VMware has announced an update to its flagship Cloud Foundation (VCF) private cloud suite and tried to make it fit the times by adding features that allow users to run with less hardware. VCF 9.1, announced today, tries to improve on VMware's memory tiering tech that shifts data out of RAM and onto NVMe storage, so that servers can get by with less memory. We're told the new version includes better detection of cold memory pages so VCF can shunt more data to NVMe, more often. VMware has already argued memory tiering is the antidote to soaring hardware prices, because it means users won't need to invest in RAM-crammed servers. Improved tiering many improve that argument. The Broadcom biz unit has also added what it describes as "next-generation storage compression" for AI data pipelines, an addition that should mean users need less storage capacity – another potential saving.…
