eshinreal PCIe 4.0 x16 to 2x SlimSAS 8i SFF-8654 Active Retimer Expansion Card

SKU CH-GZPD-HDJ7G

Adds dual SlimSAS SFF-8654 8i ports over a PCIe 4.0 x16 link with active retiming for extended NVMe and SAS cable runs

  • Product typeController Card
  • PCIe 4.0 x16 provides 64Gbps total bandwidth for storage arrays
  • Dual SFF-8654 8i ports connect 16 lanes to NVMe SAS SATA devices
  • Active retimer extends cable reach beyond 5m while preserving signal integrity
  • Non-bifurcated design works in any standard PCIe slot without motherboard splitting
  • Enterprise cooling and hot-plug support enable reliable rack deployment

PCIe 4.0 x16 Retimer Card

This add-on card uses a PCIe 4.0 x16 interface to provide dual SlimSAS SFF-8654 8i ports for high-speed storage expansion. It is built for enterprise and data-centre workloads that need reliable, long-distance connections to NVMe and SAS arrays while maintaining full bandwidth.

Installation and Common Issues

The non-bifurcated design lets the card function in any standard PCIe x16 slot without motherboard lane-splitting support. An 8-pin auxiliary power connector must be attached, and the included brackets allow tool-less switching between full-height and low-profile form factors.

Pre-Order Compatibility Check

Verify that your system has a free PCIe 4.0 x16 slot and an available 8-pin power cable from the power supply. Confirm that your target storage devices or backplanes use SFF-8654 8i connectors and that your operating environment stays within the 0°C to 85°C operating range.

Questions about this item

How can I confirm the active retimer is maintaining PCIe 4.0 x16 link speed after installation?

Verify the system reports a 16 GT/s per lane link across all 16 lanes and check that the port status LEDs on the bracket show solid green for each active SFF-8654 8i connection.

What ships with the card and which cables or drives must be purchased separately?

The box contains the retimer adapter, a full-height bracket, a low-profile bracket, and an 8-pin auxiliary power cable; SlimSAS SFF-8654 cables and any NVMe, SAS, or SATA drives are sold separately.

Which version should I choose for a 24G SAS array versus an NVMe 1.4 U.2 deployment?

The same dual-port card handles both; it supports SAS 24G with compatible expanders and NVMe 1.4 U.2/U.3 directly, so select based on the total lane count and cable length you need.
