PCIe BASED NETWORK ARCHITECTURES OVER OPTICAL FIBER LINKS: AN INSIGHT FROM THE ADVENT PROJECT
PCI Express based innovative architectures designed for datacentre connections are proposed exploiting fiber communications for remote very high speed connectivity. According with the ADVENT project approach a disruptive scenario based on an unique PCIe fabric is described, assuring convergent, storage/analytics functionalities mapped to a global shared memory. In particular, the hardware configuration of this kind of the proposed architecture is presented for inter host remote communications, showing the intrinsic advantages in terms of connectivity and applications. Moreover, experimentation of PCIe Gen3 interconnections over up to 2 km standard fiber is demonstrated strictly compliant with the standard.
