Read or write in DSS7 < 2Mbps

Hi,

Sometimes, we have a low flow for access to our DSS7.
After reading log, i found these errors :

Code:

Have you an idea to prevent this slowing down ?
Thank you for your help.

Was it always slow when you first tested or did this just started to be slow? There are many types of call trace errors, what your showing can point out to be IRQ hogging and you might want to remove any power management from the BIOS of the motherboard. Check that the firmware is updated on the RAID controller and the motherboard. Check to see if the RAID controller is not in a Write Thru state or that it is charging the built in battery device or doing a rebuild from a failed drive.

Hi,

Thank you for your answer.
Before answer, each week we must reboot NAS because its performance is slowed.
I could view these error after reboot NAS (3 hours), but it was always slow after shutdown...

I will update firmware to 7.0up12 (actually 7.0up11).
Is-it possible in your interface to see bandwidth and W/R to each user ?

Thank you.
Regards,
Charlie.

In the Console screen in CTRL ALT N then select the NIC and look in the Info section you will see speed and other information for the RX and TX values as well. For the users you will need to see from there systems there speed.
