VMware vSphere SDDC Private Cloud Lab

SDDC (Software Defined Data Center) is an architecture that allows for any application's infrastructure to be fully automated and always available.

It's a special kind of data storage and computing facility in which basic components such as CPU, storage, networking, security are all virtualized and delivered as services via smart software.

Main Components of VMware SDDC

  • Server Virtualization with VMware's vSphere

  • Resource Sharing with VMware vSphere HA and Storage DRS

  • Network Virtualization with VMware NSX

The objective of this project is to utilize VMware infrastructure for private cloud hosting solutions in your home lab. You'll also find relevant guides on alternative large-scale VMware deployments.

The two core components of vSphere are ESXi and vCenter Server.

ESXi is the virtualization platform to make virtual machines and virtual appliances.

The vCenter server appliance is a preconfigured virtual machine optimized for running vCenter server and the vCenter server components. vCenter server is a service that lets you pool and manage the resources of multiple hosts.


Getting Started

To ensure a successful VMware deployment, note the workflow required:

  1. Prepare for ESXi Installation.

  2. Install ESXi on Hosts.

  3. Configure ESXi on Hosts.

  4. Prepare for vCenter Installation.

  5. Deploy vCenter Server Appliance.

  6. Manage vCenter Server Services

  7. vSphere Distributed Switch Setup

  8. NFS Storage Server Setup

  9. Compute Cluster & Resource Sharing Solutions(vHA, DRS, SDRS)

  10. Provision Windows and Linux VMs to vSphere Compute Cluster

  11. NSX-T Setup and Configuration

Prepare for ESXi Installation

Two important steps to implement for preparation are:

  1. Download the ESXi Installer

Create a VMware Customer Connect account and download ESXi VMware-VMvisor-Installer.

  1. Choose option for installing ESXi

ESXi installations are designed to accommodate a range of deployment sizes.
The different options available for accessing the installation media and booting the installer:

Check this guide here to thoroughly understand the different ways of deployment.

We'll implement Interactive ESXi installation with VMware Workstation for small deployment of 3 hosts in this project.

  1. ESXi Requirements

To install or upgrade ESXi, your system must meet specific hardware and software requirements.

ESXi Hardware Requirements

To install or upgrade ESXi 7/8, your hardware and system resources must meet the following requirements:

  • Requires a host with at least two CPU cores.

  • Supports a broad range of multi-core of 64-bit x86 processors.

  • Requires the NX/XD bit to be enabled for the CPU in the BIOS.

  • Minimum of 8 GB of physical RAM. Provide at least 8 GB of RAM to run virtual machines in typical production environments.

  • For 64-bit virtual machines, support for hardware virtualization (Intel VT-x or AMD RVI) must be enabled on x64 CPUs.

  • Recommended size for VMware ESXi 7/8 is 142GB minimum. VMFS datastore is created automatically to store virtual machine data. Local disk of 128 GB or larger for optimal support of ESX-OSData. The disk contains the boot partition, ESX-OSData volume and a VMFS datastore.

  • vSphere 7/8 supports booting ESXi hosts from the Unified Extensible Firmware Interface (UEFI). With UEFI, we can boot systems from hard drives, CD-ROM drives, or USB media.

For a complete list of supported processors and server platforms, see the VMware compatibility guide at http://www.vmware.com/resources/compatibility.


Install ESXi on Hosts

Creating ESXi virtual machine in VMware Workstation

  1. Download VMware Workstation Player 17 here

  2. Open your VMware Workstation, click on Create a New Virtual Machine

  3. Select Installer disc image file (iso): and click Browse... to find the VMware ESXi iso in your directory. Click Next.

  4. Name the virtual machine as ESXi-1 and select Location you want the ESXi installed. Click Next.

  5. Select store virtual disk as a single file and specify disk capacity of 180GB. Click Next.

  6. Click on Customize Hardware, select Memory size of 8GB and 4 Processor cores as minimum.

    Select Virtualize Intel VT-x/EPT or AMD-V/RVI

    Use Bridged or NAT network connection.

  7. Select Power on this virtual machine after creation.

    Click Finish.

