SlimSAS SFF-8654 8i cable, 0.75 to .8m, 74-pin connectors, 85-ohm impedance

SMUGDESK

SMUGDESK 0.75-0.8m 24G SlimSAS SFF-8654 8i InfiniBand Cable

SKU CH-PD19-R3S7E

An internal SlimSAS SFF-8654 8i cable for enterprise NVMe storage arrays and high-density servers, PCIe 4.0 compliant with 24Gbps bandwidth, 85-ohm impedance, and .75 to .8m fixed length

  • PCIe 4.0 Gen4 delivers 24Gbps bandwidth for NVMe storage speed
  • SFF-8654 8i SlimSAS connectors with 85-ohm impedance ensure signal integrity
  • Multi-layer shielding prevents EMI and packet loss under heavy load
  • LCP housing with lock latch resists loosening in data center use
  • 75-0.8m fixed length fits 1U/2U server chassis cleanly

Enterprise NVMe Connectivity

This 24Gbps SlimSAS SFF-8654 8i cable links NVMe all-flash storage arrays and RAID controllers inside high-density rack servers. It targets system integrators and data-centre operators who need PCIe 4.0 Gen4 bandwidth for U.2 SSD deployments. The fixed 0.75-0.8m length suits 1U and 2U chassis routing without excess slack. Builders who want longer runs or external connections should look elsewhere.

Sustained Signal Integrity

Multi-layer shielding and precise 85-ohm differential impedance eliminate crosstalk and phase deviation during continuous heavy-load operation. The design delivers zero packet loss under 24/7 enterprise workloads, maintaining full 24Gbps per lane throughput without thermal throttling. LCP connector housings withstand elevated temperatures inside packed server cabinets while positive lock latches prevent accidental disconnection from vibration. Installers who need field-terminable or hot-plug optical alternatives will not find those features here.

Connector Compatibility Decides Fit

Both ends use standard 74-pin SFF-8654 8i SlimSAS connectors, so the cable only works with matching controller and backplane ports. Verify that your NVMe storage array, RAID card or server midplane exposes this exact interface before ordering. The fixed length range of 2.46-2.62ft offers no adjustability for atypical chassis layouts. Teams deploying mixed connector types or requiring breakout configurations must select a different assembly.

Questions about this item

Does the cable generate heat or need extra power when running 24/7 at 24Gbps?

No, it is a passive copper assembly with no active components, so it draws no power and produces negligible heat even under continuous full-load traffic.

What must the server or storage array already have to use this SFF-8654 8i link?

Each end needs a standard SFF-8654 74-pin SlimSAS 8i port — typically found on PCIe 4.0 RAID controllers, NVMe backplanes or host-bus adapters.

Will it work reliably beside older SAS or PCIe 3.0 gear in the same chassis?

Yes, the multi-layer shielding and 85-ohm controlled impedance prevent crosstalk, so the cable coexists cleanly with legacy interfaces in dense 1U or 2U enclosures.
