Hello Guys !
I just picked a nice topic for this lazy Sunday night! As we have done some vSAN configurations previously, it just came up to my mind to have this topic today, so do we know what is fault domain in vSAN? It is very helpful protection way to keep vSAN cluster spans across multiple racks or blade server chassis.
My best practices notes for this subject;

Hello Guys!
Today we are going to use our VSAN disks for different resources!
First of all we need to activate ISCSI Target Service
The important part on this section is; which network will be used for ISCSI LUN? I’m going to pick VMK1 because this is my isolated network.
Hello Guys!
Today we are going to install VSAN on 3 node system. VSAN will be using vmkernel ports therefore we need to activate VSAN on vmkernel ports.
What is VSAN?
VSAN is allowing us to use our local disk drives as network based storage blocks. As this is first step for HA (High Availability) it is giving as an option for shared storage.
Before we start installation, we have to go each host to activate VSAN. I am suggesting to use VSAN on another network to isolate.And finally I strongly suggest that change; Jumbo Frame is coming as 1500 default, if you change that to 9000 it will help increase package size and it will help performance wise.

Hello Guys!
I have done my Vcenter update today and while on my first attempt, I realised that I forgot my ROOT password (Obviously it’s my lab so nothing to worry about it from my end
) and I thought it might be good to have post with this topic.

Hello Guys!
We are going to create NFS datasotre via FreeNAS on our ESXI.
First step we are going to do some changes on FreeNAS
Storage>Pools> (I’m gonna pick that) pool2> Add Dataset (This is the step creating a volume for our datastore)
After that Sharing>Unix(NFS) Shares> Add NFS share needs to be mounted
What is Overwrite Gateway? Where we can use it?
We use to use CLI console (ESXI 6.0) to set up some of the features to work on different subnets. (NFS, ISCSI, Vmotion etc.) and we were using manual routing via this CLI console. After ESXI 6.5 system allowed us to do to this changes from Vcenter.
It will help us to isolate management and vmkernel networks and it will give us additional security layer as well as also performance too.
Let’s have a look how we are going to make it; Continue reading “How to Define Vmware Overwrite Gateway?”
Hello Guys!
On Vmware environments sometimes we might need to run different type of CPU and we need to configure that as host system might have old and new type of CPU. We will do that via knowing maximum mode of the CPU.

Hello Guys!
I am planning to explain and show how to configure DNS and Time Server (NTP)
But have you think why this is so important?
With previous editions of ESXI systems (6.0) DNS was not such an important topic to think about it and we used to use windows based Vcenter host file, where we use host files on it and kind of fake DNS was our solution. After Vcenter become famous and also people were not Linux expert (Linux not as easy as like Windows OS) to setup host file…So that was my first reason to have proper records to have strong and proper system set up. . .

Hello Guys! Today we are not going to do configuration but today we will remove a configuration according to our needs etc. etc. So let’s think we have to remove / erase vmkernel adapter from distribution switch to create another new one!

Hello Guys,
We are going to connect ESXI console via SSH connection type. Sometime we might need to get console connection if we do not have direct access to the host device. In some cases you can remote in via Dell Idrac or Hp ILO but with this method we will have same connection type.
