HCL:- Hardware Compalibity List
·
CPU should- Intel- VT-X and AMD- AMDV
·
Intel should VT-X + EPT technology. Without this 64 bit Machine will not power on
But 32 bit machine will be
power on
·
AMD- should AMDV + RVI technology. Without this 64 bit Machine will not power on
But 32 bit machine will be
power on.
·
For 64 bit machine require:
Intel- VT-X + EPT
AMD- AMDV + RVI

Why is Hardware
Compatibility so important?
· ESX runs directly on your hardware
· ESX talks directly to your devices like the video card,
SATA/SCSI controller, and NIC
· ESX is your operating system
· ESX may run poorly or, more often, just won’t work
·
New
name-brand servers will work
·
can
even run ESX inside Workstation to test
The Commercial Versions
of ESXi are:
· Has a direct console instead of a full console (when
compared to ESX)
· Potentially better than using ESX
· Take up fewer resources on that host
· Require less patching than ESX
· Potentially. More secure
· Allow for all the advanced vSphere features
· Install and Boot faster
· Highly recommended
The Difference between
ESXi free, ESXi Installable, and ESXi Embedded
·
ESXi
is available in 3 versions
·
Free - unlimited use
but has limitations
·
Installable
- commercial version of ESXi that you download and install on your own server -
fully
·
supports all
advanced vSphere features that you have licensed
·
Embedded
- ESX image preinstalled as firmware in the factory or burned onto an external USB
key
Installation Tips and
Tricks
·
ESXi
image and installer is called the “VMvisor”
·
Make
sure VT is enabled in server BIOS
·
May
need to press ESC or change boot order to boot installation CD
·
Even
on a slow computer, installs and is ready to use in 5-10 min.
·
Always
installs in 60 day evaluation mode
Five steps to
configuring your new ESXi Server
1.
Set
root password
2.
Configure
IP address, SM, DG, DNS servers, hostname, and domain
3.
Add
to your DNS server
4. Add to vCenter by DNS name
5.
Optionally-
configure lockdown mode and connect to SAN
What is vCenter
Server
Centralized control and
visibility for multiple ESX/ESXi hosts
Contains centralized
license
Necessary for most
advanced features of vSphere
Advantage of
vCenter
Scalability- Expansion
Automation- Automate features
Visibility- Visible
vCenter Server Software Requirements:
·
Windows 2003 Std. Ent. Or Datacentre 64 bit Sp2
·
Windows 2003 R2 Std. Ent. Or Database 64 bit Sp1
·
Windows 2008 Std. Ent. Or Database 64 bit Sp2
·
Windows 2008 R2 Std. Ent. Or Database 64 bit Sp1
·
Microsoft .Net 3.5 Sp1 framework
·
Microsoft Windows installer 4.5( if using SQL 2008 R2 express)
vCenter Server Database
Requirement:
·
IBM DB2 9.5& 9.7
·
Ms Sql Server 2008 R2 Express
·
Ms Sql Server 2005
·
Ms Sql Server 2008 & 2008 R2
·
Oracle 109 & 119
If vCenter Server failed
HA – Will Run
DRS will not run
FT- Will run
Vmotion- Will not run
Svmotion will not run-
Distributed switch – will run because distributed
switch creates & manage at datacenter level
but after copy of distributed switch creates on ESXi
host.
·
Every VM centre server has its own Database
·
Every VMcentre server has unique Database
Installation Requirements
and Prerequisites
Ø 2 CPU 2Ghz Intel or AMD x86
Ø 3GB RAM
Ø 2GB free on disk
Ø SQL or Oracle DB -OR- you can install SQL Express during
the install (may require more
Ø resources)
Ø 1Gb NIC
Installation
Requirements and Prerequisites
· Windows XP Pro SP2 (SP2 required)
· Windows Server 2003, SP1 and SP2 32bit and 64bit all
editions
· Windows Server 2003, R2 and SP2 32bit and 64bit all
editions
· Windows Server 2008 32bit all editions
· Windows Server 2008 64bit Standard and Enterprise
editions
· You can install vCenter in an ESX VM
· For physical server install, you must have a physical
DVD of vCenter
· Do not reinstall vCenter if you really want to do an
upgrade
·
Ensure
that your vCenter server is a member of the domain and you are logged in as administrator
· Correct time and date (recommend NTP)
Installation Requirements and Prerequisites
• Computer name cannot be more than 15 characters
• vCenter server should not be AD DC
• Account you are installing under should have-
Member of administrator group Act as part of Operating System Log on as a service
Installation
Requirements and Prerequisites
· Must have a static IP address
·
Server
must be in DNS with matching name and you must be able to resolve it from all ESX
hosts
· NTFS formatted disk
· Know if you will use standalone or linked mode
· You can run the installers from a network drive but not
install it on a network drive
Installation Requirements and
Prerequisites
·
Database
is required for vCenter and Update Manager
·
Database
Options-
· Install on an existing SQL Server or Oracle DB -Install
SQL Express on the local vCenter
Server
·
For larger
deployments, a separate DB is recommended for vCenter and Update Manager
·
Each
vCenter server must have its own DB
·
For an existing DB,
check to ensure that your version is supported and that it has the necessary
patches installed
·
For existing DB, you
will need to create a 32-bit DSN prior to vCenter server installation
·
If
you use SQL Express local option, standard DB maintenance must be performed

New Licensing Changes in
vSphere
· License keys are 25 characters instead of complex files
· No more license server - built into vCenter
· Only License keys for each edition of vSphere - no
feature keys
·
License
keys has encoded CPU Qty
Advantage to installing vCenter in a VM
·
No
Physical machine required
·
Can
use vMotion to move it from one ESX host to another for maintenance
·
High
Availability is provided if you put it in a VMHA cluster
·
Can
use snapshots before upgrades, etc.
·
Can
back it up with same method as other VMs.
·
ESX
hosts are not 100% dependant on vCenter
