By Keith Barker
1. Welcome to VMware vSphere Data Center Virtualization (00:03:05)
Welcome to the course! In this Nugget, Keith shares some tips to assist you in getting the most from this course.
2. The Hype about Hypervisors (00:33:25)
In this Nugget, Keith discusses and demonstrates installing Virtual Machines (VMs) on a Type-1 hypervisor (using VMware ESXi), and a Type-2 hypervisor (using VMware Workstation).
Hands-on practice is strongly suggested to assist you with the mastery of the topics covered in this course. The free download of ESXi 5.5 and the evaluation version of VMware Workstation 10 (from www.VMware.com), as well as the free Android ISO from sourceforge.net, are software you can use to practice what is demonstrated in this video.
3. A Dream within a Dream (00:35:53)
The opportunity exists to nest our Virtual Machines (VMs) inside of other VMs. This means we can have one VM environment such as VMware Workstation acting as a hypervisor for a second virtual environment such as ESXi and other vSphere devices. The benefits of doing this in a LAB-ONLY test environment are the significant reductions in both the quantity and compatibility of hardware required for the practice lab. A topology diagram is included as part of the NuggetLab files for this course.
4. OVF & OVA (00:30:48)
Open Virtualization Format is a sweet way to export a Virtual Machine (along with its drives and details). The use of OVF Templates makes the exporting and importing of VMs very clean and easy. In this Nugget, Keith demonstrates how to create a VM, export it using an OVF Template, and then create a new second VM using the previously exported template.
The OVF for the DSL Linux demonstrated in this video is available as part of the NuggetLab files for this course.
5. Standard vSwitch Introduction (00:31:02)
The built-in virtual switch (vSwitch) in an ESXi host provides the connectivity between VMs and the outside physical world. In this Nugget, Keith introduces the core concepts regarding the standard layer 2 vSwitch.
6. Standard vSwitch Configuration (00:42:44)
In this Nugget, Keith walks you through the creation/configuration of a vSwitch, VM Port Groups, Uplinks/vmnics, and implementing fault tolerance for the VMkernel Port used for management of the ESXi host. You are encouraged to practice what is demonstrated in the video. The previous videos walk through the steps of setting up your own personal lab. Your hands-on practice will assist you in your mastery of VMware vSphere.
7. VLANs and Trunking (00:37:00)
Using VLANs can provide network isolation on a standard vSwitch as well as physical switches. In this Nugget, Keith walks you through the fundamentals of VLANs and 802.1Q trunking and then applies those concepts within vSphere on a standard switch. There are NuggetLab files are associated with this video.
8. Adding GNS3 to the vSphere Lab (00:20:13)
If you are an IOS and GNS3 enthusiast, this Nugget was made especially for you. In this video, Keith describes the logic and components for using GNS3 virtual routers within the vSphere lab for DHCP and routing functions for the VLANs we created in the previous video. The relevant IOS router configuration commands are included in the NuggetLab files for this course.
For a more detailed dive into GNS3, please see the GNS3 course here at CBT Nuggets. For training specifically about Cisco IOS, check out our ICND1/ICND2 (CCNA) courses.
9. Home Sweet Home (00:12:36)
A Windows server 2012 will be the "home" for our vCenter services. In this Nugget, Keith shares with you the details for the VMware Workstation hosted 2012 server (that will be running as a VM). You are encouraged to build the LAB environment so that you can get the hands-on practice as you and Keith enjoy these videos together.
10. vCenter Install (00:18:11)
What do VMware's SSO, inventory, and web and server services have to do with vSphere? They are the four components that make up vCenter, the centralized management and monitoring system for ESXi hosts. In this Nugget, Keith demonstrates the installation of vSphere on the 2012 server that was discussed in the previous video. Evaluations of ESXi and vCenter can be requested and downloaded directly from VMware's web site.
11. Add EXSi hosts to vCenter (00:23:12)
This Nugget introduces the use of the Web vSphere client, along wth vCenter, to bring in and centrally manage ESXi hosts.
