Re: DL 380 G5 RAID 5 Slow
and what about juan quesada suggestion
" As a workaround:
The write caching can be disabled by setting the Read/Write ratio to 100/0 on the logical drive being utilized"
did you give it a try?

Re: DL 380 G5 RAID 5 Slow
Many thanks
The server has just rebooted though unexpectedly so I am now thinking of rolling back to the original version of the driver if its a driver issue.
I will keep you informed.
Thanks again

Re: DL 380 G5 RAID 5 Slow
More investigation seems to point to the TCP Offload Engine. I have now done the following:
Run:
netsh int ip set chimney disabled
I have Disabled Receive-Side Scaling, TCP Offload Engine all under the teaming on the server. I have installed the latest drivers for the NIC's and the teaming software. Deleted the TEAM and recreated it. Rebooted after all these changes. I have made sure that the Switch is set to AUTO/AUTO and that the NIC's are also set to AUTO/AUTO.
I am running out of ideas. Searching the forum as found some help as I have gone through everything in the post:
http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1158952&admit=109447626+1204648547079+28353475
But I am still having the same errors.
Anymore suggestions greatly appreciated.

SolutionWhen you try to update the driver it will not overwrite the existing one, so, what we do is actually delete the driver from windows registry and we installed manually. This way it will work
Solution.
Download the driver for your OS version on a USB Key, save the driver into a temporary folder in the affected server, make sure that the folder and its contents are not marked as read only.
1) Go to the device manager and right click on the NIC device and select Uninstall
2) Go to Start > Programs > Accesories > System Tools > System Information.
3) On the left side click on the + sign to expand the menu > Click on the + sign to expand Network menu > click on adapter.
4) On the right page look for the HP NC31xx Fast Ethernet NIC Driver location. Copy the driver location and then go to the folder where the driver resides and manually delete it.
5) Reboot the server and stop windows driver installation. If it prompts for you to choose the new driver cancel all request and get into windows, once there install the driver from the .exe file that you downloaded.
6) Reboot the server. By now you should be able to use the NIC card.

Re: DL 380 G5 RAID 5 Slow
Driver Name BXND52X.SYS
Driver Version 4.1.3.0
VDB Driver Version 4.1.5.0
Bootcode Version 1.9.6
Teaming is set to 9.0.0.0
There are now no packets being dropped. However to speed is still really slow:
When saving a word file to a DL380 G4 it takes 1 second. Saving the same file to a DL 380 G5 takes 15 seconds.
Any suggestions are greatly appreciated.
Thanks
Chris

Re: DL 380 G5 RAID 5 Slow
I have changed the settings on the pc's NIC to none for the Checksum offload and disable for the Large Checksum offload
With this done we get a throughput of on the Team Utilisation:
575Mbps on the RX
261Mbps on the TX
This is a vast improvement.
However, on the production server if I run this test I can get the speed up to 520Mbps on the RX and 227Mbps on the TX at its peek but the average is 163Mbps on the RX and 112Mbps on the TX.
I have updated to the latest SSD's too version 8.0
Thanks again for any suggestions.

Re: DL 380 G5 RAID 5 Slow
Sometimes I have found that simply having the firmware up-to-date takes care of a lot of the problems that happen like this.
