The slot shouldn't cause a kernel panic. &nbsp;If you are running latest BIOS on the controller &amp;&nbsp;drivers, then call Atto. &nbsp;This is a firmware/driver bug

Hi<br />
Thought as much, I actually think it's to do with the RAID. It will not mount at all or even show in disk utility although the ATTO configuration app does show the card is present and the the Infortrend unit is recognised.<br />
I have also stuck an LSI card in a PC and configured to see if will show a volume but nothing!<br />
<br />
I have since deleted the LUN mapping and logical drive setup on the infortrend and in the process of creating a new RAID 5 configuration.

I would stick the Atto in a windows or LINUX PC and configure it there first.

Right, the infortrend is on it's own and will continue the rebuild

Hi<br />
Could anyone tell me if this port is the best port to install and ATTO ExpressSAS H680 card or doesn't it matter?<br />
I've had it installed in port 3 but for some reason when I attach an infortrend storage unit (with a 22tb RAID 5 configured) the volumes either do not mount or I get a kernal panic.<br />
<br />
Thanks

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

RAID stands for Redundant Array of Independent Disks.

RAID is data storage technology that allows multiple drives to be used together as a single virtual drive for reasons such as fault tolerance, reliability and performance. 

There are several different levels of RAID that determine how the data is stored and the level of redundancy achieved across the drives.