12. vCenter AA (00:21:52)
Authentication using vCenter's Single Sign On (SSO) and Authorization using "Roles" are key ingredients for allowing administrators to get access and do their jobs in vCenter. In this Nugget, Keith explains and demonstrates setting up both Authentication and Authorization.
13. vCenter Virtual Appliance (00:23:52)
For environments that want an alternative to installing vCenter on a Windows server platform, there is a SUSE Linux-based self-contained .OVA that has all the vCenter components, and can be deployed as a virtual machine. In this Nugget, Keith demonstrates how to install, configure, and begin using the vCenter appliance to manage ESXi hosts.
14. iSCSI SAN Appliance (00:33:20)
Storage Area Networking (SAN) is best practice and a common method for the datastores used by ESXi hosts. In this Nugget, Keith discusses and demonstrates setting up "openfiler," which is a free and open source iSCSI target that can be used as part of the lab.
15. 10 Gig (the hard way) (00:28:16)
Virtual and physical networks benefit by separation of traffic and dedicated networks for management and storage. In this Nugget, we prepare the VMware Workstation software to allocate 10 1 Gig interfaces to each of the ESXi hosts. The file "Ports, IPs, and Settings for vSphere" includes the details shown in this video. The file is part of the NuggetLab files for this course.
16. iSCSI puzzle pieces (00:22:37)
iSCSI mutipathing using a software-based Host Bus Adapter (HBA) requires configuration of networking and storage in the ESXi host. In this Nugget, Keith talks about the components needed, how they are configured, and how they interact with each other. This video prepares for the next video, which focuses on the implementation and testing of the iSCSI network storage.
17. iSCSI HBA configuration (00:34:33)
In this Nugget, Keith walks you through the step-by-step process for configuring the details in the ESXi host (including the vSwitch, iSCSI HBA, VMNICs/uplinks, VMkernel ports, IP addresses, and more). The NuggetLab files associated with this course include a document, "Ports IPs and Settings," that details the IP addresses and other settings used as part of the demonstrations in this video.
18. Datastore Adds and Changes (00:23:01)
In this Nugget, Keith walks you through the steps of renaming, deleting, creating, and expanding an iSCSI-based Datastore.
19. NFS Datastore (00:14:45)
Got NFS? Turn it into a Datastore that can be used by ESXi hosts. In this Nugget, Keith demonstrates how to enable NFS shares on the openfiler appliance, followed by creating a VMware Datastore that uses the NFS share.
20. Templates and Clones (00:19:42)
Wouldn't it be great to be able to save the "perfect" VM, and replicate it over and over when needed? Templates can act as a master image for that exact purpose. In this Nugget, Keith walks you through how to create a new template, create VMs from that template, and how to clone a running VM to make a second VM based on the original. The OVA used in this video is available as part of the NuggetLab files associated with this course.
21. Distributed Switch Fundamentals (00:59:04)
Configuring the details, including multiple VM port groups on each individual standard switch, can be tedious and prone to errors. Using the concept of a Distributed Switch, a new switch that all the ESXi hosts can use, but is centrally manageable, can assist us in consistently named port groups across multiple ESXi hosts (which will be important to for vMotion to be successful). In this Nugget, Keith teaches you about the concept of a virtual Distributed Switch (VDS) and walks you through the creation, configuration, and migration of ESXi hosts to use the new switch.
22. Distributed vSwitch Features (00:46:59)
The virtual Distributed Switch (VDS) has a boatload of features, and in this Nugget, Keith walks you through what those are and how to configure them.
23. vMotion Fundamentals (00:28:35)
In this Nugget, Keith explains how vMotion works, and walks you through preparing the vSphere networking to support it.
24. vMotion in Motion (00:23:01)
In thisNugget, Keith demonstrates using vMotion and storage vMotion to move the state and storage of VMs between ESXi hosts and datastores.
