MSA30 and 6404 Speed issue
both MSA30's are fully populated with 14 15k u320 drives.
The Operating system is WIN2003 64bit.
All updates have been applied.
Here is things I have checked.
Cables are properly connected.
All drives are 15k U320.
6404 is U320 capiable I think.
One MSA30 is connected to the 6402 part of the controller and the other MSA30 is connected to the EM.
Both MSA 30 are DB and have both cables connected.
HP insight shows no problems.
Here is the Problem:
I have tested both MSA30's are am getting only 124 MB average read. with a max burst of 181MB. According to most references that I have come accross it should be atleast 320MB.
Please Help me resolve this problem.
Thanks,
Scott

Re: MSA30 and 6404 Speed issue
1024k read size 61MB/S
512k read size 61MB/S
256k read size 61MB/S
16k read size 61MB/s
Here are some interest facts that I noticed
The disk que was fairly constant at around 7.1
I find it strange that the exact same read size yielded the same performance.
