5. Implementing Virtualisation
 Brief introduction to Online Support.
 Background to Virtualisation.
 How can Virtualisation benefit your business?
 Tips on implementing Virtualisation solutions
that don’t cost the earth.
www.onlinesupport.co.uk

6. Who Are We?
 IT Solutions and Managed Services company.
 Based in West London.
 Established in 2002.
 Since then we have developed an expertise in
Virtualisation solutions.
www.onlinesupport.co.uk

7. Did You Know?
 “Enterprises that do not leverage
Virtualisation technologies will spend 25%
more annually for
hardware, software, labour and space for
servers”. (Gartner)
 “The average Virtualisation rate is moving
from 20-40% today to 60-80% by 2015”.
(Gartner)
 85-90% of the machine’s power is unused.

9. Benefits Of Virtualisation
 Efficiency and cost reduction
- Reduce hardware cost.
- Reduce power consumption and cooling.
 Flexibility
- Easy to increase resources to a virtual server if and
when required.
 Improves Application Reliability
- Becomes cost effective to have multiple
servers, each dedicated to a specific application
(reduces risk of conflict between applications).
 Simplifies Server Replacement and Disaster
Recovery
- Virtual servers are hardware independent.

13. What Does A Storage Device Consist Of?
Array of Hard Drives
 Array of hard drives to store your virtual servers’ images.
 These drives should be in some form of RAID array for
redundancy.
www.onlinesupport.co.uk

14. What Does A Storage Device Consist Of?
Storage Processor

 Storage processor to act as an interface between the
physical computers and the hard drives.

 Each Storage Processor is connected to an iSCSI switch.
 These in turn are connected to both Physical Computers.
 This provides a highly redundant set up with no single point
of failure.

19. DAS Or SAN Storage Device ?

Storage Processor
 Look at using a form of storage device called a DAS (Direct
Attached Storage) device - much cheaper than SANs.
 Directly attaches to the physical computers so removes the
requirement to purchase iSCSI switches .
 Can still be supplied with dual storage processors which can
be connected to up to 4 physical computers in high
availability mode (some models only).

24. Demonstration
Microsoft Hyper-V in High Availability
www.onlinesupport.co.uk

25. What Will The Demo Cover?
 How traditional hardware resources are provisioned in a virtual
environment:
- Processor
- Hard Disk
- Memory
 Failover clustering
- What does shared storage and multi-node mean?
- Demo a machine failing over from one node to another.
 Before we start, let’s use an analogy to get your head around
Virtualisation.
www.onlinesupport.co.uk

26. Demonstration Summary
 Virtualisation is moving from being bound by the physical
constraints of the hardware to having access to a much larger pool
of resources across 1 or multiple hosts in a cluster.
 Your servers become images on a hard drive instead of physical
pieces of tin; so they are infinitely easier to manage, transport,
upgrade and restore.
 Even if you only have 1 server it is worth virtualising it when you
upgrade, for the following reasons:
– MS HV is free – it doesn’t cost you any more to virtualise compared to
replacing the tin.
– You are future proofing your infrastructure by making it far more
flexible to accommodate future demands e.g. adding an additional
server.
