,Chapter 1 introducting vSphere
1.1 VMware ESXi


VMware vSphere 6.7 = "sphere" (group) of products

Vmware ESXI :
 type 1 hypervisor; runs the Vmkernel
 No linux-based serice console

Type 1 hypervisors = run directly on the system hardware and thus are often referred to as bare-
metal hypervisors.

Type 2 hypervisors = require a host operating system, and the host operating system provides I/O
device support and memory management.

VMware ESXi is a Type 1 bare-metal hypervisor

1.2 Vmware vCenter Server


Provides a centralized management platform and framework for ESX; hosts and their VMs based on
linux

Provides:
-VM templates
-VM customization
-rapid provisioning and deployment of VMs,
-role-based access controls(RBAC)
-fine-grained resource allocation controls
-vSphere Distributed Resource Scheduler
-vSphere High Availability
-vSphere Fault Tolerance

, Package options
vCenter Server Essentials Small ofice
vCenter Server foundation Vcenter server fuctionallity but limited hosts
vCenter Server standard Vcenter server fuctionallityr including provisioning,
management, monitoring, and automation.

1.3 VUM virtual machine update manager

Scans for updates/outdated systems and installs based on rules

1.4 VMware vSphere Client and vSphere Host Client

User interface for managing a virtual infrastructure

1.5 vSphere vMotion and storage motion

vMotion = ESX;/vCenter server feautre that allows lifemigration of virtual machines
Vmotion means the execution of a VM, relocating the CPU and memory footprint
Storage vmotion= migrates VM storage but not CPU&memory

1.6 DRS vSphere Distributed Resource Scheduler

DRS = automates vMotion operations (e.g clusters)
ANESXI cluster aggregates CPU power and memory of all hosts
DRS automates VM placement on startup and moves VM's if there is imbalance

1.7 SDRS vSphere Storage DRS

Storage DRS: balances storage capacity and performance in a cluster just like DRS, data store clusters
are used for this

1.8 SIOC /NIOC Storage/network I/O control

SIOC: assign storage priority and limits to VM's
NIOC: assign bandwith priority and limits to VM's

1.9 SBPM storage-based Policy management

VM storage profiles :assign storage requirements for a VM and its virtual disks

1.10 HA vSphere High Availability

vSphere HA: automates moving and restarting VM's that were running on an ESX; host during server
failure
this minimizes unplanned downtime because of an ESX; host failure
HA doesn’t provide failover for quest OS failure
Proactive HA: uses hardware monitoring to proactively move VM's from a host with hardware issues

1.11 FT vSphere Fault Tolerance

vSphere FT monitors a mirrored secondary VM on a separate physical host with a primary VM
Fast checkpointing technology supports FT of VM's with one to four CPU's
Automatically re-creates a secondary VM on another host if the host for the primary fails
