VM resources?

[omegahost]

Can anyone help me to understand Resources tab for each VM in esxi hosts?

Thanks

Sure, what exactly do you want to know?

Btw. did you see the "Help" link in the lower left corner of each resource box.

Hey,

The Resource tab of VM's setting is all about resource management.

You need to manage the resource alloacation from ESXi host to it's VM in situations when demand is more

than the capacity, overcommitmen scenarios, for example for RAM and CPU and Disk.

According to VMware:

"Resource management allows you to dynamically reallocate resources, so that you can more efficiently use available capacity."

On the Resource tab you can define three major settings;

1- Shares (Priority of your VM).

2- Limits (Maximum allocation).

3- Reservation (Minimum allocation).

Take a look at these links for more detailed info:

Thanks my friends

I use your helps and get the meaning of each option.

At general I think the default configuration for resource is better, isn't it?

Thanks

In General, the default configuration for resources will give good performance..

it gives complete insight in terms how vm is behaving with regards to esxi

what about Network.

Host has 1Gb speed. how can i limit one VPS to only 20Mb?

You can do this on the virtual port if you use a vNetwork distributed switch.  Distributed Switches are the way to go bu they only come with Enterprise Plus

I appreciate, if u could guide me to exact Help pages to find out what shoud i do exactly.

Sorry, i'm new to the VMware world.

The feature you are looking for is called traffic shaping.  Not sure why you are trying to set these limits at 20 Mbps this explains where it can be applied.

This article explains what to do at the vswitch level.  You would of course be applying this to all VMs that use that vswitch.  A messy work around would be to dedicate a vswitch for the VM you want to shape.

I doubt you are working with Enterprise Plus, but if you are, this should help you.
