vSAN ready nodes in 2026: certified hardware, disk groups and sizing after Broadcom (UK)
A vSAN cluster is only as supportable as the hardware underneath it, and vSAN is unusually fussy about that hardware. Buy a server that merely looks adequate and you can end up with a configuration VMware will not suppor…
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…
HPE ProLiant DL340 Gen12 buyer's guide: the storage-dense 1U newcomer (UK 2026)
Most 1U servers force a hard trade: you can have compute or you can have drives, but not many of both. The ProLiant DL340 Gen12 is HPE's answer to that compromise, a 1U designed to carry an unusually generous number of d…

HDD vs QLC vs TLC: choosing and tiering storage media in 2026 (UK)

How much storage (and what tiers) does your server need? (UK 2026)
Internal server storage is usually sized by guesswork: a capacity number plucked from the last server, a single drive type for everything, and no thought to how the boot, cache and data layers should differ. That leaves …
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)
