If hardware price squeezes make you sad, VMware says it will all end in tiers
Virtzilla finding more ways to pull data out of DRAM to enable ‘densification’ and dodge the RAMpocalypse
VMware is exploring new uses for its memory tiering technology amid persistently high memory and hardware prices. The technique moves data out of DRAM and onto fast NVMe drives, allowing CPUs to access information without slowing application performance. Introduced last year in version 9 of Cloud Foundation, VMware's memory tiering now includes performance enhancements for databases and added management tools.
The technology supports approximately 75% of workloads and aims to increase this percentage by accommodating Microsoft's Radius cloud-native application platform and monster VMs with up to 960 vCPUs and 16TB of memory. VMware engineers are working on improving memory tiering's performance for vMotion, the method of moving VMs with minimal downtime, and plan to roll out further enhancements in the VCF 9.2 release around May 2027.
By using memory tiering, organizations can lower CPU cycles by up to 30% and cut the cost of ownership by 40%, as servers can be densified into fewer units.
