Location of the Main Console

 

  1. The area in the RED box contains the Main Console.  The Lab Manual is on the tab to the Right of the Main Console.
  2. A particular lab may have additional consoles found on separate tabs in the upper left. You will be directed to open another specific console if needed.
  3. Your lab starts with 90 minutes on the timer.  The lab can not be saved.  All your work must be done during the lab session.  But you can click the EXTEND to increase your time.  If you are at a VMware event, you can extend your lab time twice, for up to 30 minutes.  Each click gives you an additional 15 minutes.  Outside of VMware events, you can extend your lab time up to 9 hours and 30 minutes. Each click gives you an additional hour.

 

 

Alternate Methods of Keyboard Data Entry

During this module, you will input text into the Main Console. Besides directly typing it in, there are two very helpful methods of entering data which make it easier to enter complex data.

 

 

Click and Drag Lab Manual Content Into Console Active Window

You can also click and drag text and Command Line Interface (CLI) commands directly from the Lab Manual into the active window in the Main Console.  

 

 

Accessing the Online International Keyboard

 

You can also use the Online International Keyboard found in the Main Console.

  1. Click on the Keyboard Icon found on the Windows Quick Launch Task Bar.

 

 

Activation Prompt or Watermark

 

When you first start your lab, you may notice a watermark on the desktop indicating that Windows is not activated.  

One of the major benefits of virtualization is that virtual machines can be moved and run on any platform.  The Hands-on Labs utilizes this benefit and we are able to run the labs out of multiple datacenters.  However, these datacenters may not have identical processors, which triggers a Microsoft activation check through the Internet.

Rest assured, VMware and the Hands-on Labs are in full compliance with Microsoft licensing requirements.  The lab that you are using is a self-contained pod and does not have full access to the Internet, which is required for Windows to verify the activation.  Without full access to the Internet, this automated process fails and you see this watermark.

This cosmetic issue has no effect on your lab.  

 

 

Look at the lower right portion of the screen

 

Please check to see that your lab is finished all the startup routines and is ready for you to start. If you see anything other than "Ready", please wait a few minutes.  If after 5 minutes your lab has not changed to "Ready", please ask for assistance.

 

Module 1 - vSAN Configuration (30 minutes)

Introduction


Are you ready for vSAN Configuration Challenges?

This Module contains the following challenges:

Please note that these Challenges assume a certain level of vSAN familiarity to complete 'on your own'.  Fear not, in the event that you are not as familiar, you can still take the Lab and utilize the '(HINT)' links to thoroughly guide you through detailed completion steps for each Challenge.  There also may be more than one method to solve a challenge.  The goal is for you to learn and/or validate your existing knowledge along the way.


Challenge 1: Enable vSAN


It is very easy to enable vSAN. The only pre-requisites that must be in place prior are the configuration of a network interface for vSAN traffic and at least (1) Cache device and (1) Capacity device installed in your Server (or Storage Blade Modules) that you would like to be contributing storage to your vSAN Cluster.

Since vSAN is integrated directly into vSphere there are no Virtual Appliances to install or manage per Host.  In addition, since the vSAN Datastore is an object based filesystem, we no longer need to worry about formatting a VMFS Datastore.  vSAN takes complexity out of your Storage Environment by eliminating the need for LUNs and the associated questions around how to size LUNs, how many LUNs should be required, etc.

Let's get started!


 

Open Chrome Browser from Windows Quick Launch Task Bar

 

  1. Click on the Chrome Icon on the Windows Quick Launch Task Bar.

 

 

Introduction

For your first Challenge, you will be required to configure a vSAN Cluster that has the following characteristics:

  1. 3-Node vSphere Cluster
  2. Deduplication and Compression Required
  3. 1x Disk Group per Host (containing 1x Cache Device and 2x Capacity Devices)

Note: vSAN Networking has already been configured

 

 

Your Challenge: Create a vSAN Cluster

Perform the steps listed below in order to begin the Challenge.

  1. Configure vSAN (Hint)
  2. Configure vSAN Capabilities to leverage Deduplication and Compression but do NOT configure Encryption or Fault Domains (Hint)
  3. Validate Network (Hint)
  4. Create 1 Disk Group per Host.  Change your 'Group By:' Selector to Host view and Claim Disks using 1x 5GB Cache Device and 2x 10GB Capacity Devices per Diskgroup.  (Hint)
  5. Review your Ready to Complete selections and complete the Workflow to enable vSAN (Hint)
  6. Monitor vSAN Datastore creation progress until complete (Hint)
  7. Confirm that the vSAN Datastore has been formed and that Dedupe & Compression are enabled (Hint 1) (Hint 2)

Challenge 2: vSAN Configuration Assist


An important aspect of a healthy vSAN environment is ensuring correct configurations, device firmware, and device drivers. vSAN 6.6 includes a new vSAN Configuration Assist option to check hardware compatibility, burn-in testing, network configuration, vSAN configuration and adherence to VMware cluster recommendations.


