VMware vSphere 6.7 Data Center Design Cookbook - Third Edition

By: Mike Brown, Hersey Cartwright

Overview of this book

VMware is the industry leader in data center virtualization. The vSphere 6.x suite of products provides a robust and resilient platform to virtualize server and application workloads. This book uses proven infrastructure design principles and applies them to VMware vSphere 6.7 virtual data center design through short and focused recipes on each design aspect. The second edition of this book focused on vSphere 6.0. vSphere features released since then necessitate an updated design guide, which includes recipes for upgrading to 6.7, vCenter HA; operational improvements; cutting-edge, high-performance storage access such as RDMA and Pmem; security features such as encrypted vMotion and VM-level encryption; Proactive HA; HA Orchestrated Restart; Predictive DRS; and more. By the end of the book, you will be able to achieve enhanced compute, storage, network, and management capabilities for your virtual data center.

Determining the vCPU-to-core ratio

The number of virtual machine vCPUs allocated compared to the number of physical CPU cores available is the vCPU-to-core ratio. Determining this ratio will depend on the CPU utilization of the workloads.

If the workloads are CPU-intensive, the vCPU-to-core ratio will need to be smaller; if the workloads are not CPU-intensive, the vCPU-to-core ratio can be larger. A typical vCPU-to-core ratio for server workloads is about 4:1—four vCPUs allocated for each available physical core. However, this can be much higher if workloads are not CPU-intensive.

A vCPU-to-core ratio that is too large can result in high CPU ready times—the percentage of time that a virtual machine is ready but is unable to be scheduled to run on the physical CPU—which will have a negative impact on the virtual machine's performance.
