PCIe slots
⚫
I/O module 1 provides slots 1, 2, and 3. If a two-slot PCIe riser module is used, slot 1 is
unavailable. If a module with 2 x 2.5" drives and one PCIe card is used, slots 1 and 2 are
unavailable.
⚫
I/O module 2 provides slots 4, 5, and 6. If a two-slot PCIe riser module is used, slot 4 is
unavailable. If a module with 2 x 2.5" drives and one PCIe card is used, slots 4 and 5 are
unavailable.
⚫
I/O module 3 provides slots 7 and 8. If a one-slot PCIe riser module is used, slot 7 is
unavailable.
Observe the following rules when configuring GPU cards:
⚫
When one to five x16 T4 GPU cards are configured:
⚫
I/O module 1 supports two HHHL PCIe x16 GPU cards.
⚫
I/O module 2 supports two HHHL PCIe x16 GPU cards.
⚫
I/O module 3 supports one HHHL PCIe x16 GPU card (in slot 8).
⚫
When six to eight T4 GPU cards (six x8 + two x16) are configured:
⚫
I/O module 1 supports two HHHL PCIe x8 and one HHHL x16 GPU cards.
⚫
I/O module 2 supports two HHHL PCIe x8 and one HHHL x16 GPU cards.
⚫
I/O module 3 supports two HHHL PCIe x8 GPU card.
PCIe Riser Modules
