XY77D-B7109 is the fifth generation of Tyan's 4U 8GPU server platform based on the new Intel Xeon Scalable Processor Family. It builds upon the success of previous generations by adding additional features that our customers have asked for over the years. These enhancements include support for an internal storage mezzanine slot, allowing the deployment of SAS drives without consuming precious PCIe slots in the rear that would otherwise be used by GPU cards. Engineers also found additional space next to the 8 GPU cards in the server for a 9th PCIe x16 slot, ideal for high speed networking or NVMe retimer deployment.

As a dual root complex GPU server, the B7109 deploys a pair of Xeon Scalable Processors with an even split of GPU cards between the two. The motherboard deploys a set of four PLX PEX8747 PCIe switch chips to provide the connectivity for the 8 GPU card slots. The B7109F77DV14HR-2T-NF SKU adds support for Xeon processors with integrated Intel Omni-Path 100 gigabit networking fabric.
