The IntelliProp IPC-BL109A-RD SATA RAID Core is a hardware design block written in HDL that performs RAID 0 operations to provide higher performance access to storage endpoints.
RAID 0 will divide data among multiple storage endpoints providing higher system storage performance.
- Striping (RAID 0) splits the data across multiple endpoints for greater performance.
- Capacity (RAID 0) combines the capacity of all the endpoints using concatenated mode or RAID 0 mode.
The IntelliProp RAID IP Core introduces very little latency to issue commands and to transfer data between the SATA storage devices and the backend data interface. The RAID IP Core is designed to exist within a customer’s larger design to provide RAID performance availability and capacity advantages.

Functional Description
The hierarchy of the RAID design can be divided into 2 main blocks:
- SATA Host Cores
- RAID Engine
The SATA interface to each drive is implemented with the IntelliProp SATA core configured as a SATA host.
The RAID Engine consists of an LBA/Sector Count translator, a data router (FIFO to FIFO XFER) and a RAID State Machine. Customer interface to the RAID core is similar to the application layer interface of the SATA core. The data is exchanged through a FIFO and control is completed through some simple registers for processor connections or wires for state machine connections.
