Vmware Server & Workstation

 

===========================
Chapter 1 Intro to VMWARE?
===========================

1) VMWARE Server & Workstation Model:

VM1                VM2                VM3
VIRTUALIZATION SOFTWARE
HOST OPERATING SYSTEM
            HARDWARE
2) VMWARE ESX Server Model:

VM1                VM2                VM3
VIRTUALIZATION SOFTWARE
            HARDWARE

==================================
Hardware Virtualization:
AMD - V
Intel Virtualization Technology (VT)
==================================
Built in OS virtualization as Hypervisor like new MS Products.

Products:

Vmware Player
Vmware Worksatation
Vmware Server
Vmware Infrastructure
Virtual Iron challenger Vmware ESX
Parallels for MAC OS
Vmware Fusion for MAC OS
Linux XEN Open Source

Vmware Worksatation VS Vmware Server
Free                                    Snapshot Manager           
Web console                    Movie Capture
Run as a Service
64GB RAMs of VMs
Run on Server OS            Run on Worksation OS

VM Ware Specifications provided to the operating system(s):

Same processor that is of host processor.
1 Virtual Processor on a host with one or more logical processors.
2 Virtual processors on a host with at leas 2 logocal processors.
3.6 GB on host memory
Maximum Memory 4 GB total available for all virtual machines.
IDE 4 Devices 950 MAX
SCSI 7 devices 950 GB Max
2 Floppy Drives
4 Serial Com ports
2 USB 1.1
3 Virtual Ethernet Card.
9 or more virtual ethernet switches.

Chapter -2 Planning for deployment. ===========================

Senario - Amy's Cake House

List of systems to be virtualized:

System 1 - Physical to Virtual env P2V runs "Cake App"
System 2- Implementing Win 2008 with file print and email on it.
System 3 - Linux Web Server
System 4 - DC/DHCP/DNS Server for AD Domain.

Physical AD Domain Controller running DHCP.
Vitual AD Secondary Domain Controller

Select the right hardware:

Multi-core CPU's are excellent for VMWare. HT and MultiCore.
1 - Min and max requirements for Wks / Server.
2 - Application Min & Max requirements.

Add 1+2 considering RAM, CPU, Networking, Disk
Divide CPU speed 2 GHz, for example.com:

App1 - CPU 1 Mhz
App2 - CPU 2 Mhz

Dynamic Disk will grow.
Static Disk will not grow. Prefer SATA / SCSI.
Vmware Server do not support SAN/Fibre Channel on virtual machine.

Workaround:

iSCSI / Fibre channel connection over the san put your virtual disk from vmware on that SAN.
You can choose Raid 1,5 or 10.

System 1 - Physical to Virtual env P2V runs "Cake App"
System 2- Implementing Win 2008 with file print and email on it.
System 3 - Linux Web Server
System 4 - DC/DHCP/DNS Server for AD Domain.

CPU - Dual core system of 3.5 Mhz CPU.
Memory - 3GB + 1 GB Host OS = 4 GB should be fine. Add 1 GB for the room for growth.

What should be virtualize:
Print server / Web Server / Networking Monitoring Server

What NOT should be virtualize:
SQL Server with multiple connections.
Financial applications.
Use ESX Server to run mission critical applications.

How do I consolidate servers ? (P2V)

- Reinstall / rebuild.
- Imaging
- P2V conversion Software, vmware converter.