Installing ESXi in VMware Workstation

Once your virtual machine is up and running, follow the next steps to finish the ESXi installation on your VMware Workstation.

  1. When the Welcome to the VMware ESXi installation pops up, press Enter to continue.

  2. Accept the End User License Agreement by hitting the F11 key.

  3. Select the Local disk where ESXi will be installed and hit Enter.

  4. Choose your keyboard layout and hit Enter.

  5. Enter your Root password, confirm it and securely store it. Press Enter.

  6. Confirm the installation by pressing F11.

  7. Once complete, you must remove the installation media. You can remove it by clicking I Finished Installing at the bottom right side of the VMware Workstation window.

After removing your installation media, go back to the virtual machine installation screen and hit Enter to reboot. The VM will shutdown and reboot.


Configure ESXi on Hosts

After the reboot is complete and the ESXi virtual machine is running, note the IP address of the ESXi host server. Dynamic host configuration protocol (DHCP) assigns the IP address the VMware ESXi server uses when it is initialized.

You can use the IP address assigned from DHCP, or as an alternative, you can set up a static IP address of your choice by following these steps.

  1. In the running ESXi virtual machine, press F2.

  2. Enter your Login Name as root, type your Password and hit Enter.

  3. Use the arrow keys to move and select Configure Management Network then press Enter.

  4. Select IPv4 Configuration and hit Enter.

  5. Using the arrow keys, highlight Set static IPv4 address and network configuration and press the Space key to select it.

  6. Enter your static IPv4 Address and Subnet Mask, and hit Enter. Note Default Gateway will have the same IPv4 address as Primary DNS Server. Please note you'll have to confirm the static IPv4 address is available, you can ping it and confirm it's Unreachable at this moment.

  7. Navigate to DNS Configuration and press Enter.

  8. Next, select Use the following DNS server address and hostname and press the Space key.

  9. Insert your DNS server IPv4 address, change Hostname to esxi01 and hit Enter.

  10. Use the ESC key to go one step back and afterward hit the Y`` key to save changes and restart network management.

  11. Go back to Test Management Network to ping your default gateway and DNS servers.

  12. Confirm the Ping Address and press Enter. Note hostname resolved to 'localhost.localdomain`.

  13. To log out, hit the ESC key and press the F12 key.

  14. Finally, run the ESXi virtual machine from the VMware Workstation. After the server is up and running, navigate in your browser to the ESXi server's IPv4 address and you can start managing your VMware ESXi vSphere server.

We're installing and configuring three ESXi hosts, hence you'll have to repeat the Interactive Installation Step twice to get total of three ESXi hosts powered on and running.

Also note when you're configuring subsequent ESXi, remember to change the Hostname in DNS Configuration section. For example second and third ESXi will be named esxi02 and esxi03 respectively.

Please note the hardware specifications for esxi02 will be different and bigger than other hosts because we'll deploy the vcsa on it.


Deploy vCenter Server Appliance

You can deploy the vCenter Server appliance on an ESXi host 7/8, or on a vCenter Server instance 7/8.

When you use Fully Qualified Domain Names, verify that the client machine from which you are deploying the appliance and the network on which you are deploying the appliance use the same DNS server.

There are two methods of deploying VCSA

  • Deploy a vCenter Server Appliance by Using the CLI
  • Deploy a vCenter Server Appliance by Using the GUI

We'll implement the CLI method.

Requirements for Deploying the vCenter Server Appliance

Our system must meet specific software and hardware requirements.

Prerequisistes

  1. Download the vCenter Installer from Customer Connect account

  2. Hardware requirements of ESXi Host:

    This depends on the hardware specifications of host esxi02.

