Why would you want to do that?


Best boxes for
vSphere


Where to get them


Datacentre

in a box (virtualized ESX)


Muti

Node TARDIS cluster Demo


Performance I/O Demo


FT Demo


Cheap/Free SAN Storage


Cheap/Free Networking


Software Licensing


Further Information...



Because you can



VCP study


Critical home infrastructure (wife & kids 2.0)


IT is a vocation, not an occupation


Production use cases


Automated install testing


Changes (ITIL)


VUM patch testing



Need:


Cheap

Power!!!


Quiet


Options


eBay an old Proliant


Buy something cheap but less “server”


Find someone else to pay for it (good luck)


New HP ML115 G5 / ML110 G5


With 160Gb HDD, 8GB RAM, dual/quad core ~£330


ML115 G5 is weapon of choice (AMD x64, FT)


Used HP D530


160Gb HDD, With 4Gb ~£90


ESX 3.5 only (not x64)

That “spares” pile


but ask 1
st
!





2 x Physical HP ML115 G5 with
8Gb RAM vSphere 4 Servers


1 x HP D530 OpenFiler (1TB
iSCSI storage, 60Gb SSD)


Cheap VLAN’able GbE switch


10 x virtual ESXi instances in a
HA/DRS cluster


4Gb RAM allocated to each
instance (heavy overcommit!)


Software L3 router; Vyatta


Trolley & luggage straps (B&Q)


Approx cost to buy <£1,000


Non

HA version ~£500


Even cheaper if you can recycle
the OpenFiler box & Storage

These are really
vNICs

Note: no need to specify
VLAN tag


it is done on
host


It’s bigger on the inside than outside


vMotion between physical host & VM ESXi
(Nested VM)


Host Profiles


VMware Update Manager


Nested Virtual Machines (configuration)


FT (FT’d vCenter & Vyatta installation)







Separate VLAN’s for storage,
vMotion
, FT


VM Template with multiple
vNICs

& mounted
.ISO


Do not clone installed
ESXi
/Classic


Physical Host


set
vSwitch

to allow promiscuous
mode otherwise it will not work


Pay attention to max number of ESX hosts to a
single shared LUN (or it will stop working)


Nested VM with FT needs special VM
configuration & doesn’t work brilliantly


Virtual ESX servers need
monitor_control.restrict_backdoor

TRUE setting
to run nested VMs



SATA, consumer grade SSD is cost
-
effective


Don’t expect amazing performance, but good
-
enough


Beware of iSCSI reservation conflicts


OpenFiler


Free, open
-
source, wide hardware support


Will also run as a VM (caution with HA testing)


Replication
possible

if you are a Linux
wizz


HP
Lefthand

Virtual Storage Appliance


Not free

EMC
Celerra

Virtual Machine


Resource hungry


Free


Fully featured


(..more coming from EMC soon;
CLARiiON

etc.)


NAS


Drobo
/IX
StorCentre



There are no cheap L3
switches


Old L3 Cisco kit is <£100 but
not Gigabit (eBay)


Solution


Cheap SoHo GbE switch that
supports VLAN’ing


Linksys SLM series ~£80 for 8
GbE ports & VLAN support


Vyatta software appliance router
(VM with multiple vNICs


Configure router VM with FT



VMware software is an expensive problem for the lab

using production keys; naughty


The Internet; naughty


No real product activation at present or viable solution to this
problem from VMware


No more VMTN subscription!


Microsoft


Mainly for guest VMs or you could try out Hyper

V or
Xen

if you
can’t get an
eval

license from VMware to use in your lab



Downloadable
evals


TechNet Direct


best approach to be legal, and reasonably priced
with lots of copies ~£300 unless you go to
TechEd

then it’s free

Nothing to see here, move along


it’s free!
