大家好,我看了lovelpc網兄發表的這篇開箱文[開箱!] 拯救你的孤兒硬碟 - ICY DOCK MB994SP-4S 硬碟抽取盒 !,覺得十分好用,便也去買了一個,
之後我裝上三顆WD SATA 320GB 黑標WD3200BEKT硬碟,用HP SmartArray P400 RAID卡,做成RAID-5磁碟,存取使用都很正常,但是我測試熱插拔功能時,先拔除一顆硬碟,這時RAID仍正常存取,然後再插入硬碟要看它Rebuild時,就發現RAID掛了,因為有另一顆硬碟也變成Failed,我反覆試了幾次,發現硬碟插入瞬間似乎會導致另一硬碟瞬斷,在抽取盒背面有兩條電源輸入,一條是給上面左右兩個插槽用,一條給下面兩個插槽用,當硬碟插上時,會使相同電路的另一顆硬碟瞬斷,所以RAID就崩潰了,但是不同電路的上下硬碟在插拔時就不會有影響。
我不知這是產品故障還是正常現象,想請問各位有無這方面的建議。謝謝啦。

Replacing hard drives
The most common reason for replacing a hard drive is that it has failed. However, another reason is to
gradually increase the storage capacity of the entire system.
If you insert a hot-pluggable drive into a drive bay while the system power is on, all disk activity in the
array pauses for a second or two while the new drive is spinning up. When the drive has achieved its
normal spin rate, data recovery to the replacement drive begins automatically (as indicated by the
blinking Online/Activity LED on the replacement drive) if the array is in a fault-tolerant configuration.
If you replace a drive belonging to a fault-tolerant configuration while the system power is off, a POST
message appears when the system is next powered up. This message prompts you to press the F1 key to
start automatic data recovery. If you do not enable automatic data recovery, the logical volume remains
in a ready-to-recover condition and the same POST message appears whenever the system is restarted.
還有HP SA-P400是一片SAS Smart Array controllers這樣你是把它接SATA用
接是可以吧只是會少了點什麼3Gb SAS/1.5Gb SATA 變SATA第一代的規格,像是缺了NCQ
還有SATA 1.5Gb/s 的SATA熱插拔功能可能還不太完備 可能這塊要上SAS 3G會比較優

以這個價位的插拔盒, 背板不會有什麼電路加強的設計
應該只是單純的訊號連接而已
RAID 卡判定很靈敏, 同一條電源上的硬碟瞬間有狀況, 那 RAID 掛掉是合理的
如果 RAID 卡沒有相關的參數可調整, 換四個獨立的揷拔盒+電源獨立或許比較穩定
另外就是高檔的東西建議找有認證過的相關週邊
否則 RAID 卡原廠一定跟你說: "換掉那個插拔盒!!!"
