Specifying a Veeam backup repository: hardware for a hardened, fast-restore target (UK 2026)
Plenty of guides tell you which backup software to buy. Far fewer tell you how to build the box the backups land on — and a badly-specified repository is where slow restores and broken immutability come from. This is how…
What is a DPU (SmartNIC)? Offload, isolation and vSphere DPU explained
A DPU, or data processing unit, is the third programmable processor that has quietly appeared inside modern servers, alongside the CPU and the GPU. In its more familiar guise it is a SmartNIC: a network card with its own…
Specifying an Active Directory domain controller without over-building it (UK 2026)
The domain controller is the server people reflexively over-build. It sits at the centre of everything, so the instinct is to throw a big two-socket box at it - which is almost always the wrong call. Active Directory is …
Single-socket vs dual-socket servers: which do you actually need? (UK 2026)
For two decades the default enterprise server was a dual-socket box, and most buyers still tick that option without thinking. That habit deserves a fresh look. Modern single-socket Intel Xeon 6 and AMD EPYC processors no…
Specifying a SQL Server or Oracle database host: cores, licensing and NVMe (UK 2026)
A database host is the one server where buying the wrong CPU costs you twice — once for the silicon, and every year after in per-core database licences. Get the core count, memory and storage latency right and a modest t…
What is CXL (Compute Express Link)? A plain-English guide for server buyers
CXL, or Compute Express Link, is one of those acronyms that has gone from research curiosity to a line item on server spec sheets in a remarkably short time - and most buyers have never had it explained plainly. In one s…
Spec'ing a VDI host in 2026: GPU, RAM density and users-per-host (UK)
A VDI host is not a general virtualisation host with desktops bolted on. The economics live and die on users-per-host, and that number is set by three things working together: how much frame buffer each session needs, ho…
Building a file and NAS server: capacity, ZFS or Storage Spaces and 10/25GbE (UK 2026)
A file server looks like the simplest box in the rack until you have to build one that stays fast for fifty people, never loses a byte and still has room to grow in three years. Capacity is the easy part; the decisions t…
DIMM population rules: how to fill memory slots for full bandwidth (UK 2026)
Two servers with identical CPUs and the same total RAM can differ by a third in memory bandwidth, purely because of how the DIMMs were placed in the slots. Memory population is not cosmetic - it decides whether you get t…
Scale-out vs scale-up storage: choosing an architecture before you buy hardware (UK 2026)
Before you compare arrays or price drives, there is a more fundamental fork in the road: do you grow storage by making one system bigger, or by adding more systems that act as one? Scale-up and scale-out are not just two…