    • We'll use Tiny Environment(for up to 10 hosts or 100 virtual machines)
    • 18GB Memory (14GB minimum)
    • Default storage size of 579GB minimum

    Software requirements:

    • Assign a fixed IP address and an FQDN that is resolvable by a DNS server so that clients can reliably access the service.
    • If you use DHCP instead of a static IP address for the vCenter Server appliance, verify that the appliance name is updated in the domain name service (DNS).
    • If you manage network components from outside a firewall, you might be required to reconfigure the firewall to allow access on the appropriate ports. For the list of all supported ports and protocols in vSphere, see the VMware Ports and Protocols Tool

vSphere Client Software Requirements

Use of the vSphere Client requires supported web browsers:

  • Google Chrome 89 or later
  • Mozilla Firefox 80 or later
  • Microsoft Edge 90 or later

Supported Guest Operating Systems

  • Windows 32-bit and 64-bit
  • Mac OS

Running the vCenter Server Appliance Installer

  1. Navigate to your root directory and extract contents of the VMware-VCSA iso file downloaded from VMware Customer Connect account. In my case, the root directory is C:\ directory on my Windows local machine.

  2. To find the command line tool(Installer), navigate to the vcsa-cli-installer subdirectory in the extracted folder of downloaded VMware-VCSA iso file.

  • If you are running the deployment on Windows OS, executable is located at vcsa-cli-installer\win32\vcsa-deploy.exe
  • If you are running the deployment on Linux OS, executable is located at vcsa-cli-installer/lin64/vcsa-deploy
  • If you are running the deployment on Mac OS, executable is located at vcsa-cli-installer/mac/vcsa-deploy
  1. Use the vcsa-cli-installer\templates\install\embedded_vCSA_on_ESXi.json template to deploy single instance of VCSA on our second ESXi host.

Edit the template file for your specification. View sample below:

Disabling firewall(optional)

If firewall is configured to block nfs related ports. Please re-open this ports. No need to disable entire firewall.

Mount NFS Shares to ESXi Hosts

We'll use vCenter server to mount this NFS shares to ESXi hosts in workload cluster named `odennav-dc-cluster. This task will be implemented with terraform.

yum update -y
yum install net-tools

View IP address of NFS server

ifconfig

We'll add the IPv4 address of NFS servers to the terraform manifest vmware-sddc-private-cloud/terraform-manifest/modules/datastores_nfs/datastores_nfs_main.tf

Please note you'll have to create another NFS server to provide redundancy and fault tolerance. If one NFS server goes down or experiences issues, clients can still access data from the other NFS server.

Name of directories to mount as nfs shares:

  • /nfs-share-2
  • /hb-share-2

For the second NFS server, use same disk sizes for 1st NFS server.


Compute Cluster & Resource Sharing Solutions(vHA, DRS, SDRS)

High Availability is a utility that provides uniform, cost-effective failover protection against hardware and operating system outages within your virtualized IT environment.

vSphere HA allows you to:

  • Monitor VMware vSphere hosts and virtual machines to detect hardware and guest operating system failures.

  • Restart virtual machines on other vSphere hosts in the cluster without manual intervention when a server outage is detected.

  • Reduce application downtime by automatically restarting virtual machines upon detection of an operating system failure.

VMware vSphere Distributed Resource Scheduler (DRS) is the resource scheduling and load balancing solution for vSphere. DRS works on a cluster of ESXi hosts and provides resource management capabilities like load balancing and virtual machine (VM) placement.

Storage DRS allows you to manage the aggregated resources of a datastore cluster. When Storage DRS is enabled, it provides recommendations for virtual machine disk placement and migration to balance space and I/O resources across the datastores in the datastore cluster.

We'll implement the following to enable this solutions in vSphere using Terraform:

  • Install Terraform
  • Create Datacenter
  • Provision Datacenter cluster and add ESXi hosts
  • Create Datastore cluster
  • Enable vHA, DRS and SDRS
  • Add NFS shares to Datastore Cluster
  • Create Inventory tags

NSX-T Setup and Configuration

NSX network virtualization programmatically creates and manages virtual networks.

Using network virtualization, the functional equivalent of a network hypervisor we can reproduce the complete set of Layer 2 through Layer 7 networking services (for example, switching, routing, access control, firewalling, QoS) in software.

NSX works by implementing three separate but integrated planes: management, control and data planes

These planes are implemented as a set of processes, modules, and agents residing on two types of nodes:

  • NSX Manager
  • Transport Nodes.

