Uncovering virtual networking Part-9: IOChain Framework

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

How to optimize Virtual machine vNIC transmit (Tx) performance?

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?

Uncovering virtual networking Part-8: Load balancing Algorithms

In previous post on Network failure detection, we started with the Teaming and Failover policies. We are going to explore load balancing algorithms in virtual networking in this post. This one is going to be the longest post I have written until now I guess 🙂 We have two types of switches, standard (vSS) and … Continue reading Uncovering virtual networking Part-8: Load balancing Algorithms

Uncovering Virtual Networking Part-3: Policy inheritance

Here is another instalment in this series. In my last post Part2: Virtual Switches, we discussed about switch types in vSphere. Now with this post we are entering into switch configurations and policies. Before I talk about these settings and policies in detail individually in later posts, in this post, first of all we will … Continue reading Uncovering Virtual Networking Part-3: Policy inheritance

vROPS 8.x: Configuring vSphere Solution Cloud Account

In this post we will see, what is cloud account in vROPS and how to setup cloud account for vSphere solution. The vSphere solution allows vROPS to connect to one or more vCenter Server instances. This is pretty much the starting point when configuring vROPS installation to collect data. Once connected to vCenter Server instance, vROPS collects data and … Continue reading vROPS 8.x: Configuring vSphere Solution Cloud Account

Uncovering Virtual Networking Part-2: Virtual Switches

As discussed in previous post Part-1: Basics, we have two types of switches that are available in vSphere i.e. Standard switch and Distributed switch. So in this post we will explore these switch types. But before we do that, let's dive into basics of switches in virtual architecture first. What is a virtual switch? A … Continue reading Uncovering Virtual Networking Part-2: Virtual Switches

Uncovering vSphere virtual networking Part-1: Basics

Welcome everyone to this series on vSphere virtual networking. This is going to be a long series due to the vast scope of configuration In this series, we will explore concepts related to vSphere virtual net possibilities in vSphere virtual networking. The reason of doing this series is basically to let everyone (specially beginners) understand … Continue reading Uncovering vSphere virtual networking Part-1: Basics
