VMware vCenter Server is a service that acts as a central unified administrative management tool for VMware ESXi hosts connected in a network. vCenter Server enables you to pool and manage the resources of multiple hosts using Clusters. You can install vCenter Server on a Windows host machine or you can deploy VMware vCenter Server Appliance or simply vCSA. vCSA is a preconfigured Linux-based virtual machine . As vCSA comes with a pre-configured database vPostgress so deploying it makes your life a lot easier. Also with vSphere 6 vCSA can manage 1000 Hosts or 10K powered on VM hence on par with its windows sibling. However the VMware vSphere Update Manager remains with the windows version.
vCSA provides advanced features such as VMware vSphere Distributed Resource Scheduler, VMware vSphere High Availability, VMware vSphere Fault Tolerance, VMware vSphere vMotion, and VMware vSphere Storage vMotion.
There has been considerable amount of changes as is the case with every version change, Previously vCSA 5.5 composed of four components
2) Inventory service
3) Web Client
4) vCenter Server
The Platform Services Controller is bundle of following components :
vCenter server includes services such as VMware vCenter Inventory Service, VMware vSphere Web Client, auto deploy, etc are installed along with vCenter Server. So VMware has reduced the complexity of our deployment from four components to two.
We have two different deployment methods :
1) Embeded PSC and vCenter Server : Here no replication between vCenters deployed in the same datacenters
2) External PSC and vCenter Server : If replication exists between vCenter instances
Vmware has experimented with a new browser based installation of vCenter, I would recommend everyone to go for vCSA rather than a windows vCenter, it has same capabilities now and it is optimised for vSphere. Firstly download the package from MYVMware.com, and extract the files.
Kindly close your browser and FIRST install VMware Client Integration plugin 6.0 , After that you can click on a HTML file and open it with Internet Explorer .
This first page would ask you is whether to upgrade from previous version or Install a new copy. Accept EULA , Provide your Host credentials where you would install VCSA 6.0 as in the below image.
Accept Certificate warning, also provide the name of vCSA and set Operating system password for the same, this is a new feature in vCSA 6 and comes with DCUI like ESXi , Select the deployment type depending upon size of VM’s you will manage. I choose embedded deployment.
This is another new feature in vCSA 6 , Create a new SSO domain name or use the default “vsphere.local” , I generally use this default because I have been using the same since many years and I tend to forgot it if I use a new domain name. Provide the password that you will use to log in to vCSA also provide Site name.
Select appliance size , Ideally I choose Tiny deployment. Choose the datastore you want to deploy vCSA and also check “Enable Thin Disk Mode”. Choose vPostgres as Database.
This is the final step , Provide Network address , FQDN, Masking , Gateway, DNS and for NTP choose ESXi to provide time. Review your changes and begin installation. This new Wizard involves both deployment and configuration of vCSA. Once you have successfully deployed vCSA , you can log into WebClient using https://<IP address of vCSA>:9443 in your browser .
