RAID 5 v 10
After experiancing write queing on some production sql servers using raid5, I decided to test raid10, so I setup two identical DL380's with 6i controller one with a raid10 array for the sql data and the other with raid5.
The test was to perform a simple insert 100,000 times.
This took 6mins on both servers, exactally the same time.
Shouldn't the RAID10 have written a lot faster?
Thanks
Rich

Re: RAID 5 v 10
You might want to take a look at this pages, on Raid 10 it specifies:
"All drives must move in parallel to proper track lowering sustained performance"

Re: RAID 5 v 10
That is, run specific disk intensive writes without other application running, to discard other variables. RAID 10 should be faster.
For disk and file system performance tools see:

Re: RAID 5 v 10
Thanks for the links. I will check them out.
In the mean time, I forgot to mention I was running perfmon and on both tests the Avg Disk Write Queue was upto the 100's and processor, paging etc was pratically none.

Re: RAID 5 v 10
Would a longer test or larger insert be a better test. i.e. fill the cache.
Then the faster RAID10 should show its advantage?
I feel I am missing something, as it is widely talked about that RAID10 should give significant performance advantahes over 5!
Cheers
