VMware Module 2 - Intro to vSphere and Software Defined Data Center Flashcards
What is Operating System in VMware?
A software designed to allocate physical resources to applications
What is Application in VMware?
Software that runs on an operating system, consuming physical resources
What is a Virtual Machine in VMware?
A specialized application that abstracts hardware resources into software
What is Guest in VMware?
The operating system that runs in a VM (also called the guest operating system)
What is a Hypervisor in VMware?
A specialized operating system designed to run VMs
What is a Host in VMware?
Physical computer that provides resources to the ESXi Hypervisor
What is vSphere?
A server virtualization product of VMware that combines the ESXi hyperisor and the vCenter Server management platform
What is a Cluster
A group of ESXi hosts whose resources are shared by VMs
What is vSphere vMotion?
Cluster feature that protects against host hardware failures by restarting VMs on hosts that are running normally
What is vSphere HA?
Cluster feature that protects against host hardware failures by restarting VMs on hosts that are running normally.
What is vSphere DRS
Cluster feature that uses vSphere vMotion to place VMs on hosts and ensure that each VM receives the resources that it needs.
Explain Virtual Machines
A software representation of a physical computer and its components. The virtualization software converts the physical machine and its components into files.
What is VMware Tools?
A bundle of drivers. Using these drivers, the guest operating system can interact efficiently with the guest hardware.
VMware Tools adds extra functionality so that ESXi can better manage the VMs use of physical hardware
What are Benefits of Virtual Machines
Easy to move or copy
Independent of physical hardware because VMs are encapsulated into files.
What are Four Types of Virtualization?
Server Virtualization
Network Virtualization
Storage Virtualization
Desktop Virtualization
What is Server Virtualization?
Server Virtualization allows multiple operating systems to run on a single physical server as a virtual machine. Each with access to the underlying server’s computing resources
What is a Network Virtualization?
Network virtualization is the complete reproduction of a physical network in software.
What is Storage Virtualization?
Storage Virtualization is the process of creating a software-based representation of network storage devices into what appears to be a single unit.
What is Desktop Virtualization?
A virtual desktop for end users to use
What is Software-Defined Data Center?
In SDDC, all infrastructure is virtualized and the control of the data center is automated by software. `
Explain SDDC (Software Defined Data Center) ?
SDDC is deployed with isolated computing, storage, networking and security resources that are faster than the traditional, hardware-based data center
All resources (CPU, memory, disk and network) of a software-defined data center are abstracted into files. The abstracted files bring the benefits of virtualization at all levels of infrastructure.
What are Software Define Data Center Components?
Service Management and Automation
Cloud Management Layer
Virtual Infrastructure Layer
Physical Layer
Security Layer
What is Service Management and Automation in SDDC
Use service management and automation to tract and analyze the operation of multiple data source in the multiregion SDDC.
Service Management deploys additional features like vRealize Operations/Automation/Orchestrator
What is Cloud Management Layer in SDDC?
This layer in SDDC includes the service catalog, which houses the facilities to be deployed.
This layer in SDDC also includes orchestration, which provides the workflows to deploy catalog items.
This layer in SDDC also includes portal for end users to access and use the SDDC
What is Virtual Infrastructure Layer in SDDC?
This layer in SDDC creates the virtualization platform for the hypervisor, pools of resources, and virtualization control.
What is Physical Layer in SDDC?
The lowest layer of the solution. This includes compute, storage and network components
What is Security Layer in SDDC?
Customers use this layer of the platform to meet demanding compliance requirements for virtualized workloads and to manage business risk.
What is Cloud Computing and it’s Components?
Cloud computing makes use of the efficient pooling of an on-demand, self-managed, and virtual infrastructure.
Cloud Infrastructure
IT Automation
VDI
Hybrid Cloud
What is Cloud Infrastructure in Cloud Computing?
Uses the high performance, availability and scalability of the SDDC to run mission-critical applications such as database, web applications and virtual desktop infrastructure (VDI)
What is IT Automation in Cloud Computing?
Automate infrastructure and application delivery with self-service capabilities
What is VDI in Cloud Computing?
Provides a complete solution for VDI deployment at scale.
What is Hybrid Cloud in Cloud Computing?
Build a hybrid cloud with a common infrastructure. Connects your on-premises and off-premises data center that is compatible, stretched and distrubuted
What is VMware Skyline?
Is a support technology that provides predictive analysis and proactive recommendations to help you avoid problems
What are VMware Skyline Benefits/Features?
Issue Avoidance
Shortens the time it takes to resolved a problem so that you can get back to your business quickly.
What is Skyline Health in Skyline Family?
A feature. This feature is available to all VMware customers.
Has vSphere and vSAN findings.
Supports vSphere 6.7 U1 and later
What is Skyline Advisor in Skyline Family?
Available for Production and Premier Support Customers (and upgraded version)
Supports vSphere, vSan, NSX for vSphere, vRealize Operations Manager and VMware Horizon
Supports vSphere 5.5 and later
Automates log transfers and log Assist
Uses cloud based ID and access
Difference Between Physical and Virtual Architecture?
Physical uses the components that are installed on the board.
Virtual uses components that are installed but are shared. They use the components through a thin layer called the virtualization layer or hypervisor.
What is Physical Resource Sharing?
Multiple Virtual Machines running on a physical host, share the compute, memory, network and storage resources of the host.
What is CPU virtualization?
In a physical environment, the operating system assumes the ownership of all the physical CPUs in the system. CPU virtualization emphasizes performance and runs directly on the available CPUs.
What is Virtualized Host Memory Usage?
Creates a virtual address space for applications.
The allocated memory space is configured when the VM is created and has the same properties as the virtual address space.
What is GPU Virtualization?
Virtualized Graphics.
Can be used for Virtual Desktops
Graphic Intensive applications
Can configure VMs up to four vGPU
What is vSphere 7 Bitfusion?
Page: 36
Bitfusion provides elastic infrastructure for artificial intelligence and machine learning workloads
With Bitfusion, GPUs can be shared in a way that is similar to how vSphere shares CPUs
What is VMware Host Client?
Page: 39
Is an HTML5-based user interface that you can use to manage individual ESXi hosts directly when vCenter Server is unavailable.
What is vSphere Client?
The vSphere Client is an HTML5-Based client. You manage the vSphere environment with the vSphere Client by connecting to vCenter Server Appliance
What is Power CLI?
A command-line and scripting tool that is built on Windows Powershell
- Provides a powershell interface to vSphere API
What is ESXCLI?
A tool that allows for remote management of ESXi hosts by using the ESXCLI command set
What is ESXi?
ESXi is a hypervisor that you can buy with vSphere or get in a free, downloadable version.
