Thought of putting it all together in one place, all the relevant basic information for a System Administrator to manage daily VMware-based operations. Still, it’s incomplete, I will be continuously updating this post as and when I collect the relevant required information to add. As of now here are few pieces of information that I find useful in my daily operations hope you as well find it helpful.
Management Console URL
- Appliance VAMI : This is a console for vCenter Appliance management, you can able to check health metrics of appliance such as DB, vCPU, Memory and disk usage. Additionally You can configure backup of vCenter config backup from this console. The URL to access this : https://(vCenter fqdn or IP address):5480
- vCenter Console: This console is the management console from where you will be able to manage virtual environment, from version 6.0 onwards VMware strategy is to enhance and make webbed console as a primary mode of console for administration. The URL to access console: https://(vCenter fqdn or IP address). For vCenters version 5.5x or 6.0 the URL to access console will be: https://(vCenter fqdn or IP address):9443
- Standalone : From version 6.x onwards esxi as well are accessible over https, it is similar to manage the single ESXi host using windows based vSphere client. The URL: https://(ESXi fqdn or IP address)
Note: vSphere Client is deprecated, it’s used only for accessing ESXi and vCenter 5.x and 6.0. Hence fourth web browsers will be used for accessing management consoles.
Basic Firewall Rules
- To access Management Console : 443 (https), 9443 (version 5.x and 6.x), 5480 (VAMI), 22 (SSH in case of Appliance).
- In case of Separate PSC: 2012, 2014, 2020
- 443 (https), 22(SSH), 902(VM console based MKS related activities) ,514 (NTP)
Site Recovery Manager
- 443, 902 (Between SRM Appliance and vCenter/ESXI) “Not required if vCenter and Site Recovery manager are in same network subnet”
- 443, 1433(External MS-SQL), 1521(Oracle DB). (If you opt to choose external Database instead of embedded Appliance database).
Planning and Compatibility Check
- Checking Interoperability | Upgrade Path
The Portal is to check the VMware Solution, Database interoperability compatibility. In addition, it helps to decide the upgrade path.
- Checking Compatibility
The Portal is to check the VMware ESXi compatibility with the hardware manufacturing companies and assist to make better decisions while planning the solution.

Design and Best Practices
VMware validated Design
VMware Validated Design(VVD) is a family of solutions for data center designs that span compute, storage, networking, and management, serving as a blueprint for your Software-Defined Data Center (SDDC) implementation. VVD is a framework to design the SDDC solution. I must say this document so useful from the Sys Admin as well as Architect perspective, and you should at least go through once, thought the document is very extensive but its worth the read.
Services Related commands
vCenter Appliance (It is assumed that you must have logged in to VCSA appliance via Putty)
|List All Services||service-control –list|
|Check the status of services (Stopped or Running)||service-control –status|
|Stop All Services||service-control –stop –all|
|Stop Specific Service||service-control –stop service servicename|
|Start All Services||service-control –start–all|
|Start Specific Service||service-control –start service servicename|
Windows vCenter: Windows based vCenter still exist in some organizations where there is an compliance related adherence and some has application level dependency, however it is best to use appliance based vCenters for the new deployments. Steps to handling Windows based vCenter is very simple and straight forwards since it is installed on top of Windows Operating system.
|For vCenter version 5.x||All the vCenter based Services can be managed via “Windows Services” section|
|For vCenter version 6.x||Open Command prompt|
cd C:\Program Files\VMware\vCenter Server\bin
Follow the same commands used above for vCenter Appliance
