vSphere 7 Foundations 7.2 - Software Defined Storage with vSAN - Configure vSAN and Witness Host

In recent years, VMware have been pushing vSAN as the modern standard for storage in virtualised platforms. In this module, you'll learn how to create and manage a vSAN, and how to move your Virtual Machines to vSAN. Glossary for Module 7 Glossary Software Defined Storage A type of storage where the placement of storage blocks is controlled by software, instead of dictated by configured hardware Hyper Converged Infrastructure (HCI) A server architecture which virtualise servers, storage and networking, using Virtualisation, Software Defined Storage and Software Defined Networking Failures to Tolerate (FTT) The number of component failures to tolerate - for example a host, disk, network adapter, etc. Dictates how vSAN must store objects to ensure the desired level of resilience Module Summary vSAN has fast become VMware’s favourite storage technology - from its humble beginnings in vSphere 5 as the vSphere Storage Appliance to the advanced software defined storage platform it is today. Whilst far from perfect, it does create a compelling case for itself. That said, designing a vSAN can be a complex process, ensuring that adequate cache is available an that the components are certified, so don’t expect exam questions to be too in depth. Most important is probably understanding how FTT affects the space a given device consumes - e.g, FTT=1 means 100GB will consume 200GB on the disk.
