Xpander Rack Mount 8 4U
Gen 3 User Guide
Xpander Rack Mount 8 4U is a rack mount PCI Express (PCIe) expansion enclosure that
enables connection of 8 double-wide graphics or other controllers with rear-connected auxiliary
power cables to a host computer. Rack Mount 8 4U also supports GPUs with passive cooling.
The host must have at least one PCIe x16 slot available for each host interface controller (HIC).
Rack Mount 8 provides two Main Interface Boards (MIBs) connected to each of one or two host
computers with a PCIe x16 cable and four PCIe x16 slots for a total of eight double-wide GPUs
like NVIDIA Quadro or Tesla Series, or Intel Xeon Phi Coprocessors. Each MIB connects via a
PCIe x16 cable to a HIC in a host computer. Connect each MIB to one of two HICs in one host
or each MIB to a HIC in each of two host computers. Each MIB inside Rack Mount 8 connects to
one host computer.
One host computer can support both MIBs inside the Rack Mount 8 enclosure if the host has
two available PCIe x16 slots. Each MIB inside the Rack Mount 8 enclosure connects to one
HIC. Rack Mount 8 provides two
sets of four PCIe x16 slots for
graphical processing units
(GPUs), which you can use for
graphical rendering, for high-
performance computing (HPC)
and other Compute Unified
Device Architecture (CUDA) -
enabled tasks. Rack Mount 8 can
also support other PCIe adapters
with multiple Input / Output (IO)
ports such as FireWire, USB 3.0
or high-definition (HD) audio. See
examples of configuration options
at the right.
