4.3. DFC Implementation
This version of OX runs in the DFC and any other ARM or x86 platforms. The communication with hosts are done via NVMe over Fabrics. We have implemented a full-fledged FTL called OX-Block that is available in OX 2.6 release.
We have implemented a PCIe interconnection handler, a media manager to expose 8 channels, NVMe and LightNVM support. The DFC-based OX controller is a layered architecture that enables future extensions such as support for other devices and Fabrics/RDMA interconnection.
OX v1.4 does not have a FTL for the standard Block I/O interface. For using OX-Block as block device FTL, please refer to OX v2.x.
Table 3 shows the latest DFC stable firmware tested with OX 1.4. Please be sure of your FPGA version. OX is current implemented for FPGA 03.01.00.
