DELL PERC H755 RAID controller PCI Express

Product Overview

AI-generated summary

Dell’s PERC H755 is one of those “built for the server room” RAID controllers that tends to make sense when you’re maintaining a Dell estate that already uses Dell backplanes, drive caddies and cabling conventions. If you’ve got a PowerEdge chassis that supports it, this can be a straightforward swap/upgrade with less drama than mixing-and-matching generic RAID hardware. The catch is the price: at ~£1,065 ex-VAT, you’re paying for an enterprise-grade, Dell-supported path—so it only really stacks up when downtime isn’t optional and you want vendor-aligned reliability and supportability.

Who should buy it? Teams running Dell PowerEdge servers with existing RAID layouts that need a proper controller replacement, expansion, or maintenance where you’d rather not take risks on compatibility. Who should *not*? If you’re building something from scratch on a non-Dell platform, or if you’re doing basic “keep it simple” redundancy for a small workload, this is probably overkill and expensive relative to your real needs. Also, if your storage is already managed elsewhere (e.g., you’re basically abstracting storage through NAS/SAN), you may be paying for RAID you won’t fully leverage.

If you tell me the exact PowerEdge model and what you’re trying to achieve (new build vs replacement, number/type of drives, and current RAID level), I can give you a clearer “worth it vs not” call.
