VMware vSphere 6.x Datacenter Design Cookbook - Second Edition

Overview of this book

VMware is the industry leader in data center virtualization. The vSphere 6.x suite of products provides a robust and resilient platform to virtualize server and application workloads. With the release of 6.x a whole range of new features has come along such as ESXi Security enhancements, fault tolerance, high availability enhancements, and virtual volumes, thus simplifying the secure management of resources, the availability of applications, and performance enhancements of workloads deployed in the virtualized datacenter. This book provides recipes to create a virtual datacenter design using the features of vSphere 6.x by guiding you through the process of identifying the design factors and applying them to the logical and physical design process. You’ll follow steps that walk you through the design process from beginning to end, right from the discovery process to creating the conceptual design; calculating the resource requirements of the logical storage, compute, and network design; mapping the logical requirements to a physical design; security design; and finally creating the design documentation. The recipes in this book provide guidance on making design decisions to ensure the successful creation, and ultimately the successful implementation, of a VMware vSphere 6.x virtual data center design.

Leveraging host flash


Virtual Flash enables the use of Solid State Disks (SSD) or PCIe-based flash storage in ESXi hosts in order to accelerate the performance of virtual machines by providing read caching and host swapping.

How to do it…

  1. Configure local SSDs or flash devices as Virtual Flash Resource.

  2. Configure vSphere Flash Read Cache (vFRC) for virtual machine disks.

  3. Allocate Virtual Flash capacity for the host swap cache.

How it works…

Configuring local SSDs for use as Virtual Flash Resource is done from ESXi host settings, the Virtual Flash Resource Management menu. Adding the capacity will display the flash device that is eligible to be used as Virtual Flash Resource, as shown in the following screenshot:

Flash devices selected as virtual flash cache are formatted with Virtual Flash File System (VFFS), and the capacity can only be used for Virtual Flash Resource.

Once the flash capacity has been added, virtual machines are configured to consume the Virtual Flash Resource as vSphere Flash Read...
