To get started with vSphere and vCenter Server, you may notice that there are 2 difference options: vCenter Server for Windows and vCenter Server Appliance. What are they and which one should you choose? Keep reading and this article will offer you the answer.
If you want to efficiently pool and manage VM resources across multiple hosts, vCenter Server is an excellent choice that you definitely don’t want to miss.
There are 2 options available for vCenter installation:
Therefore, if you use vSphere 6.7 or later versions, you need to deploy vCenter Server via VCSA. Next, this article will provide you more details on what is vCenter Server Appliance.
Different from Windows-based vCenter Server, VCSA is Linux-based. vCenter Server Appliance is a preconfigured virtual machine that is optimized for running vCenter Server and the associated services.
In addition, vCenter Server Appliance has several benefits such as more lightweight, faster and easier deployment, simplified maintenance, reduced hardware requirements, smaller attack surface over the Windows-based installation.
Another key advantage of VCSA is its scalability. VCSA can support up to 2000 hosts and 35000 virtual machines, making it a suitable solution for organization of all sizes. It is now the commonly accepted solution to install vCenter Server on ESXi host.
The vCenter Server appliance package contains the following software:
In addition to the above components, vCenter Server Appliance also comes with an intuitive web-based user interface, vCenter Server Appliance Management Interface (VAMI), making it easy for administrators to manage vSphere environments from any device with a web browser.
Take a look at the steps on how to check vCenter Appliance services via VAMI as an example.
1. In a Web browser, go to the vCenter Server Appliance Management Interface, https://appliance-IP-address-or-FQDN:5480.
2. Log in as root. The default root password is the password that you set while deploying the vCenter Server Appliance.
3. Click Services from the left inventory.
4. Check which services are stopped. Generally, the services which have a Startup Type of "Manual" or "Disabled" are not required services.
You may already know that it is necessary to perform image-based backup of large amounts of VMs managed by vCenter Server, however, vCenter Server does not provide the feature of virtual machine backup. And that makes backup software a commonly accepted choice.
Here I introduce you to a VMware backup software AOMEI Cyber Backup, it enables you to backup multiple VMs either managed by vCenter Server, or on a standalone ESXi host.
✦ Agentless Backup: create complete and independent image-level backup for VMware ESXi and Hyper-V VMs. ✦ Flexible vSphere Backup: batch backup large numbers of VMs managed by vCenter Server, or multiple VMs on a standalone ESXi host. ✦ Multiple Storage Destinations: backup to local drive, or network destinations like NAS. ✦ Automated Execution: create backup schedules to automate backups daily, weekly, monthly. ✦ Restore Entire VM: restore instant available VMs from any selected restore points to an original or new location.
AOMEI Cyber Backup supports both paid and free versions of VMware ESXi 6.0 and later versions. Next, I will show you how to batch backup VMs managed by vCenter Server with AOMEI Cyber Backup in 4 simple steps.
You can click the following button to download the 30-day free trial.
*You can choose to install this VM backup software on either Windows or Linux system.
1. Bind Devices: Access to AOMEI Cyber Backup web client, navigate to Source Device > VMware > + Add VMware Device to Add vCenter or Standalone ESXi host. And then click … > Bind Device.
2. Create Backup Task: Navigate to Backup Task > + Create New Task, and select VMware ESXi Backup as the Backup Type.
3. Set the Task Name, Device, Target, Schedule and Cleanup as needed.
4. Run Backup: Now you can click Start Backup and select Add the schedule and start backup now, or Add the schedule only.
Created backup tasks will be listed and monitored separately for restoring, progress checking and schedule changing.
When restoring, you can also restore to new location to create a new VM in the same or another datastore/host directly from the backup, saving the trouble of re-configuring the new VM.
vCenter Server Appliance is a lightweight and easy-to-use solution for vCenter Server installation and deployment. As VMware removed vCenter Server for Windows from download, you need to get comfortable with it from now on.
