比起data,錢是小事u.有問題詢問
如果作RAID0 RAID5,如果想要更換其中幾顆硬碟的資料(也就是換新硬碟上去) 不知道處理起來回不會很麻煩 舉例現在有1T*5個硬碟作RAID5,可以乘載4T的數據 我想要更換其中1~2顆硬碟(1~2T數據)下來放上2顆新硬碟上去不知道允不允許這樣做 另外如果copy2顆硬碟(2T數據)到其他硬碟再把它作對換 (把RAID的2T和copy數據過去未做RAID的2T兌換) 不知道這樣做會不會怎麼樣,又硬碟廠牌不同會出問題嗎? 最後一個問題,這張RAID卡可以支援單顆2T的硬碟嗎,亦或是可以更新FW讓它支援到單顆2T嗎? |

如果換硬碟 會需要重新建立 RAID 需要重建多久這個要看電腦和卡是否有F/W的CHIP Key RAID Features • Supports 8 direct-attached or up to 256 SATA or SAS disk drives using SAS expanders • RAID levels 0, 1, 1E, 5, 5EE, 6, 10, 50 and 60 • Quick initialization • Online Capacity Expansion • Copyback Hot Spare • Dynamic caching algorithm • Native Command Queuing (NCQ) • Background initialization • Hot-plug drive support • RAID Level Migration • Hot spares – global, dedicated, and pooled • Automatic/manual rebuild of hot spares • SAF-TE enclosure management • Configurable stripe size • S.M.A.R.T. support • Up to 512TB array sizes • Multiple arrays per disk drive • Bad stripe table • Dynamic sector repair • Staggered drive spin-up • Bootable array support • Optimized Disk Utilization 都支援到那麼大了 單分割2TB應該是沒問題 現在出的卡要是還有這個問題就該打屁股了 你說你要把 RAID 裡面的資料COPY到別的硬碟裡面去 我是很久沒碰 RAID 了 我記得好像不是每個 RAID 硬碟都可以直接 COPY 普通狀況下是無法讀取的 (離開 RAID 卡後) RAID 1 和 10 是可以 (如果沒記錯) RAID 0 不可以 RAID 5 沒這樣玩過 不確定 而且 RAID 卡會記得硬碟 另外 RAID 5 我記得不可以壞兩個硬碟 壞兩個 RAID 就掛了 就因為如此才有 RAID 6 以上如果有錯請糾正  |