 

Introduction

For this Challenge, you are required to utilize vSAN 6.6 Configuration Assist to enable adherence to VMware Cluster Setting recommendations.  In the event of a vSphere Host failure, it is very important that vSphere HA is enabled so that any impacted Virtual Machines are automatically restarted on another functioning Host in the vSAN Cluster.

 

 

Your Challenge: Utilize vSAN Configuration Assist

Perform the step listed below in order to begin the Challenge.

  1. Use Configuration Assist to ensure that vSphere HA is enabled ()

Challenge 3: vSAN Health Check


vSAN includes a wide range of Health Checks that actively monitor your vSAN environment for potential issues.


 

Introduction

For this Challenge, you are required to utilize the vSAN Health Check to see if there are any Errors and/or Warnings present in your environment.

 

Conclusion


In this Module you flexed your Software Defined Storage Muscles by easily enabling your vSAN Cluster.  In addition, you utilized the new vSAN 6.6 Configuration Assist option to ensure that VMware recommended settings were adhered to.  You finished by spinning through the vSAN Health check capability and responded to a Warning that was present indicating that you should enable the vSAN Performance Service.

Challenge 1: Scale vSAN Out and Up


You've done your Homework and built the perfect vSAN 3-Node Cluster only now those pesky users are demanding more Compute resources and more Storage Capacity.

Time to get back to work!


 

Open Chrome Browser from Windows Quick Launch Task Bar

 

  1. Click on the Chrome Icon on the Windows Quick Launch Task Bar.

 

 

Scale Out Introduction

A new Project has spun up out of nowhere in your Organization requiring additional Virtual Machines and associated Hyper-Converged Storage.  Your 3-Node vSAN Cluster is going to need to grow, and fast!  In this Challenge, you will be expected to scale out your vSAN Cluster by adding an additional vSphere Host and ensuring there are no service disruptions during this process.

The vSAN vmkernel network interface has already been configured by way of the vSphere Distributed Switch (vDS).  Although vSAN supports a vSphere Standard Switch (vSS), using a vDS has plenty of benefits like ensuring consistency across your Cluster and easing the Administrative tasks required when adding new Hosts!

 

 

Your Challenge: Scale Out your vSAN Cluster

Perform the steps listed below in order to begin the Challenge.

  1. Check your existing vSAN Cluster Capacity (Hint 1) (Hint 2)
  2. Add esx-04a.corp.local to your existing vSAN Cluster (Hint)
  3. Exit Maintenance Mode for esx-04a.corp.local (may require Web Client refresh) (Hint)
  4. Create a Single Disk Group using these parameters (Hint)
    • 1x Cache Device (5 GB)
    • 2x Capacity Device (10 GB)
    • 1x 'Spare' (Unclaimed Cache Device) (5 GB)
    • 2x 'Spare' (Unclaimed Capacity Devices) (10 GB)
  5. Confirm that your newly added Compute and Capacity is available (Hint 1) (Hint 2)

You can also view hints on the VMware Technology Network Communities here:

https://communities.vmware.com/docs/DOC-37005

 

 

Scale Up Introduction

Not satisfied with the additional Compute node you just added, you decide that you better add even more Storage Capacity to your existing vSAN Cluster.  Your ace Datacenter 'boots on the ground' team has just installed 2x additional SSD Capacity drives per Host.  Now it's your job to scale up the Capacity for each Host by adding these drives to your vSAN Diskgroups and ensure that there are no service disruptions during this process.

 

 

Your Challenge: Scale Up your vSAN Cluster

Perform the steps listed below in order to begin the Challenge.

  1. Create a new Disk Group on each Host utilizing the unclaimed drives (could there be an exciting new vSAN 6.6 Configuration Assist feature that helps simplify this process and alleviates the need to do this individually on each Host)? (Hint)
  2. Confirm that each Host now contains a 2nd Disk Group (Hint)
  3. Confirm that your newly added Capacity is available (Hint)

You can also view hints on the VMware Technology Network Communities here:

https://communities.vmware.com/docs/DOC-37005

 

Challenge 2: Configure Storage Policies


Virtual SAN storage polices define storage requirements for your virtual machines. These policies determine how the virtual machine storage objects are provisioned and allocated within the datastore to guarantee the required level of service.

When you enable Virtual SAN on a host cluster, a single Virtual SAN datastore is created and a default storage policy is assigned to the datastore.

When you know the storage requirements of your virtual machines, you can create a storage policy referencing capabilities that the datastore advertises. You can create several policies to capture different types or classes of requirements.

Each virtual machine deployed to Virtual SAN datastores is assigned at least one virtual machine storage policy. You can assign storage policies when you create new virtual machines or you can apply them on-the-fly to existing (running) virtual machines.


