Innocard PCIe 4.0 SlimSAS 8i x2 to Gen-Z 1C 4-port Adapter

SKU CH-C6K8-F58H7

Converts two SlimSAS 8i ports to four Gen-Z 1C ports with 12 V hot-plug power, eFuse protection and Broadcom 95xx tri-mode support

  • Adapter typePCIe Gen4
  • PCIe 4.0 SlimSAS 8i x2 interface enables high-speed connectivity to Gen-Z 1C storage
  • Four Gen-Z 1C ports with individual 12 V eFuse protection and 6.5 A current limit
  • Hot-plug power with thermal shutdown and fault alert safeguards each connected device
  • SMBus hot-swap buffers and side-band signal support ensure reliable drive insertion and removal
  • Green and red LEDs per port give immediate visual status of power and activity

Broadcom 95xx Tri-Mode Adapter Link

This adapter connects Broadcom 95xx PCIe 4.0 MegaRAID and HBA Tri-Mode storage controllers to Gen-Z 1C devices using two SlimSAS 8i ports. It is built for integrators and system builders who need to bridge these specific controller families with Gen-Z 1C storage enclosures or backplanes. The card converts the SFF-8654 interface to four Gen-Z 1C ports in a single bracket.

Hot-Plug Power and Signal Integrity

Each of the four Gen-Z 1C connectors includes dedicated 12 V hot-plug power circuitry with eFuse protection and a programmable 6.5 A current limit. An SMBus hot-swappable two-wire buffer manages side-band signals such as CLKREQ#, WAKE#, PWRBRK#, PWRDIS and SMBRST#. Green LEDs show power-ready status while red LEDs blink to indicate active links, giving immediate visual feedback during drive swaps.

Verify Controller and Backplane Pin-Outs

Confirm the host adapter is a Broadcom 95xx series Tri-Mode card that supports the required BP_TYPE and CPRSNT pull-up and pull-down configurations defined by SFF-9402 Rev 1.1. Ensure the target backplane or enclosure uses Gen-Z 1C connectors compatible with the adapter's pin-out and that the chassis can supply 12 V power to the card's onboard hot-plug circuitry.

Questions about this item

What PCIe generation does the SlimSAS 8i interface run at, and what bandwidth ceiling does that impose?

The adapter is compliant with the PCI Express Base Specification Rev 4.0, so each SlimSAS 8i link operates at Gen 4.0 speeds, capping throughput at the PCIe 4.0 lane rate.

What physical connectors and slot width does this card need to fit in a server chassis?

It requires two SFF-8654 8i SlimSAS receptacles and four Gen-Z 1C ports, occupying a standard PCIe add-in card bracket; no extra drive-bay or backplane cut-outs are mentioned.

How is the adapter installed, and which step do installers most often miss?

Seat the card in a PCIe 4.0 slot, attach the two SlimSAS 8i cables to the Broadcom 95xx MegaRAID or HBA Tri-Mode adapter, then connect Gen-Z 1C devices; the step most often missed is enabling the CPRSNTA# and CPRSNTB# pull-low signals so the Broadcom controller detects the link.
