An apparatus generally having a plurality of disk drives and a controller is disclosed. Each of the disk drives may have a first region and a second region. The first regions may have a performance parameter faster than the second regions. The controller may be configured to (i) write a plurality of data items in the first regions and (ii) write a plurality of fault tolerance items for the data items in the second regions.

High performance raid mapping

A system and method for handling shared resource writes arriving via non-maskable interrupts in single thread non-mission critical system with limited memory space includes a queue for providing temporary storage of a write request. The queue is accessible by lower or higher priority processes for the servicing of the write requests. Upon completion of service to the write requests the system returns control to the standard operations of the single thread system.

System and method for handling shared resource writes arriving via non-maskable interrupts (NMI) in single thread non-mission critical systems with limited memory space

An apparatus comprising one or more drive portions and a controller. The one or more drive portions may each comprise one or more drives. The controller may be configured to map correctly correlating addresses to the one or more drives.
