Overview
The Cisco UCS X440p PCIe node (UCSX-440P) is the first PCIe node that is part of the Cisco UCS X-Fabric
system.
The PCIe node pairs with Cisco UCS X-Series compute nodes and X-Fabric modules to support workloads
that require GPUs. The node is designed to work with its related hardware to simplify adding, removing, or
upgrading GPUs on compute nodes. For information about the hardware, see
The PCIe node supports PCIe connectivity for a variety of GPU form factors.
• GPUs:
• PCIe connectivity for either:
• Two x16 FHFL dual slot PCIe cards, one per riser cage
• Four x8 HHHL single slot PCIe card, two per riser cage
Each PCIe node must be configured with the same type of GPU. Per vendor
limitation, only the same GPUs are supported on a PCIe node,either two
A16, two A40, or two A100 GPUs in a PCIe node (Riser Type A), or four
T4 GPUs in a PCIe node (Riser Type B).
Note
• Host connection between the PCIe mezzanine (MEZZ) and the PCIe node is supported through a PCIe
Gen 4 (2 x16) connector in the rear MEZZ slot.
• Riser options, a maximum of two risers is supported in each PCIe node. Each riser type can contain a
specific type of GPU:
• Riser Type A supports 1x16 PCIe connectivity for FHFL GPUs
• Riser Type B supports 2x8 PCIe connectivity for HHHL GPUs
