The system details:

Intel S5000 chipset
Areca 1260 with Battery.
10x Seagate 1TB disks.
Redundant 2+1 650 Watt Power supply.

The error comes when we transfer a lot of data. Open-E DSS abort the iscsi connection because my data is not reliable anymore.

I spat the error at Google and was provided with the following link:

There seems to be no final confirmation that the issue was related to vibration, but otoh there was no other response, either.

Probably some other tips mentioned in that thread (increasing time-outs etc) might help with your situation, too.
