Dell Perc 6/i RAID5 測試
最近買了一張Dell Perc 6/i
用四顆Barracuda 11 500G組RAID5 write-through / read ahead 但是做了測試感覺數據怪怪的 都停在100左右  把read ahead關掉可以到120左右 不知道大家有什麼想法嗎？  CPU: E6750 MOBO: G33M-DS2R RAID Installed on PCI-E 16x 2x 250G Barracuda 10 RAID1 @ CH0 on Perc 6/i 4x 500G Barracuda 11 RAID5 @ CH1 on Perc 6/i

看要不要先跑RAID0試試看PCI-E頻寬，
如果RAID0可以正常的發揮出RAID0的頻寬， 那可能是卡的問題(BIOS或是驅動程式還沒有到最佳化)； 如果RAID0頻寬一樣上不去的話， 例如兩顆RAID0的傳輸速率沒有到單顆8成效率的兩倍， 那麼可能是這張卡在這張版子上無法發揮全速， 就需要換一張主機板測試看看。

看到這個access time 實在很好奇您的stripe size設多大呢 此外 您的傳輸速度讓人感覺頻寬好像被限制住了 要不要查一下 pcie目前試跑幾倍呢？？ 另補上小弟先前做的測試 raid5 test with 3*wd 500aaks disks on perc5i : WriteBack Consist checking http://www.imagepile.net/index.php?...%20checking.jpg raid5 test with 3*wd 500aaks disks on perc5i : WriteThrough Consist checking http://www.imagepile.net/index.php?...%20checking.jpg 由於剛好在做一致性檢查 所以傳輸速度大約減半 給您作個參考 此文章於 2008-04-30 07:23 PM 被 八尾半 編輯. |

我用Everest看了一下
PCI-E是跑在8X沒錯 Stripe Size 128KB Barracuda 11 500GBx4  第一張貼的是Always Read Ahead 下面貼兩張其他的讀取方式 Adaptive Read Ahead  No Read Ahead  附上一張MegaRaid StorageManager的圖

補上CrystalMark
一樣是Adaptive Read Ahead
128KB Stripe Size Write-Back 用CrystalMark 2.1.4 X64版本 這張是我Barracuda 11 500Gx4 @ RAID5  下面這張是我的Barracuda 10 250Gx2 (單碟) @ RAID1 (後段160GB)  感覺數據不太真實

建議 用 32K or 64K
128K 太大了.... 請看這篇 http://www.pcdvd.com.tw/showthread.php?t=719297 當初 軟體XOR , 32K , 64K , 128K , 影響很多..... |

我覺得CrystalMark的數據是直接從我卡上的RAM得到的傳輸率吧 剛剛試了一下Everest Disk Benchmark (Read Suite Test)  這個數據正常多了
