What is Virtualization

VIRTUALIZATION

As word Virtualization defines, convert some physical component into a digital form. When we talk about Server virtualization, we are talking about converting physical hardware into multiple or single digital segment. We also have different kind of virtualization concepts given below:

ü Server Virtualization: As explained above

ü Application Virtualization: Application runs on another host from where it is installed in a variety of way. For example, Application streaming, VDI, VM Package.

ü Network Virtualization: Segmenting physical NIC to multiple of digital NIC segments, Switches and VLANs etc.

ü Storage Virtualization: Physical available storage to multiple digital storage segment for Virtual machines.

VMware ESX is based on bear metal which means it can be install directly on physical hardware. No need of base OS in order to run it. In such case the virtualization architecture called as hosted virtualization architecture like VMware Workstation or Microsoft Virtual PC.

Then the source domain controller send the Update to replication partners. The delay between the time a change occurs and the time it is propagated to all domain controllers in the site is known as Replication Latency . 15 Sec for first direct replication partner (Configurable) 3 sec for rest replication partner (Configurable) Security updates like Password lock do not wait for 15 sec and replicates immediately and known as Urgent Replication . Changes can take place on any DC. It may possible that same change take place on multiple DC at same time and this ...

Enable SSH on ESXi 6.X

Working on your VMware environment, we often needed remote access to your ESXi hosts. Accessing the ESXi Host via SSH offers administrators the ability to maintain, troubleshoot, and remediate issues by using a Secure Shell client such as PuTTY. As per the security concern, SSH is disabled by default. However, you can enable it for remote command execution in multiple ways. In this post, we will provide you a walk through the different processes of enabling SSH on VMware ESXi 6.5 hosts. Let's go through one by one! Enable via Direct Console User Interface (DCUI) Login in ESXi Direct Console User Interface (DCUI) and Press F2 Key. It will ask you for root credentials. Now go to System Customization screen and select Troubleshooting Options. Under Troubleshooting, go to Mode Option and choose Enable SSH . SSH will show now Enabled. Press Esc to go back to main menu. Enable via vSphere Web Client (Host) Log into the ESXi via the Web Client. It must be https://localhostname/UI. Log in ...
