Abstract
Embodiments of the present invention provide a hybrid system architecture random access memory (RAM) such as Phase-Change RAM (PRAM), Magnetoresistive RAM (MRAM) and/or Ferroelectric RAM (FRAM). Specifically, embodiments of this invention provide a hybrid RAID controller coupled to a system control board. Coupled to the hybrid RAID controller are a DDR RAID controller, a RAM RAID controller, and a HDD/Flash RAID controller. A DDR RAID control block is coupled to the DDR RAID controller and includes (among other things) a set of DDR memory disks. Further, a RAM control block is coupled to the RAM RAID controller and includes a set of RAM SSDs. Still yet, a HDD RAID control block is coupled to the HDD/Flash RAID controller and includes a set of HDD/Flash SSD Units.