 

Open Chrome Browser from Windows Quick Launch Task Bar

 

  1. Click on the Chrome Icon on the Windows Quick Launch Task Bar.

 

 

Storage Policy Based Management Introduction

Life was going good until you received an urgent message indicating that you needed to quickly change the Storage characteristics for an existing Virtual Machine (and limit the amount of IOPS that it is able to consume).  There are other VM's residing on your vSAN Datastore, increasing concerns about Noisy Neighbor conditions originating from your 'problem' VM that could negatively impact the environment.  In addition, you would like to reduce the amount of space that this VM is utilizing.

With traditional Storage Array's you would need to ask your Storage team to provision a new LUN with new Storage capabilities (and you would then have to format this as a new VMFS Volume and migrate your VM to this new Datastore).

Within the VMware Software-Defined-Datacenter (SDDC) and vSAN Software Defined Storage (SDS) you can make these changes on-the-fly with no impact to your environment (and without having to interface with another team).  

 

 

Your Challenge: Configure Storage Policy

Perform the steps listed below in order to begin the Challenge.

  1. Create a new VM Storage Policy that has these vSAN Storage Capabilities (Hint)
    • Primary level of failures to tolerate: 1
    • Failure tolerance method: RAID-5/6 (Erasure Coding)
    • IOPS limit for object: 50
  2. Apply newly created Policy to Virtual Machine named, "vSAN-VM_NoisyNeighbor" (Hint)
  3. Check Policy Compliance (Hint)
  4. Check IOPS Limit (Hint)

 

Challenge 3: Monitor vSAN Performance


vSAN 6.6 includes new Performance metrics that can be monitored via the vSphere Web Client. In this section, we Challenge you to examine Performance views for three separate vSAN related contexts:

 


 

Open Chrome Browser from Windows Quick Launch Task Bar

 

  1. Click on the Chrome Icon on the Windows Quick Launch Task Bar.

 

 

Your Challenge: Monitor vSAN Performance

Perform the steps listed below in order to begin the Challenge.

  1. Find and Explore vSAN Cluster Performance Metrics (Hint)
  2. Find and Explore Individual vSAN Host Performance Metrics (Hint)
  3. Find and Explore Individual Virtual Machine vSAN Performance Metrics (Hint)

You can also view hints on the VMware Technology Network Communities here:

https://communities.vmware.com/docs/DOC-37005

 

Conclusion


My, how far you have come in such a short amount of time.  Thanks to the scalable nature of vSAN you were able to not only quickly add additional Compute power but also extra Storage Capacity.  You also experienced first-hand the powerful ability to control vSAN Space Efficiency, Availability and Performance via Software-Policy Based Management.  Lastly, you armed yourself with knowledge around where to go when looking to Monitor vSAN Performance Metrics.

Challenge 3: vRealize Operations Manager (vSAN Operations)


Accurate interpretation of metrics in the data center is critical to the efficient design, operation, and optimization of any environment. Native (built-in) vSAN monitoring extends the powerful abilities of vRealize Operations (vR Ops) to bring the right information to the eyes of the Administrator running vSAN. This built-in capability exposes vSAN related metrics through predefined dashboards that are designed to assist in common operation and optimization efforts.


 

Your Challenge: Utilize the vR Ops 6.6 Management Pack to assess the Operational state of vSAN 6.6

This part of the lab is presented as a Hands-on Labs Interactive Simulation. This will allow you to experience steps which are too time-consuming or resource intensive to do live in the lab environment. In this simulation, you can use the software interface as if you are interacting with a live environment.

  1. Click here to open the interactive simulation. It will open in a new browser window or tab.
  2. When Finished, click the "Return to the lab" link at the top right.

Challenge 4: vRealize Operations Manager (vSAN Capacity)


vSAN provides capacity related data in vCenter, but it is a single point in time and one Cluster at a time.  Administrators are unable to see utilization trends, how it relates to other resources (CPU, Memory) and what utilization looks like across the data center.

vRealize Operations provides a holistic view of capacity.  Trending, correlations between other resources and visibility across Clusters.

Capacity management is a strategic effort for an Administrator.  They must have the right information to make smart design and purchasing decisions.

Challenge 5: vRealize Operations Manager (vSAN Troubleshooting)


Datacenter Administrators can face uncertainty in how to Troubleshoot issues in a vSAN (or any other) environment.

vRealize Operations provides a "Troubleshoot vSAN" dashboard presenting information in such a way to help specifically guide a user through a vSAN Troubleshooting process.

This gives the Administrator not only the necessary data but most importantly a repeatable process to more easily identify and resolve outstanding issues.


