Connections
On the rear panel, HostEngine provides USB 3 ports, Gbps Ethernet ports, a VGA port and HD
audio ports. The AC power receptacle is also on the rear panel.
HostEngine also provides access for Cubix HICs that connect to GPU-Xpander Rackmount 8 or
other Xpander enclosures using external PCIe x16 cables, if needed. With these connections,
you can mount HostEngine immediately above or below GPU-Xpander Rackmount 8. You can
also install PCIe cards inside HostEngine 4U. For example, install 4 x full-length, full-height,
double-wide GPUs inside HostEngine 4U.
On the front panel, HostEngine provides 2 x local USB ports.
Troubleshooting Procedure
Issue:
The Cubix HIC in HostEngine is linking at x8 or x4, or at Gen 2, with Cubix
Xpander, and not linking at the specified PCIE Gen 3 x16 transfer rate.
Resolution:
Confirm that the Cubix HIC is installed in HostEngine slot 1, 2, 3 or 5.
Issue:
The Cubix HICs in HostEngine are installed in PCIE Gen 3 x16 slots 1 & 3 or 2 &
5, but not all 8 x GPUs in Xpander Rackmount 8 show up in the operating system
(ls pci in Linux or Windows Device Manager > Display adapters).
