I had been in contact with Atto Support for about one month.
I made several test with different cables, hard drives, a different graphic card (Nvidia Quadro FX4800 for Mac instead of Ati 4870), different raid settings.
No way.
Finally I sent back Atto R380 to Technical Support.
Now I’m waiting to know the response.
Actually I don’t know if it was an R380 hardware issue, a MacPro hardware issue or something different.
Please, let me know if your configuration will work.
