Plan your VMware Cloud Foundation 9 Memory Tiering deployment with intelligent sizing, compatibility checking, and cost analysis based on official VMware guidance.
Current or planned DRAM per host
Average active memory across workloads
Higher ratios require lower active memory
Total active memory should be 50% or less of DRAM capacity to ensure active pages stay in fast DRAM tier.
NVMe partitions support up to 4TB. Purchase larger devices for future ratio adjustments without repartitioning.
DRAM:NVMe ratio can be changed dynamically (1:1 to 1:4) without recreating partitions, enabling workload adaptation.
Memory Tiering is NOT suitable for the following workload types:
For mixed environments, dedicate hosts or disable Memory Tiering at the VM level.
Based on VMware Cloud Foundation 9 NVMe Memory Tiering Design and Sizing guidance (5-part blog series by Dave Morera, Broadcom).
