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.

Determining network bandwidth requirements


Bandwidth refers to the capacity of the network and is measured in either gigabits per second (Gbps) or megabits per second (Mbps). The bandwidth required is based on the amount of data transferred or the throughput required by the virtual machines. Most modern networks are capable of transferring data at 1 Gbps or 10 Gbps. Network adapters that support 40 Gbps have recently become available.

The number of physical network adapters in each host required to support a solution is dependent on the amount of bandwidth required to support virtual machine network traffic, the number of virtual switches required, and the network redundancy requirements.

From the case example in Chapter 3, The Design Factors, the following information is used to help calculate the network bandwidth requirements:

  • Cisco switches are used for network connectivity. Separate VLANs exist for management connectivity and production application connectivity.

  • No more than 20 application...