Requirements

Note the following resources we'll need to configure NSX-T for this project:

  • Two datacenter clusters:

    Workload cluster(3 ESXi hosts)

    Edge cluster(1 ESXi host)

  • vDS(Virtual Distributed Switch) over workload cluster, With six port-groups available for:

    • Management
    • vMotion
    • Provisioning
    • Fault tolerance
    • Tunnel Endpoint
    • NSX Edge(Uplink)
  • Enable Jumbo frames by setting MTU to 1700 or larger on VSS(Virtual Standard Switch) and VDS.

  • Use physical multilayer switch and configure 3 VLANS:

    Mangaement VLAN Tunnel Endpoint(TEP) NSX Edge VLAN

    These VLANS should be trunked(802.1q) to the ESXi hosts in workload cluster so that they're used with virtual switches.

  • NSX-T Data Center needs license for proper configuration and vSphere7 Enterprise Plus license needed for ESXi hosts.

Deploy NSX-T Manager

NSX-T Manager supports a cluster with three node, which merges policy manager, management, and central control services on a cluster of nodes.

Clustering is recommended for production environment and this provides high availability of the user interface and API.

Download VMware ovf tool for your preferred operating system from here and use it to deploy to an ESXi host.

Due to resources available we'll just install one manager on esxi03 which is managed by vCenter.

Procedure

Run the ovftool command with appropriate command parameters. Installation is done on windows local machine

Ceate directory on local machine for ovftool logs

mkdir C:\ovftool-logs

Extract ovftool zipped package to C:\ and run below command in Windows command prompt. Note my extracted folder from zip package is C:\VMware-ovftool-4.4.3-18663434-win.x86_64

After deployment, verify that the NSX Manager UI comes up by accessing the following URL, 192.168.10.15 on your browser.

NSX IP-Pools Setup

We'll setup IP pools to assign Tunnel Endpoints to each of our ESXi hosts that are participating in the NSX Overlay networks.

Since we're using three hosts, and expect to deploy 1 edge node, we’ll need a TEP Pool(static IPv4 addresses) with at least 4 IP Addresses.

Procedure

Login to NSX Manager

At the NSX-T Manager, go to Networking -> IP Management -> IP Address Pools

  • Click ADD IP ADDRESS POOL enter the following details:

    Name --> TEP-Pool

    Description --> Tunnel Endpoint Pool

  • Click Set hyperlink under Subnets.

On the Set Subnets section, assign the following:

IP Ranges -----> 192.168.20.2-192.168.20.30

CIDR ----------> 192.168.20.0/24

Gateway IP ----> 192.168.20.1

DNS Servers ---> 192.168.36.2

DNS Suffix ----> odennav.local

Click ADD

NSX Transport Zone Setup

Next task is to setup transport zone where data packets are sent between nodes.

The ESXi hosts that participate in NSX networks are grouped in the transport zone.

We'll setup two transport zones:

  • Overlay Transport Zones

  • VLAN Transport Zones

Procedure for Overlay Transport Zones

At the NSX-T Manager, go to System –> Fabric –> Transport Zones

Click the + button and assign the the following:

Name ----------> Overlay-Zone

Description ---> NSX Overlay Zone

Switch Name --->

Traffic Type --> Overlay

Press ADD

Procedure for VLAN Transport Zones

At the NSX-T Manager, go to System –> Fabric –> Transport Zones

Click the + button and assign the the following:

Name ----------> VLAN-Zone

Description ---> VLAN Transport Zone

Switch Name ---> NSX-VLAN

Traffic Type --> Overlay

Click ADD to save this configuration

Procedure for Uplink Profiles

This helps to set uplinks for any of the transport nodes we’ll be creating.

We'll use two NICs(Network Interface Cards)

At the NSX-T Manager, go to System –> Fabric –> Profiles

Click on Uplink Profiles then press the + button and assign the the following:

Name -------------> Overlay-Uplink-Profile

Transport VLAN ---> 20

Save this configuration

Procedure for Transport Node Profile

This is used to provide configuration for each of the ESXi nodes and specify which NICs on the nodes to be configured for the VDS switch.

