Innocard PCIe Gen4 SlimSAS 8i ReDriver for EPYC 7002

SKU CH-BDKG-1KF8E

A PCIe 4.0 ReDriver board with SlimSAS 8i connector extends 16 GT/s signals over longer cables for EPYC 7002 systems

  • Changer TypePCIe Gen4
  • PCIe 4.0 x8 at 16 GT/s for EPYC 7002 series
  • Built-in ReDriver extends Gen4 8-lane signals over longer cables
  • On-board 100 MHz clock buffer drives extended trace lengths
  • SFF-8654 SlimSAS 8i pin-out follows SFF-9402 Rev 1.1 spec
  • Multiple bus buffers support PERST#, WAKE#, CLKREQ# and PWRBRK# lines

EPYC 7002 PCIe Gen4 Adapter

This adapter converts a PCI Express 4.0 x8 slot into a SlimSAS 8i interface for AMD EPYC 7002 series platforms. It targets system integrators and server builders who need to extend high-speed connectivity to backplanes or storage enclosures using the SFF-8654 connector standard.

SFF-8654 Pin-out and Signal Limits

The onboard SFF-8654 8i connector follows the SFF-9402 Rev 1.1 pin-out definition. A built-in PCIe ReDriver extends the 16GT/s differential signals across eight lanes, while integrated clock, sideband and power-break buffers maintain link integrity over longer trace lengths and cable runs.

ReDriver for Extended Reach

The specification that determines suitability is the integrated PCIe Gen4 ReDriver, which regenerates 16GT/s signals to support longer cables than a passive adapter allows. Buyers who need a simple passive gender changer without signal conditioning should choose a different part.

Highlights

  • PCIe 4.0 x8 at 16 GT/s for EPYC 7002 series

Questions about this item

Should I choose the x8 or x16 version for my EPYC 7002 build?

The adapter provides a PCIe x8 Gen 4 link at 16 GT/s, so select the x8 version to match this lane count.

What does 16 GT/s mean once the card is installed?

It delivers 16 GT/s across eight lanes through the ReDriver, sustaining Gen 4 bandwidth over longer SlimSAS cables.

Does the SlimSAS 8i connector follow SFF-9402 Rev 1.1 pin-out?

Yes, the built-in SFF-8654 8i connector uses the SFF-9402 Rev 1.1 pin-out for PCIe 4.0 cabling.
