Overview of this book

Amidst all the recent competition from Citrix and Microsoft, VMware's vSphere product line is still the most feature rich and futuristic product in the virtualization industry. Knowing how to install and configure vSphere components is important to give yourself a head start towards virtualization using VMware. If you want to quickly grasp the installation and configuration procedures, especially by using the new vSphere 5.1 web client, this book is for you.VMware vSphere 5.1 Cookbook will take you through all the steps required to accomplish a task with minimal reading required. Most of the tasks are accompanied with relevant screenshots with an intention to provide a visual guidance as well.The book has many useful recipes that will help you progress through the installation of VMware ESXi 5.1 and vCenter Server 5.1. You will learn to use Auto Deploy and Image Profiles to deploy stateless/stateful ESXi servers, configure failover protection for virtual machines using vSphere HA, configure automated load balancing using vSphere DRS and DPM. Finally, the book guides you through upgrading or patching ESXi servers using VMware Update Manager and also deploying and configuring vSphere Management Assistant (VMA) to be able to run scripts to manage the ESXi servers.

Preparing the vSphere network for iSCSI multipathing


iSCSI multipathing can be achieved by having two VMkernel interfaces configured with an active adapter each, but no standby adapters.

Once done, these VMkernel (vmk) interfaces should be bound to the software iSCSI adapter. This type of multipathing is needed when you use a single portal storage array such as the HP LeftHand and Dell EqualLogic.

Note

In the vSphere Storage guide, it is mentioned that a virtual machine I/O might be delayed for up to 60 seconds while path failover takes place. These delays allow the SAN to stabilize its configuration after topology changes. In general, the I/O delays might be longer on active-passive arrays and shorter on active-active arrays.

How to do it...

The following procedure will guide you through the steps required to create and configure port groups to aid in iSCSI multipathing:

  1. Create an additional VMkernel interface using the Add Networking wizard. You could follow the same instructions from the Creating...