It also specifies the IP Addresses assigned for the TEP(Tunnel Endpoints) on this switch.

We'll use two NICs(Network Interface Cards)

At the NSX-T Manager, go to System –> Fabric –> Profiles

Click Transport Node Profiles then press the + button and assign the the following:

Name --------------> Transport-Node-Profile

Description -------> Odennav Transport Node Profile

Type --------------> VDS

Mode --------------> Standard

Name --------------> vcenter.odennav.local && Switch -----> Odennav-DSwitch

Transport Zone ----> Overlay-Zone

Uplink Profile ----> Overlay-Uplink-Profile

IP Assignment -----> Use IP Pool

IP Pool -----------> TEP-Pool

Uplinks -----------> vmnic1(Uplink 1)

Save this configuration.

Procedure to Configure Transport Nodes

We apply the transport node profile to configure the transport nodes in the odennav-dc-cluster

At the NSX-T Manager, go to System –> Fabric –> Nodes

Click Host Transport Nodes then press the Managed by button to select the vCenter server.

Select radio button to indicate the chosen workload cluster

Then click on CONFIGURE NSX and assign the following:

Transport Node Profile ---> Transport-Node-Profile

Click APPLY to configure the ESXi hosts.

Now we've successfully configured our chosen transport nodes and uplinks on vDS with the profiles created.

Deploy NSX Edge Nodes

NSX-T Edge nodes are used for security and gateway services that can’t be run on the distributed routers in use by NSX-T. North/South routing and load balancing services are implemented by edge nodes.

Edge node is deployed to Edge Cluster named odennav-edge-cluster. This approach is best for production setup because these nodes will become a network hotspot.

The Edge VM has a virtual switch inside it, and we’ll connect the edge vm uplinks to the Distributed virtual switch uplinks.

Edge VM will have three or more interfaces:

  • Management
  • Overlay
  • VLAN traffic to the physical network.

Procedure

  • In NSX Manager, go to System > Fabric > Nodes > Edge Transport Nodes.

  • Click Add Edge Node.

Assign the following:

Name -------------------> Edge-1

Host name --------------> edge1.odennav.local

Form Factor ------------> Select the appropriate edge node size.

CLI User Name ----------> admin

CLI Password -----------> ***********

Allow SSH Login --------> Select option based on your datacenter policy.

System Root Password----> **************

Allow Root SSH Login ---> Select option based on your datacenter policy.

Audit User Name --------> audit

Audit Password --------> ********

Compute Manager --------> vcenter

Cluster ----------------> odennav-edge-cluster

Host -------------------> 192.168.10.14

Datastore --------------> nfs-datastore-2

IP Assignment ----------> Static

Management IP ----------> 192.168.10.17

Default Gateway --------> 192.168.10.1

Management Interface ---> DPortGroup-MGMT

DNS Servers ------------> 192.168.36.2

NTP Servers ------------> pool.ntp.org

Edge Switch name -------> nsx-overlay, nsx-vlan

Transport Zone ---------> nsx-overlay-transportzone, nsx-vlan-transport-zone

Uplink Profile ---------> Overlay-Uplink-Profile

Teaming Policy(Uplinks)-> DPortGroup-TEP(uplink-1), DPortGroup-EDGE(uplink-1)

IP Assignment ----------> Use Static IP List

Static IP List ---------> 192.168.20.17

Gateway ----------------> 192.168.20.1

Subnet Mask ------------> 255.255.255.0

Wait until the Configuration State column displays Success.

You can click the Refresh button to refresh the window.

Repeat steps 4-6 to deploy Edge-2 on host 192.168.10.12 with management IP 192.168.10.18 and static IP 192.168.20.18.

Create an Edge Cluster

Procedure

VMware recommend deployment of edge nodes in pairs and pooled together to form an edge cluster.

  • In NSX Manager, go to System > Fabric > Nodes > Edge Clusters.

  • Click Add Edge Cluster.

Assign the following:

Name ----------------> Edge-cluster-1

Description ---------> Odennav Edge Cluster

  • Move Edge-1 and Edge-2 from the Available window to the Selected window.

