vSphere Distributed Resource Scheduler (DRS) is a feature of VMware's vSphere virtualization platform that automatically balances computing workloads across multiple servers in a data center to optimize resource utilization and minimize downtime. It monitors the resource usage of virtual machines and dynamically adjusts the distribution of workloads to meet the resource demands of each virtual … Continue reading VMware vSphere 7 DRS and its best practices.
vSphere 7 Lifecycle Manager is a new feature introduced in vSphere 7 that provides a centralized, automated and simplified way to manage and upgrade the lifecycle of vSphere infrastructure components such as vCenter Server, ESXi hosts, and NSX-T. With vSphere 7 Lifecycle Manager, you can upgrade your vSphere environment to the latest version in a … Continue reading vSphere 7 lifecycle manager
The IOChain is a group of functions that provides connectivity between virtual ports and the virtual switch. It also provides the capability to insert functions into the network data-path regardless of the switch type used i.e. Standard Switch (vSS) or Distributed Switch (vDS). A virtual port has two IOChains based on the direction i.e. to … Continue reading Uncovering virtual networking Part-9: IOChain Framework

https://youtu.be/ZxUVk0haIKA This post will be focussing specifically on working of CPU scheduler in Default, SCA v1 and SCA v2 modes in 6.7 U2 and later. VMware vSphere 6.7 U2 added new scheduler options (SCA v2) which provides security for L1TF vulnerability, while retaining as much performance as possible. Note: SCA is the abbreviation for Side … Continue reading vSphere 6.7 U2 & later CPU Scheduler modes: Default, SCA v1 and SCA v2
In this post, we will discuss about using single or multiple vNICS on a VM and vmkernel networking CPU threads to optimize transmission rate of VM traffic. We can create a VM with single vNIC or multiple vNICs depending upon operational requirements. Using multiple vNICS on a VM could be for different types of traffic … Continue reading How to optimize Virtual machine vNIC transmit (Tx) performance?
