Starting now, if you pass this 2V0-21.20 exam, you will not be required to pass the broader vSphere Foundations exam.

New features of DRS in VMware vSphere 7.0 have been introduced to make VMware’s compute control plane robustly and better handle both traditional and modern application needs.

In this document, Priyanka Gayam and Adarsh Jagadeeshwaran cover the load balancing aspect of the new DRS, which is available in vSphere 7.0. Note that they refer to the older load-balancing version of DRS (vSphere 6.7 and older) as the old DRS.

VMware's performance engineers observed, under certain conditions, that ESXi IO (in versions 6.x – 7.0) with some NFS servers experienced unexpectedly low read throughput in the presence of extremely low packet loss, due to an undesirable TCP interaction between the ESXi host and the NFS server.

In this paper, Kinson Ho explains how this TCP interaction leads to poor ESXi NFS read performance, describes ways to determine whether this interaction is occurring in an environment, and presents a workaround for ESXi 7.0 that could improve performance significantly when this interaction is detected.

This book, Performance Best Practices for VMware vSphere 7.0, provides performance tips that cover the most performance-critical areas of VMware vSphere 7.0.

This book consists of the following chapters:

• Chapter 1, “Hardware for Use with VMware vSphere,” provides guidance on selecting hardware for use with vSphere.
• Chapter 2, “ESXi and Virtual Machines,” provides guidance regarding VMware ESXi™ software and the virtual machines that run in it.
• Chapter 3, “Guest Operating Systems,” provides guidance regarding the guest operating systems running in vSphere virtual machines.
• Chapter 4, “Virtual Infrastructure Management,” provides guidance regarding infrastructure management best practices.
