====連結內文片段 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 ===event log=== B 0 I 06/23/12 09:21:57 Device 'Device_1_1' (1/1) has been initialized.

使用Write-through去穿透cache會重創parity性能... 這個取捨需要考慮.. http://www.pcdvd.com.tw/showthread.php?t=972169 HPT透過SHI可提供一種SMART GUI Monitoring.. 可以定期觀察各PD的當前SMART狀態.. 定期排程verify會是相當重要的.. 這個操作會包括CC以及Media Scans.. HPT 6Gb/s IOC RAID HBA僅僅支持一些基礎的維護機能 可以認為他的功能比Intel RSTe稍微強一些... 但是由於價格上的差異.. 就不要有所挑剔了...  從你當前提供的event log來看.. 可以知道這僅僅只是PD failed的提醒.. 至於他是甚麼問題引發.. log並無提供詳細訊息.. 如果RAID driver還可以偵測到該PD.. 透過SHI查看當前PD狀況也許可以得知一些資訊.. 此文章於 2012-06-30 09:57 PM 被 vxr 編輯. |

前幾天拿了一些消費級的 1TB 硬碟接上 9260-8i 來試試看
一開始建立 VD 跟跑測試都還 OK ,但一重開機馬上就幾顆抓不到 ... 還是乖乖把老老的 ES 硬碟拿出來用 ,至少不會有三不五時掉隊的問題

請問樓主drop的那顆後來知道是為什麼嗎?
打算用兩顆ST2000DM001把四顆6400AAKS/AALS(混用)換掉 把原本的RAID0 / RAID10換成 RAID0 / RAID1 減少硬碟節能減碳一下... |
