Storage DRS
VM DRS balances VMs on ESXi hosts and gives the VMs the best possible startup point. Storage DRS is a similar technology that balances the vmdks over data stores. It is a technology that simplifies the datastore management. How to…

vSphere CPU Scheduler
In vSphere 6.7 VMware introduced CPU Scheduler options that allows the Administrators to secure against CPU exploits by defining how the VM access the CPU. These CPU Schedulers have different impact on performance. This article shows why and how they work.
Output of ESXtop results unreadable
Terminal on Mac uses by default xTerm-256color – this is not supported by ESXi and will result in garbled display when you run commands like ESXtop. To get an output that is readable we need to change the terminal display…
VMware Performance – CPU READY
A deep dive into CPU Ready time and the effects of it on VM running on VMware vSphere. The article explains the symptoms, what CPU ready is and what it is not and how to resolve it.
Distributed Resource Scheduler
DRS addresses where it is optimal for a VM to run. This is done to place the VM on the best ESXi host when the VM starts up based upon resources availability. The load balancing between Cluster nodes (ESXi hosts) is also based on moving VMs to another host that has less resource constraints.
vSphere FT
VMware HA and FT are often misunderstood. Here I will take a deep dive look at what FT provides, read this article for HA deep dive. What is vSphere FT vSphere Fault Tolerance (FT) is for most mission critical virtual…
Defining VM start order in case of VMware vSphere HA Event
Within vSphere 6.7 and later we can define the start order of VMs in a vSphere cluster in case of an HA event. This can be very useful for certain applications, like if the database server needs to be up…
