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.

Using jumbo frames


Enabling jumbo frames on the networks used for vMotion or IP Storage can increase performance and throughput. When jumbo frames are configured, iSCSI or NFS packets can be transferred over the network in a single frame; there is no fragmentation. This decreases the amount of CPU overhead required to encapsulate and de-encapsulate IP storage packets.

How to do it…

  1. Determine use cases to enable jumbo frames.

  2. Configure jumbo frames on virtual switches.

  3. Configure jumbo frames on VMkernel ports.

  4. Ensure jumbo frames are configured end to end on the physical network: physical switches and array network interfaces.

  5. Test the network for proper end-to-end jumbo frames configuration.

How it works…

Jumbo frames must be supported and enabled on the network from end to end; this includes the physical network infrastructure as well. In vSphere, jumbo frames are enabled either in the vSwitch configuration or on the vDSwitch uplinks by setting the Maximum Transmission Unit (MTU) value to 9000...