25. Distributed Resource Scheduler (00:18:01)
DSR allows an automated vMotion to move VMs from ESXi hosts with a high CPU utilization, moving them to a less utilized ESXi host to more evenly redistribute the load across all the ESXi hosts in the cluster. In this Nugget, Keith demonstrates how to set up the cluster and verify that DSR is working.
26. Affinity (00:24:46)
Distributed Resource Scheduler (DRS) also can include rules we define when making decisions about which ESXi host a VM should be running on. In this Nugget, Keith explains the topic and reinforces the concept of affinity by implementing several rules and verifying to see that DRS followed those rules.
27. Snapshots and VM files (00:24:02)
Creating a snapshot in time is a handy feature that VMware does very well. In this Nugget, Keith talks with you about the files involved that make up a VM, including the extra snapshot related files. The VM files example document referred to in this video is available as part of the NuggetLab files for this course.
28. VM Memory & CPU controls (00:39:39)
Reservations, limits, and shares are methods to control the CPU and Memory allocated to each of our VMs. In this Nugget, Keith explains and demonstrates how this can be applied directly to a VM as part of its settings.
29. Resource Pools (00:29:17)
Resource Pools allow additional controls over CPU and memory using reservations, limits, and shares at the pool level. In this Nugget, Keith describes and demonstrates using these pools in a vSphere environment.
30. vApps (00:16:27)
Setting up resource pools and configuring VMs to start or stop together can be done by including those VMs into a vCenter container object called a vApp. In this Nugget, Keith explains and demonstrates creating and working with vApps.
31. VM High Availability (HA) (00:24:04)
High Availability allows detection of a failed ESXi host within a cluster, and subsequently restarting the VMs on other ESXi hosts in that cluster. In this Nugget, Keith explains and demonstrates HA within vSphere.
32. VM Fault Tolerance (FT) (00:19:11)
Running a backup instance of a VM is how Fault Tolerance (FT) for a VM is done in vSphere. In this Nugget, Keith discusses and demonstrates VM FT.
33. VM Customization (00:16:14)
Deploying customized VMs that are cloned or from a template can be done by using customization specifications inside of vCenter. In this Nugget, Keith demonstrates how to add sysprep files for older versions of windows, to create customization specs, and use them in a deployment of a new VM.
34. VM Storage Policies (00:27:05)
By categorizing Datastores, we can associate the VMs with a policy to use a Datastore that meets the needs of that VM. In this Nugget, Keith describes and demonstrates the creation, use, and validation of storage policies.
35. Storage DRS (00:34:09)
Is it possible to automate the placement and storage of our VM configuration and hard disk files? Storage DRS says "I'll do it!" In this Nugget, Keith explains how Datastore Clusters operate and demonstrates their configuration and verification, including using Storage IO control input that can influence the selection process done by Storage DRS.
36. Custom Alarms (00:19:23)
Setting an early warning system for the resources that are most critical to you can be done by creating and using custom alarms. In this Nugget, Keith demonstrates the set up and verification of a custom alarm.
37. Operations Manager (00:31:43)
vCenter Operations Manager, often referred to as "vCops," is a vApp that can look at all the data from a vCenter server and assist with sorting through it and bring attention to the administrators of vSphere - regarding the health, risk and efficiency of our virtual environment.
38. Performance and Troubleshooting (00:30:24)
Building a lab is one of the BEST WAYS EVER to become good at troubleshooting, which is one of the reasons Keith has encouraged you to build your own lab and practice what you see in these videos. This video addresses several items related to performance and troubleshooting.
39. ESXi Shell and CLI (00:19:37)
There is a Command Line Interface (CLI) option to work with our hosts via the ESXi shell. In this Nugget, Keith walks you through a couple of ways to enable it, with some examples of tools that may be used at the command line, including esxtop.
40. Additional features and products (00:28:41)
In this wrap-up Nugget, Keith talks to you about additional features and products that can be used in a vSphere virtual infrastructure. A future v6 update course will include additional details and demonstrations of many topics introduced in this video. We look forward to seeing you there!
