Transforming Datacenter Economics: Unlocking VM Density with VMware’s Memory Tiering
In recent news, VMware has introduced Memory Tiering within VMware Cloud Foundation (VCF) 9.0, a feature designed to significantly enhance memory utilization. By targeting one of the largest cost components in server infrastructure—memory—this innovation promises IT professionals the potential to double VM density while cutting total cost of ownership by up to 40%. This shift not only optimizes existing resources but also spurs a transformation in how datacenter economics are approached.
Key Details:
- Who: VMware
- What: Introduction of Memory Tiering in VCF 9.0
- When: Available now
- Where: Applicable within VMware Cloud Foundation environments
- Why: Aims to improve memory efficiency and VM density, addressing high memory costs
- How: Memory Tiering creates a single logical memory space for VMs that dynamically manages the allocation of DRAM and NVMe memory based on workload activity, enabling optimal performance without compromising speed.
Deeper Context:
Memory Tiering significantly enhances VM performance by intelligently managing memory usage. It operates under a dual-tier architecture, placing frequently accessed “hot” memory on DRAM and less active “cold” memory on NVMe — appearing seamlessly to the VM as a single, larger memory pool.
This capability is especially crucial given the current trends toward hybrid and multi-cloud strategies, where resource optimization remains vital. By effectively addressing memory underutilization, organizations can enhance workloads without the corresponding increases in infrastructure costs. Notably, tests conducted across diverse workloads, including SQL Server and VDI applications, demonstrated a 2x increase in VM density with only minimal degradation in performance—generally within 0-10% loss depending on the workload.
Takeaway for IT Teams:
IT professionals should consider leveraging Memory Tiering to maximize resource utilization while managing costs efficiently. Monitoring active memory levels and NVMe read latency will be crucial for maintaining optimal performance as you scale.
