Cubix Xpander Fiber 8 5U Rackmount PCIe Expansion Enclosure with Redundant Power Supply

Xpander Fiber 8 with Redundant Power (RP) supplies is a 5U rack mount PCI Express (PCIe) expansion enclosure that enables fiber-optic connection of 8 double-wide accelerators to a host computer. Xpander Fiber 8 (XF8) supports accelerators like graphical processing units (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 available for the fiber-optic host interface controller (HIC).

XF8 provides one Main Interface Board (MIB) connected via fiber-optic cables to a HIC in a host computer. One pair of fiber-optic cables support a x8 connection or two pair of fiber-optic cables support a x16 connection. The MIB in Xpander features eight PCIe x16 slots that support eight double-wide GPUs with active cooling such as NVIDIA Quadro or GeForce GTX Series, AMD FirePro W9100 Series or Intel Xeon Phi. XF8 provides one set of eight PCIe x16 slots for GPUs for use with post-production applications such as Blackmagic Design DaVinci Resolve.

With 8 x Intel Xeon Phi processors, XF8 supports parallel processing applications. Cubix designed XF8 with a single main board specifically for applications like AI that require the fastest peer-to-peer (P2P) transfer rates possible. For example, Cubix has measured P2P transfer rates of 12.5GBytes/second simultaneously in both directions among 8 x NVIDIA GPUs.
