The advantage of an Array is to provide better performance or data fault tolerance. Fault tolerance is archived through data redundant operation, where if one drives fails, a mirrored copy of the data can be found on another drive. This can prevent data loss if the operating system fails or hangs. The individual disk drives in an array are called «members». The configuration information of each member is recorded in the «reserved sector» that identifies the drive as a member. All disk members in a formed disk array are recognized as a single physical drive to the operating system. If any disk member fails, it affects the entire array.

Connect and share knowledge within a single location that is structured and easy to search. Running the command omreport chassis biossetup on the server shows me the following configuration setting:. I've been looking online to find out what this setting means and what the various options refer to but I've been unable to find anything particularly helpful, so I was hoping that somebody here could help to enlighten me. Off - disables the embedded controller. Should be pretty obvious what happens here. Basically, sets the controller to act like a regular ATA controller. A driver must be installed to use QDMA mode. Using this mode, you'll likely need to inject a driver during your install sequence to recognize any devices connected to the controller. Would allow you to setup RAID levels across multiple devices connected to the controller. So, lets move on and tackle your actual problem: What kind of disk performance are you seeing and what kind of disk performance are you expecting to see?

A disk array controller is a device that manages the physical disk drives and presents them to the computer as logical units. It also often provides additional disk cache. Disk array controller is often ambiguously shortened to disk controller which can also refer to the circuitry responsible for managing internal disk drive operations. A single controller may use different protocols for back-end and for front-end communication. In a modern enterprise architecture disk array controllers sometimes also called storage processors , or SPs [1] are parts of physically independent enclosures , such as disk arrays placed in a storage area network SAN or network-attached storage NAS servers. Those external disk arrays are usually purchased as an integrated subsystem of RAID controllers, disk drives, power supplies, and management software. It is up to controllers to provide advanced functionality various vendors name these differently :. A simple disk array controller may fit inside a computer, either as a PCI expansion card or just built onto a motherboard.

RAID 0 does not support fault tolerance. Software RAID will not allow you to set up a RAID 0 configuration on the operating system volume because it will not allow the operating system to be distributed across drives.