  • Save this configuration.

Next, we create overlay networks for our VMs.


Create Tier-1 Gateways

We'll setup two tier-1 gateways/routers for nsx overlay segments

In NSX Manager, go to Networking > Tier-1 Gateways.

Click Add Tier-1 Gateway.

Assign the following:

Tier-1 Gateway Name --------> T1-gateway-1

Edge Cluster ---------------> Edge-cluster-1

Linked Tier-0 Gateway ------> T0-gateway-1

Under Route Advertisement, enable the following:

All Connected Segments & Service Ports All Static Routes All IPSec Local Endpoints

Save the changes.

Repeat steps 2-5 and create T1-gateway-2. Specify the same edge cluster.

Create NSX Overlay Segments for VMs

We'll create three nsx overlay segments for VMs

In NSX Manager, go to Networking > Segments.

Click Add Segment.

Assign the following:

Segment Name --------> LB1.1

Connectivity --------> T1-gateway-1

Transport Zone ------> Overlay-Zone

Subnet --------------> 192.168.1.0/24

Repeat steps 2-3 and create WEB1.1 (subnet: 192.168.2.0/24, connectivity: T1-gateway-2)

Verify that LB1.1 and WEB1.1 are created under the VDS(Odennav-DSwitch) in Vcenter.

Create NSX VLAN Segment

We'll create a segment for our Tier-0 gateway to use and connect to our physical network.

In NSX Manager, go to Networking > Segments.

Click Add Segment.

Assign the following:

Segment Name --------> Uplink-Segment

Connectivity --------> T0-gateway-1

Transport Zone ------> VLAN-Zone

Subnet --------------> 192.168.50.2/24

VLAN ----------------> 50


Create a Tier-0 Gateway

This gateway connects directly to our physical VLAN and provides north/south routing into the NSX overlay networks.

With the Tier-0 Gateway we can connect our new NSX backed overlay segments to the physical network through the NSX-T Edge cluster.

Procedure

  • In NSX Manager, go to Networking > Tier-0 Gateways.

  • Click Add Tier-0 Gateway.

  • Enter a name for the gateway, for example, T0-gateway-1.

  • Select the HA (high availability) mode Active Standby.

  • Select the Edge cluster Edge-Cluster-1.

  • Click Save and continue configuring this gateway.

  • Click Interfaces and click Set.

  • Click Add Interface.

  • Enter a name, for example, IP1-EdgeNode1.

  • Enter the IP address 192.168.50.11/24.

  • In the Connected To (Segment) field, select Uplink-segment-1.

  • In the Edge Node field, select Edge-1.

  • Save the changes.

  • Repeat steps 8-13 to configure a second interface called IP2-EdgeNode2. The IP address should be 192.168.50.12/24. The Edge Node should be Edge-2.

  • In the HA VIP Configuration field, click Set to create a virtual IP for the tier-0 gateway.

  • Enter the IP address 192.168.50.13/24.

  • Select the interfaces IP1-EdgeNode1 and IP2-EdgeNode2.

  • Save the changes.

Configure Routing on the Physical Router and Tier-0 Gateway

Procedure

  • On the physical router, configure a static route to the subnets 192.168.1.0/24 and 192.168.2.0/24 via 192.168.50.13, which is the virtual IP address of the tier-0 gateway's external interface.

  • In NSX Manager, go to Networking > Tier-0 Gateways.

  • Edit T0-gateway-1.

  • Under Routing > Static Routes, click Set and click Add Static Route.

  • In the Name field, enter default.

  • In the Network field, enter 0.0.0.0/0.

  • Click Set Next Hops.

  • In the IP Address field, enter 192.168.50.1.

  • Click Add.

  • Save the changes.

Finally, we've deployed Tier-0 router and connected NSX-T backed overlay segments to your physical network.

Implement the following to test east-west and north-south connectivity:

  • Ping WEB-VM-1 from LB-VM-1 and vice versa
  • Ping the downlink interface of the physical router from WEB-VM-1.

Please note for VMs deployed to NSX-T overlay segments, ensure the network adapter is set to correct overlay segment.
