我建議一個想法就是你買的Hitachi HDD要把每顆ERC全部都開起來... 可以使用smartontool.... 你有沒有開ERC阿...:confused:... |

還沒玩到那麼遠啊 4224 已經拆掉明天要還了 |

先說一下... 接在MR9265上就沒辦法直接用工具開ERC了.. 一個策略就是利用主機板上的SATA port接上去開erc.. |

:confused: 不懂 :stupefy: |

因為像smartontool無法識別LSI MR的RAID Controller... 接在MB的SATA port上.. 開IDE模式... 就可以利用smartontool去識別開啟HDD.... |

別嚇我阿,我這個週末要趕快試試。 我的應該已經超過30天了,我大概還有6個bay完全還沒有試過.... |

請問vxr您Power supply的線是從一個case拉到另外一個case嗎? 如果是兩顆獨立的power supply的話,要怎麼連動呢? 我還有一個問題就是,如果我瘋了再買一個Norco4020: 1. 我可以把我1880-24上面的其中5個internal SAS port用在原本的chasis, 然後把檔板上的external port接到第二個chasis中的SAS expander裡面嗎? 2. SAS expander好像有啥Dual link的東西,請問那個有啥好處呢?如果要用dual link, 是否要用掉兩個我1880上面的SAS port? 3. intel sas expander只有24個port, 如果我跑dual link, 是否只有16可以用了? 4. 請問這樣子可能會有什麼問題呢? 雖然我這麼做的機會短期內不太大,不過還是想問問。 |

"請問vxr您Power supply的線是從一個case拉到另外一個case嗎? 如果是兩顆獨立的power supply的話,要怎麼連動呢?" 兩顆獨立的PSU... 沒連動.. 不管他... 反正透過IPMI去監控.... "1. 我可以把我1880-24上面的其中5個internal SAS port用在原本的chasis, 然後把檔板上的external port接到第二個chasis中的SAS expander裡面嗎?" 沒差... "2. SAS expander好像有啥Dual link的東西,請問那個有啥好處呢?如果要用dual link, 是否要用掉兩個我1880上面的SAS port?" Dual Link就要牽扯到SAS的特徵... Dual Port.... 你要Dual Link... 那expander backplane應該會有兩顆expander chip去做failover設計... 這張圖會讓你明白Dual Link的真正用意... ![]() 3. intel sas expander只有24個port, 如果我跑dual link, 是否只有16可以用了? 我不曉得你這個要怎麼做dual link..... 你要接在哪個機櫃??.... |
SAS 還可做failover +Cluster share
在虛擬化 Storage 中 以便宜高速 SAS 連結替代FC ,ISCSI 才是正確設計之道 ![]() 剛好翻到 http://communities.vmware.com/threa...tart=0&tstart=0 設定方式還比ISCSI ,NFS ,FC 簡單多.... I/O 把可憐的FC 8G 電假 也不用做可憐的Gigabit 802.3AD 成本大概是 1/5 ..>< 此i/o為 5 顆15000轉 SAS 硬碟 ![]() 原廠設定文件 http://www.dell.com/downloads/globa...yment-guide.pdf Hyper V 設法 http://www.dell.com/downloads/globa...lementation.pdf MD3200 低階為單控制器 共有 2 SAS IN 2 SAS Out port 不帶硬碟大概 20 萬不到 版卡的話 拿NT 4000 ~ 7000 HBA 都可 另外下面幾種機器也許也行 1. IBM DS3500 比起MD3200 可共用 SAS +FC +SCSI 多混合 價格比較高 介紹簡報 http://wenku.baidu.com/view/e133ccf...7302763ad8.html http://wenku.baidu.com/view/fe338a2...ccda38a061.html http://wenku.baidu.com/view/5c8cf00...37ee061984.html http://wenku.baidu.com/view/c166a51...192279e974.html Redbook 設定SAS RDC in Linux http://www.redbooks.ibm.com/redpieces/pdfs/sg247914.pdf DS3500貴的不是硬體 是軟體 超過4 個Lun 要額外軟體授權費 2.HP P2000 G3 http://h10010.www1.hp.com/wwpc/us/e...93-4118559.html 3.一般主機 ZFS + Comstar 做SAS Target 以上架構不難 不過很容易把台灣的IXM ,HX,Delx Storage 工程師考倒 |
