Hi, I have done pNFS setup with single Dataserver and Two Dataserver and ran the IOzone tool on both, I found that the performance with multiple dataservers is less than the performance with single dataservers. Here are some numbers, which were captured by the IOzone tool. 4 8 16 32 64 128 256 512 1024 <== Record Length in KB With Single Dataserver: Read operation for file size 1 MB- 66415 66359 63630 70358 86223 70256 66047 66068 68489 <== IO kB/sec Write operation for file size 1 MB- 18827 16920 18846 17039 18896 17009 17173 19206 17947 <== IO kB/sec With Two Dataservers : Read operation for file size 1 MB- 36882 381198 38150 38084 38749 33663 34398 37313 37847 <== IO kB/sec Write operation for file size 1 MB- 5461 4661 5586 4870 5227 4922 4214 5572 4658 <== IO kB/sec Can somebody tell me What could be the issue.... -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
