Green PCB adapter with SlimSAS 4i and U.2 connectors plus two PCIe x4 slots

Innocard

Innocard SlimSAS 4i to PCIe x4 and U.2 to PCIe x4 Tri-Mode Adapter

SKU CH-KQ7J-MNYF3

Tri-mode adapter converts SlimSAS 4i and U.2 to dual PCIe x4 slots with 16GT/s Gen4 support, 6.5 A current limit and hot-plug power protection for Broadcom 95xx MegaRAID and HBA controllers

  • Changer TypePCIe Gen4
  • PCIe Gen4 16GT/s bandwidth for high-speed storage
  • Dual PCIe x4 slots from SlimSAS 4i and U.2 connectors
  • Broadcom 95xx tri-mode RAID and HBA compatibility
  • eFuse-protected 12 V hot-plug power with 6.5 A limit
  • SFF-8639 and SFF-8654 pin-outs per SFF-9402 1.1

Tri-Mode Adapter for MegaRAID & HBA

This Innocard adapter bridges SlimSAS 4i and U.2 connectors to dual PCIe x4 slots. It operates at PCIe Gen4 16GT/s and is designed for Broadcom 95xx series tri-mode storage adapters. The board includes active power management with eFuse protection on the 12 V rail and a synchronous buck converter for 3.3 V delivery. It is built in Taiwan.

Check Motherboard Slots and Backplane Pin-Outs

Verify that the host system provides two physical PCIe x4 slots with electrical x4 links. Confirm the backplane uses SFF-8654 4i pin-out per SFF-9402 Rev 1.1 and that BP_TYPEA or BP_TYPEB pull-ups match the Broadcom 95xx requirement. Ensure the chassis can supply 12 V hot-plug power within the 6.5 A programmable current limit. The adapter also requires SMBus two-wire buffer support for hot-swap signalling.

Replaces Separate U.2 and SlimSAS Carrier Boards

This single card consolidates U.2 (SFF-8639) and SlimSAS 4i (SFF-8654) breakout functions that would otherwise need two adapters. The jump is worth it when deploying Broadcom 95xx PCIe 4.0 MegaRAID or HBA tri-mode controllers that demand both CPRSNTA# and CPRSNTB# pull-low detection. It also eliminates the need for discrete 12 V to 3.3 V conversion modules and external eFuse circuitry.

Highlights

Questions about this item

Does the adapter include cables or do I need to buy SlimSAS 4i and U.2 cables separately?

The adapter provides the SFF-8654 4i and SFF-8639 connectors on-board; SlimSAS 4i and U.2 cables are not included and must be purchased separately.

Which Broadcom controller generations does this adapter support for Tri-Mode operation?

It is designed for Broadcom 95xx PCIe 4.0 MegaRAID and HBA Tri-Mode storage adapters using the BP_TYPE and CPRSNT pull-up/pull-low signals.

What does the PCIe Gen4 16GT/s rating mean for drive performance in a live server?

The x4 slot delivers up to 16 GT/s per lane, allowing each connected U.2 or SlimSAS 4i drive to run at full PCIe 4.0 x4 bandwidth without host-side bottlenecks.
