The Cubix Xpander Fiber 8 4 RU Rackmount PCIe Expansion Enclosure enables fiber-optic connection of eight double-wide accelerators to a host computer. It supports accelerators like GPUs or Intel Xeon Phi processors with passive cooling and rear-connected auxiliary power cables. The host computer must provide one PCIe Gen 3.0 x16 slot for the fiber-optic host interface controller (HIC).
The XF8 provides one MIB (Main Interface Board) connected via fiber-optic cables to a HIC in a host computer. One pair of fiber-optic cables support an x8 connection or two pair of fiber-optic cables support an x16 connection. The MIB in Xpander features eight PCIe x16 slots that support eight double-wide GPUs like NVIDIA Tesla Series, AMD FirePro 9000 Series, or Intel Xeon Phi.
The XF8 provides one set of eight PCIe x16 slots for GPUs for use with HPC (High-performance Computing) such as AI (artificial-intelligence) or deep-learning and other CUDA (Compute Unified Device Architecture) applications like AMBER. With 8 x Intel Xeon Phi processors, XF8 supports parallel processing applications. The XF8 is designed with a single board specifically for applications like AI that require the fastest peer-to-peer (P2P) transfer rates possible.
