Course Introduction
Introduction to vSphere and the Software Defined Data Center
As a vSphere administrator, you must be familiar with the components on which vSphere is based. You must also understand the following concepts: Virtualization, the role of the ESXi hypervisor in virtualization and virtual machines Fundamental vSphere components and the use of vSphere in the software-defined data center Use of vSphere clients to administer and manage vSphere environments

vCenter Server
vCenter Server helps you centrally manage multiple ESXi hosts and their virtual machines. If you do not properly deploy, configure, and manage vCenter Server Appliance, your environment might experience reduced administrative efficiency or ESXi host and virtual machine downtime.

Configuring and Managing Virtual Networks
When you configure ESXi networking properly, virtual machines can communicate with other virtual, and physical, machines. In this way, remote host management and IP-based storage operate effectively.

Configuring and Managing Virtual Storage
Understanding the available storage options helps you set up your storage according to your cost, performance, and manageability requirements. You can use shared storage for disaster recovery, high availability, and moving virtual machines between hosts.

Virtual Machine Management
Virtual machines are the foundation of your virtual infrastructure. Managing VMs effectively requires skills in creating templates and clones, modifying VMs, migrating VMs, taking snapshots, and protecting the VMs through replication and backups.

Resource Management and Monitoring
Although the VMkernel works proactively to avoid resource contention, maximizing performance requires both analysis and ongoing monitoring. Developing skills in resource management, you can dynamically reallocate resources so that you can use available capacity more efficiently.

vSphere Clusters
Most organizations rely on computer-based services like email, databases, and web-based applications. The failure of any of these services can mean lost productivity and revenue. By understanding and using vSphere HA, you can configure highly available, computer-based services, which are important for an organization to remain competitive in contemporary business environments. And by developing skills in using vSphere DRS, you can improve service levels by guaranteeing appropriate resources to virtual machines.

vSphere Lifecycle Management
Managing the life cycle of vSphere involves keeping vCenter Server and ESXi hosts up to date and integrated with other VMware and third-party solutions. To achieve these goals, you must understand how to use the new features provided by vSphere Lifecycle Manager, namely, clusterlevel management of ESXi hosts and the vCenter Server Update Planner.

About Lesson

VMFS Datastores

Learner Objectives

After completing this lesson, you should be able to meet the following objectives:

  • Create a VMFS datastore
  • Increase the size of a VMFS datastore
  • Delete a VMFS datastore

Creating a VMFS Datastore

You can create VMFS datastores on any SCSI-based storage devices that the host discovers, including Fibre Channel, iSCSI, and local storage devices.

Browsing Datastore Contents

You use the datastore file browser to manage the contents of your datastores.

About VMFS Datastores

  • A VMFS datastore primarily serves as a repository for VM files.
  • This type of datastore is optimized for storing and accessing large files, such as virtual disks and memory images of suspended VMs.
  • A VMFS datastore can have a maximum volume size of 64 TB.

Managing Overcommitted Datastores

A datastore becomes overcommitted when the total provisioned space of thin-provisioned disks is greater than the size of the datastore.

To actively monitor datastore capacity:

  • Set alarms to send notifications about:
    • Datastore disk overallocation
    • VM disk use
  • Use reporting to view space usage.

To actively manage datastore capacity:

  • Increase datastore capacity when necessary.
  • Use vSphere Storage vMotion to mitigate space use problems on a particular datastore.

Increasing the Size of VMFS Datastores

 

 

Increase a VMFS datastore’s size to give it more space or to possibly improve performance. In general, before changing your storage allocation:

  • Perform a rescan to ensure that all hosts see the most current storage.
  • Record the unique identifier of the volume that you want to expand.

To dynamically increase the size of a VMFS datastore:

  • Add an extent (LUN).
  • Expand the datastore within its extent.

Datastore Maintenance Mode

  • Before taking a datastore out of service, place the datastore in maintenance mode.
  • Before placing a datastore in maintenance mode, you must migrate all VMs (powered on and powered off) and templates to a different datastore.

 

Deleting or Unmounting a VMFS Datastore

VMFS Datastores

 

  • An unmounted datastore remains intact but cannot be seen from the hosts that you specify. It continues to appear on other hosts, where it remains mounted.
  • A deleted datastore is destroyed and disappears from all hosts that have access to it.
  • The deleted datastore permanently removes all files on the datastore.

Multipathing Algorithms

Arrays provide active-active and active-passive storage processors. Multipathing algorithms interact with these storage arrays:

 

  • vSphere offers native path selection, loadbalancing, and failover mechanisms.
  • Third-party vendors can create software for ESXi hosts to properly interact with the storage arrays.

Configuring Storage Load Balancing

VMFS Datastores

 

Path selection policies provide:

  • Scalability:
    • —Round Robin
  • Availability:
    • —Most Recently Used
    • —Fixed
