要趨勢和商機。企業型產品如伺服器、儲存設備等支撐著這些產業發展及應用,因此,企業型產品在穩定性上有著嚴格的要求。
本研究將探討伺服器中硬碟讀寫效能在振動環境下的變化。針對影響效能的硬盤托盤減振方案關鍵因子如:減振材料與硬碟總接觸面積、減振材料厚度、減振材料種類及托盤導軌與硬碟支架壓縮量,進行了研究。透過Iometer 軟體量測硬碟讀寫和原始硬碟托盤設計之實驗數據來做比較分析。
實驗結果表明,導入最佳參數設計:減振材料與硬碟接觸總面積(386.6mm2)、減振材料厚度(1.3 mm) 、減振材料種類(TPE 硬度 55 度) 及托盤導軌與硬碟支架壓縮量(0.3mm)之後,其硬碟讀取效能優於原始設計。
導入最佳設計之後,在系統正常運作的最大風扇轉速90% PWM,硬碟讀寫值從24%提升至80%。
As the internet has developed and becomes more convenient,
mobile devices get growth in recent years and cloud topics have
been emphasized, for a long time. Therefore, all of these make IOT
(Internet of Thongs) become an important future trends and
opportunities.
Products, such as servers, storage devices and other
application equipments, support the development of these
industries. Therefore, the product stability is the most important
concern. The objective of this study is to investigate the effect
of heavy factors on the throughput performance of hard disk in an
operating server.
The key factors such as damping material contact area with hard
disk, thickness of damping material, type of damping material and
compressed distance of rail of hard disk carrier affecting the
throughput performance of vibration isolation solution of hard
disk carrier were studied.
A IOmeter software was applied to measure the hard disk
throughput performance and to compare throughput performance
between original design and optimal design of hard disk carrier.
Experimental results shows optimal design by implementing
these key factors, damping material contact area with hard disk
is 386.6mm2, thickness of damping material is 1.3 mm, type of
damping material is TPE Hardness 55 degree and compressed distance
of rail of hard disk carrier is 0.3 mm, having throughput
performance better with original design. With optimal design, hard
disk throughput impediment increases from 24% to 80% with maximum
fan speed of 90%PWM of the system.
