The Cosmos+ OpenSSD Platform is yet another PCIe-based SSD platform based on the HYU Tiger4 controller developed by ENC (Embedded and Network Computing) Lab. led by Prof. Yong Ho Song at Hanyang University, Korea. The HYU Tiger4 controller supports a subset of the NVMe interface protocol. In fact, the platform board is the same as the Cosmos Platform, but with a different storage controller (HYU Tiger4) in FPGA (you can upgrade the board by yourself). However, the Cosmos+ OpenSSD requires new memory modules (w/ toggle NANDs) because only the NAND flash devices with the toggle-mode interface are available.
