Lenovo 7Z57A03551 InfiniBand/fibre optic cable 3 m Blue

Product Overview

AI-generated summary

At £2,336.84 ex‑VAT for a single 3 m Lenovo InfiniBand/fibre optic cable, this is the sort of item you only buy if you’re absolutely sure you need that exact Lenovo part in that exact InfiniBand setup. In most “normal” data-centre networking purchases, there’s wiggle room to choose equivalent optics/cabling from reputable vendors. Here, the price suggests you’re paying for brand/compatibility certainty and you should treat that as the *only* justification—don’t buy it just because it’s Lenovo if you could source something equivalent at a fraction of the cost.

Who should buy: teams with Lenovo‑centric infrastructure (or strict vendor support requirements), tight change-control, and a known part number requirement—e.g., replacing a failed link in an InfiniBand fabric where “almost compatible” is how you end up with downtime and finger-pointing. Who shouldn’t buy: anyone building new links from scratch, labs, smaller shops, or buyers who don’t have a documented requirement—because the cost-to-length ratio here is steep, and unless Lenovo compatibility is mandated, you’ll usually get better value with a tested equivalent from a supplier that explicitly supports your transceivers/standards. If you can’t clearly tie this specific cable to a confirmed need (and warranty/support constraints), I’d push back and get alternatives costed.
