You and your lab partner are both logged in and configuring target servers. Ensure that you interact only with the vCenter Server instance and ESXi host that are assigned to you.

Task 4: Add the ESXi Host Thumbprint to the vCenter Server

Certificate Store

You add the ESXi host thumbprint to the certificate store on the vCenter Server system so that a trust relationship exists between the host and the server. This trust relationship is necessary to run ESXCLI commands.

Use the following information from the class configuration handout: • ESXi FQDN

1. Run an ESXCLI command with no thumbprint stored. esxcli -s server hardware cpu list

server is the ESXi FQDN.

server is the ESXi FQDN.

As a result of running the command, the name of the target server appears as part of the command prompt.

2. Display the CPU characteristics of the ESXi host. esxcli hardware cpu list

3. Use the command output to determine CPU characteristics. • Number of CPUs installed on the host __________ • Brand of the first CPU __________

(18)

5. Use the command output to determine memory characteristics. • Amount of physical memory __________

• NUMA node count __________

6. Display the platform on which the ESXi software is installed. esxcli hardware platform get

When viewing the platform information in a nested environment, such as a class hosted on the VMware vClass2 platform, the return value is VMware Virtual Platform. In nonnested environments, this command returns the name of the hardware vendor.

7. Use the command output to determine platform characteristics. • Product name __________

• IPMI supported status __________

8. List the software version of ESXi that is installed on the host. esxcli system version get

9. Display the time and date on the host. esxcli hardware clock get

1. Yes.

Q2. Which test resulted in the highest throughput (highest values)?

2. The same port group test.

Q3. Why was this test the fastest?

3. Because the network traffic was contained within the port group, handled completely by the ESXi host, in software. Not only are general network operations faster in a purely software-defined scenario, but network mechanics, such as frame collision, are handled more efficiently.

3. In the Firefox window, leave the vSphere Web Client tab open for the next lab and close the

Linux01 and Linux02 console tabs.
