INTERFACE SPECIFICATIONS

SSD OPERATION

The ZeusIOPS Fibre Channel SSD is comprised of the following primary functional blocks: the SCA- 2 interface connector, a Host FPGA, which contains a processor, NAND FPGA, NAND flash memory, and DRAM.

Read/write data transfer requests are initiated by the host via the SCSI bus interface. Once received, the Host FPGA controller, under the direction of the microcontroller, processes the request.

The FPGA NAND flash controller interfaces with the NAND flash chips and sequences the data flow between the DRAM and flash.

It is the microcontroller that will initiate and monitor all activity within the controller, including the execution of the bad-block mapping and wear-leveling algorithms.

The controller will decode an incoming host command, and will configure the appropriate interrupts and status for the local microprocessor to handle various SCSI commands. For read and write transfer commands, there are hardware functions that minimize firmware overhead to enhance performance.

Read and Write commands have dedicated hardware functions that do not require firmware support, thereby increasing performance. Some commands may require the host controller to use external circuitry that do not involve the flash memory controller.

When a Read or Write operation is requested, the integrated DMA controllers transfer the Fibre Channel frames to and from the SSD DRAM.
