Broadcom - SAS internal cable - Slim SAS (SFF-8654) (M) to U.2 (SFF-8639) - 1 m

Product Overview

AI-generated summary

This is one of those “it either fits and works perfectly, or it’s the wrong thing and you’ll be stuck” server-cable buys. The slim SAS (SFF-8654) to U.2 (SFF-8639) link is exactly what you want if you’re moving between modern backplanes or port layouts where the server side expects a slim connector and the drive side is U.2. At £51.42 ex-VAT for a 1m lead, it’s not cheap, but it’s also not shocking for a genuine Broadcom cable—especially if you’re trying to avoid flaky third‑party compatibility or hours of troubleshooting.

I’d buy it if you already know your backplane/server uses that specific connector pair and you’re doing a clean, supported replacement for a failed or missing internal cable. I wouldn’t buy it “just in case” unless you’ve confirmed both ends match exactly, because SAS connector ecosystems are picky and returning cabling is rarely fun. If you’re building from scratch and planning to standardise across a fleet, it’s worth checking whether your setup is consistently slim-to-U.2; otherwise you may end up paying for the wrong conversion cable more than once.
