Ata raid

This technology is made possible with a combination of firmware and software. The operating system can be installed on a preconfigured mirror RAID 1 volume. Regardless of which drive fails, recovery of the ata raid after replacing the drive does not require user or operating system intervention, ata raid.

Supporting RAID levels 0, 1, 5, 10, 50 and JBOD, plus disk hot plug and Adaptec advanced RAID features, the Adaptec SA is an ideal cost-effective solution for applications where high levels of sustained read and write performance are required, including video streaming, web content, reference data and fixed content storage. Optimized Disk Utilization , exclusive to Adaptec, enables the Adaptec SA to utilize the full available capacity of all attached drives, even if drive sizes are different. This avoids wasted drive capacity and provides advantages over competing cards that limit capacity usage to the smallest drive in an array. Online Capacity Expansion enables IT managers to create multiple arrays across a single set of drives connected to the Adaptec SA, so that specific arrays can be optimally tuned to meet the differing needs of multiple applications. Adaptec's RAID Level Migration feature means that data protection and system performance levels can be simply set and changed by users in order to meet the changing demands of their business.

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.

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 :.

In addition, you cannot change the stripe size of an array that has already been configured. Under a RAID 1 setup, an extra drive called as the spare drive can be attached.
