We started with installing and configuring VMware vCenter Server in Objective 1.1. Now we move on to installing and configuring VMware ESXi as part of the VMware VCP5 certification. My first thought is why would the next objective go into ESXi.. shouldn’t that be the first objective? It’s probably because I install vCenter Server as a virtual machine after installing ESXi.
Objective 1.1 – Install and Configure vCenter Server
Objective 1.2 – Install and Configure VMware ESXi
Perform an interactive installation of ESXi
- Typically this would be done through a DVD, ISO, or USB drive to run the vSphere installer.
Below is a table of the vSphere 5.0 Editions. It’s handy to figure out which features are supported in each edition. Just note the Enterprise Plus supports everything.

Deploy an ESXi host using Auto Deploy
- Leverages PXE and host profiles.
- Auto Deploy server deploys image and host profile to each host.
- Rules engine determines which images and profiles to send to each host.
- Image profiles are VIBs (VMware Infrastructure Bundles).
- Host profiles hold ESXi host configuration.
- Answer files are used during boot process. One per each host.
- No state stored on the host – Auto Deploy server manages state information.

Configure NTP on an ESXi Host
1. Select the host in vSphere Client
2. Click on the Configuration tab and click on Time Configuration
3. Click on Properties and enable the NTP client in the Time Configuration window.
4. Click on Options in the Time Configuration window and under the General section start the NTP service.
5. Click on NTP Settings and click Add to add NTP servers.
Configure Routing and DNS on an ESXi Host
- Configure IP settings by using DHCP or static IP addressing.
- Configure IP settings from the DCUI.
- Select Configure Management Network
- Select IP Configuration
- Select Set static IP address and network configuration
- Enter IP address information
- Configure DNS manually or automatic (default).
- Can configure in DCUI.
- Should be enabled on the host BIOS first.
- Sometimes labeled as Logical Processor or Enable Hyperthreading.
- To Turn on hyperthreading on ESXi in vSphere Client:
- Click Configuration tab
- Select Processors and click Properties
- Turn On/Off hyperthreading
Enable/Size/Disable Memory Compression Cache
- VMkernel uses memory compression cache to make the most out of physical RAM when there is contention.
- Enabled by default.
- Set to default size of 10% of VM memory.
- To modify:
- Go to Configuration tab
- Click on Software and then Advanced Settings
- Click on Mem
- Edit Mem.MemZipEnable – 0 to disable; 1 to enable
License an ESXi Host
- Can use vCenter Server or vSphere Client or PowerCLI.
- Can use 60-day evaluation period for all features.
