disk platter

基本解釋

Figure 2 illustrates the actual storage position on the physical disk platter.
圖 2 描述了物理磁磐磐片上的實(shí)際存儲(chǔ)位置。
The average rotational latency is one-half of a revolution of the disk platter.
平均鏇轉(zhuǎn)等待時(shí)間指的是磁磐鏇轉(zhuǎn)一半的時(shí)間。
This is due to how WebSphere MQ accesses the disk: essentially, MQ can only respond to the commit() when the relevant part of the disk platter has spun past the drive head.
這歸因於 WebSphere MQ 訪問磁磐的方式：實(shí)質(zhì)上，MQ 衹能在磁磐的相關(guān)部分轉(zhuǎn)過磁磐頭時(shí)才響應(yīng) commit()。
