thanks for a contact to someone technical in Areca support, or Areca itself, but as I expect he write a driver but he don't fully realize the problem and dont have any hardware and resources/knowledge to understand the problem that's something not right on the driver and/or firmware of areca when working on vmware, same areca working quite ok when we use it in a NAS (on Solaris based NAS server) without any kernel panic's and problem with occupation one raid set and don't have normal access to other raid sets on the controller.
the psods have gone when I change driver to default or to little older one, i'm not sure where are a differences because Areca have strange naming and numerring of a drivers scheme but it working quite ok under vmware (only with one raid set) besides long latency during high load and then very low performance, but much better solution is to use it in a NAS/SAN server and then serve it to vmware, Areca just in my opinion dosnt have good drivers and firmware and support for vmware environment.

thanks for info, it may be helpfull but I decide to move areca and hdd/sdd to a NAS server and now its working quite ok (and really fast).
