在一個超大型的storage pool建置多個VD,
搭配Hotspare HDD可以用共用並根據特性設定為HSP, DHSP, PHSP,GHSP.
使用Copyback功能才能將此HSP(Hotspare HDD)空出來並且支援各組VD故障狀況..
否則將HSP經過rebuild融入某組VD內.此大型Raid Pool沒有Hot Spare HDD 是比較高風險的
====

ohohoh~這才是HSP真正的價值所在呀!!不單只是被單獨的VD所使用而且做Copyback的理由也在裡面...了解了多謝

"27xxSGL不是IOP..."
改太晚了...被您先看見了XD~ 對2720sgl為半放棄狀態中

"我不太清楚"加入的硬碟成為新的HSP，這樣不就少了個copyback的動作?"這個意思..."
原意是把插入到bad slot的新PD變成新hot spare碟，元hot spare碟直接加入raid array。
不過您給的連結已經有說明到了。

"tomshardware那篇測試有些問題.."
現在來看他那篇光把不同等級的卡擺在同一個籃子測的問題就已經很大了...


現階段我還時先拿HPT當入門，等哪時荷包滿一點時再來試LSI raid6+hsp...現在光想到就痛@@"


原先設Write Back...但之後想犧牲點效能換安全性所以現在設Write Through