 

Your Challenge: Utilize the vR Ops 6.6 Management Pack to assess the Operational state of vSAN 6.6

This part of the lab is presented as a Hands-on Labs Interactive Simulation. This will allow you to experience steps which are too time-consuming or resource intensive to do live in the lab environment. In this simulation, you can use the software interface as if you are interacting with a live environment.

  1. Click here to open the interactive simulation. It will open in a new browser window or tab.
  2. When finished, click the “Return to the lab” link to continue with this lab.

The lab continues to run in the background. If the lab goes into standby mode, you can resume it after completing the module.

Conclusion


In this module you learned about a technique that could be used to Monitor and Administer vSAN in the event that vCenter is offline by using the vSphere Host Client.  In addition, you learned how vSAN is further enhanced through the use of other VMware products like vRealize Log Insight and vRealize Operations Manager.

Module 6 - Bonus Challenge (vSAN Encryption)

Introduction


This Bonus Module contains the following challenge:

Please note that this Challenge assumes a certain level of vSAN familiarity to complete 'on your own'.  Fear not, in the event that you are not as familiar, you can still take the Lab and utilize the '(HINT)' links to thoroughly guide you through detailed completion steps for this Challenge.  There also may be more than one method to solve this challenge.  The goal is for you to learn and/or validate your existing knowledge along the way.


 

Lab Preparation

Important Note:  If you have taken any of the previous challenges already in the same Lab session, you do not need to use the Module Switcher for this Challenge and you can proceed to Challenge 1: Enable vSAN Encryption.

If you have just started the Lab and have gone directly to this Challenge, please use our Module Switcher PowerCLI Application to prepare the environment by following the next set of instructions.

 

 

Module Switcher

 

Double-Click the Module Switcher Desktop Shortcut

 

 

Module 6 Start

 

1. Click the Module 4 Start button (this is not a typo - even though we are in Module 6, the PowerCLI code used for Module 4 is sufficient to prep our environment)

 

 

Monitor Progress

 

Monitor Progress until Complete.

• Press Enter to continue (and close the PowerCLI Window)

Note that it can take several minutes for the Module switcher to complete - thank you for your patience!

 

 

Lab Prep Complete

 

Your Lab has been successfully prepared for Module 6!

1. Click Window Close to safely stop the Module Switcher

Please Note that you cannot 'go back' and take Modules prior to the one you are  currently in unless you end the lab and start it over again (for example: If you Start Module 4, you cannot use the Module Switcher to Start Labs 1, 2 or 3).

 

Challenge 1: Enable vSAN Encryption


It's possible to enable vSAN Encryption the first time you form a vSAN 6.6 Cluster.  In our case, due to a recent Security requirement that has come up in your environment, we are going to ask you to enable it after the fact.


 

Open Chrome Browser from Windows Quick Launch Task Bar

 

  1. Click on the Chrome Icon on the Windows Quick Launch Task Bar.

 

 

Encryption Introduction

vSAN Encryption is the industry's first native HCI encryption solution and is built right into the vSAN software. With a couple of clicks, it can be enabled or disabled for all items on the vSAN datastore, with no additional steps.

Because it runs at the Hypervisor level and not in the context of the virtual machine it is virtual machine agnostic.

Since vSAN Encryption is hardware agnostic, there is no requirement to use specialized and more expensive Self-Encrypting Drives (SEDs), unlike some other HCI solutions that offer encryption.

To use vSAN Encryption, just like VM Encryption, a Key Management Server (KMS) is required. Nearly all KMIP 1.1-compliant KMS vendors are compatible, with specific testing completed for vendors such as HyTrust, Gemalto, Thales e-Security, CloudLink, and Vormetric. These solutions are commonly deployed in clusters of hardware appliances or virtual appliances for redundancy and high availability.

In this Challenge, a KMS is present in our Lab environment but vCenter is not configured to use it.  That's Step 1 of where you come in!

 

 

Your Challenge: Enable vSAN Encryption

Perform the steps listed below in order to begin the Challenge.

  1. Add Key Management Server (KMS) to vCenter using these parameters (Hint)
    • Cluster Name: KMS Cluster
    • Server alias: KMS
      Server address: 192.168.110.81
    • Server port: 5696
  2. Establish Trust with KMS (Hint)
  3. Enable vSAN Encryption. DO NOT SELECT 'Erase Disks Before Use' (Hint)

You can also view hints on the VMware Technology Network Communities here:

https://communities.vmware.com/docs/DOC-37009

Modifying the On-disk format to enable vSAN-Encryption-at-rest can take quite some time in our nested Lab environment (> ~15 minutes).  Once you are finished, you do not need to wait for Encryption to be fully enabled and can safely end your lab.

 

Conclusion


Thank you for taking our Bonus Module Challenge!

You enabled Data-at-Rest vSAN Encryption with just the click of a few buttons after configuring vCenter to utilize the Key Management Server in our Lab.
