Dell ConnectX-3 VPI HCA 8Kp6w

This Dell 8Kp6w is a ConnectX-3 VPI host channel adapter card. It delivers a single-port FDR14 InfiniBand connection at 56 Gb/s or 40/56 Gb/s Ethernet over a PCIe 3.0 x8 interface. The card uses one QSFP+ transceiver port and ships with a high-profile bracket.

Suits clusters needing FDR14 bandwidth

This adapter fits clusters and storage fabrics that require 56 Gb/s InfiniBand or 40/56 Gb/s Ethernet over a single QSFP+ link. It is not for systems that only offer PCIe 2.0 slots or lack a high-profile bracket clearance. Buyers who need dual-port density should select a different card.

Single-port QSFP+ at 56 Gb/s

The decisive specification is the single QSFP+ port operating at 56 Gb/s InfiniBand FDR14 or 40/56 Gb/s Ethernet. This port count and speed determine whether the adapter matches the fabric topology and uplink budget of the target cluster.

Highlights

  • Single-port FDR14 delivers 56 Gb/s InfiniBand throughput
  • PCIe 3.0 x8 host interface provides 40/56 Gb/s Ethernet connectivity
  • ConnectX-3 VPI CX353A controller supports HCRP and SPP protocols
  • High-profile bracket fits standard server chassis slots
  • QSFP+ transceiver port enables flexible optical or copper cabling

Questions about this item

What does 56 Gb/s mean for actual throughput on this adapter?

The single port runs at up to 56 Gb/s using FDR14 InfiniBand or 40/56 Gb/s Ethernet, limited by the PCIe 3.0 x8 host link.

How does the PCIe 3.0 x8 interface cap performance?

PCIe 3.0 x8 provides the host bandwidth ceiling for the 56 Gb/s port, so sustained throughput cannot exceed that lane budget.

What slot and bracket does this card need to fit?

It requires a PCIe 3.0 x8 slot and ships with a high-profile bracket for standard-height chassis.
