Mastering VMware vSphere 6.5

Overview of this book

VMware vSphere 6.5 provides a powerful, flexible and secure foundation for next-generation applications which helps you create an effective digital transformation. This book will be based on VMware vSphere 6.5 which empowers you to virtualize any complex application with ease. You’ll begin by getting an overview of all the products, solutions and features of the vSphere 6.5 suite, comparing the evolutions with the previous releases. Next ,you’ll design and plan a virtualization infrastructure to drive planning and performance analysis. Following this , you will be proceeding with workflow and installation of components. New network trends are also covered which will help you in optimally designing the vSphere environment. You will also learn the practices and procedures involved in configuring and managing virtual machines in a vSphere infrastructure. With vSphere 6.5, you’ll make use of significantly more powerful capabilities for patching, upgrading, and managing the configuration of the virtual environment. Next we’ll focus on specific availability and resiliency solutions in vSphere. Towards the end of the book you will get information on how to save your configuration, data and workload from your virtual infrastructure. By the end of the book you’ll learn about VMware vSphere 6.5 right from design to deployment and management.

The evolution of the storage world

Storage-related technologies have been changing really fast in recent years and flash memory is totally redefining the storage offering, both in the architectures, as described previously, and also on the effective components where data is stored.

Spinning disks

Just 10 years ago (but we could also say just a little over 5 years ago), the different tiers described previously were usually filled with the following types of storage:

  • Tier 0: 15K RPM Serial-Attached SCSI (SAS) disks
  • Tier 1: 10K RPM SAS disks
  • Tier 2: 7K RPM SATA or nearline disks
  • Tier 3: Usually tapes

Traditional Hard Disk Drives (HDD) were the standard components for storage arrays, and more were used both for redundancy and...
