Innocard GD0804A PCIe Gen4 SlimSAS 4i U.2 Adapter with Hot Plug Power protection

Innocard GD0804A Adapter Purpose

The Innocard GD0804A is a PCIe Gen4 adapter that converts a U.2 SFF-8639 connection and a SlimSAS 4i SFF-8654 connection each to a PCIe x4 slot. It is built for system integrators who need to attach enterprise U.2 or SlimSAS 4i storage devices to a standard PCIe x4 interface while keeping the link at Gen4 16GT/s speeds.

Target Builder and Limits

This adapter suits builders who require hot-plug capability with integrated eFuse protection on the 12V rail and a programmable 6.5A current limit for safe device insertion. It also provides SMBus buffering and specific pull-up or pull-down support for Broadcom 95xx Tri-Mode RAID or HBA controllers. Buyers needing a different connector family or lacking a PCIe x4 host slot should look elsewhere.

Deciding Specification

The single specification that decides fit is the dual-converter layout: one SFF-8639 U.2 port and one SFF-8654 SlimSAS 4i port, each wired to its own PCIe x4 slot under the SFF-9402 Rev1.1 pin-out. If the build calls for exactly those two source connectors feeding two separate x4 slots, this is the correct part; otherwise it is not.
