4. HOST SERVER HARDWARE SELECTION
• What to look at when selecting server hardware for a Host
- CPU Speed - More RAM the - Use SAS not SATA - More NIC ports
- No of Cores better - Higher RPM the better
- x64 bit - NUMA – check Speeds better - 1Gb/10Gb
- Supports RAM module - Local/Shared - VLAN support
Hardware install sequence Storage - TOE/VMQ
assisted - Dynamic Memory - SSD are faster - Storage access
Virtualisation in SP1 and are more - FC HBAs
(AMD-V/Intel-VT) reliable - 10Gb NICs
Slide 4

5. HOST SERVER HARDWARE SELECTION
• Should I create my private cloud on Blade or Rack servers?
Blade Servers • Smaller physical footprint
• Highly reliant on Blade enclosure – backplane
could be single point of failure, high
availability also requires two enclosures
• Server has limited expansion/upgrade options
• High density means more heat generated in a
single area – cooling considerations
Depends what fits your requirements better!
• Supports a higher density of Network and
Rack Servers Fibre ports
• Greater number of RAM slots available
• Greater number of local disk options
• Can be easily moved to another site or rack
• Power consumed maybe slightly more than
Blade servers
Slide 5

6. STORAGE HARDWARE SELECTION
• Shared storage is critical in supporting a Highly Available
virtual infrastructure.
• What features do I look for in storage
• Support for FC or iSCSI or both [FC – 2/4/8Gbps and iSCSI 1/10Gb]
• De-duplication File system and LUNs stored in
• Fast cloning Dynamic Flexible Volumes

• Data Replication to support DR 100

• Storage sizing – Plan for current GB
and future requirements
Flexible Volumes
(2TB Provisioned)
• Most important remove all single
points of failure – Multiple RAID Groups
paths to the storage should
Aggregate Physical Storage
be implemented in production. (1TB Total)
Slide 6

7. STORAGE HARDWARE SELECTION
• So many storage vendors out there - how do you choose?
• Firstly leverage off your existing storage vendor
• Analysis of two storage vendors solutions we have
deployed in the past
NetApp FAS SANs HP Lefthand SANs
• Supports FC and iSCSI out of the box • iSCSI based SAN only
• RAID-DP disk protection • Unique feature - Network RAID
• Thin Provisioning, Deduplication, Fast • Virtual SAN Appliance available
Clone • Start small, grow seamlessly
• Data Replication and Snapshots

8. TIPS & TRICKS: HOST SETUP
Full or Core Installation Installing Antivirus on the host – exclude
Host selected files and folders
Storage connections Network connections
• Fibre Channel – ensure multi-path enabled. • More NICs the better when
• iSCSI – Windows does not support NIC configuring hosts – ensure
bonding for iSCSI, hence use separate NICs correct binding order
with multi-path enabled. • Enable new network
features – Jumbo Frames,
VMQ
Biggest Tip for 2011: Install Windows 2008 R2 SP1 to get
access to features like Dynamic Memory and Remote FX.

9. TIPS & TRICKS: WORKLOAD
MIGRATION
• Your environment is probably running many different types of OS
OS Type Notes
Windows NT Will run on Hyper-V – not
supported by MS
Windows 2000 – 1 vCPU only, Was officially supported until
max 4 disks 13th July 2010
Windows 2003 / 2003 R2 – up
to 2 vCPUs
Windows 2008 / 2008 R2 – up R2 no need to install
to 4 vCPUs integration components
Linux Distributions – now up Official support for SUSE 10 +
to 4 vCPUs and RHL 5.2 +
• Check with software vendor on supportability
• Check resource requirements for the workload – MAPS Tool
• Migrate Test/Dev servers first
• P2V or New – depends but Domain Controllers always new
Slide 9

10. TIPS & TRICKS: COM AND USB PORT
ATTACHED DEVICES
• Do you think that all workloads can be virtualised?
• What about devices attached to the…
MOXA NPort 6150
COM Port
www.moxa.com
USB Port SEH myUTN-80
SEH myUTN-50 www.seh.de
SOLUTION: Make the devices IP enabled over the network.

11. CUSTOMER SCENARIO: BASIC
VIRTUALISATION
VM VM VM VM VM VM
• Start with 2 hosts and connect them to shared storage
• Install Windows 2008 R2 OS [Full Installation]
• Enable the Hyper-V Role
• Enable the Failover Clustering Feature and create a
Hyper-V cluster
• Migrate workloads – P2V or Build New VMs
• Need min two for failover cluster
Why start with 2 hosts? • Though need to reserve 50% of the RAM on each host
What happened when we add • Adding another host enables more workloads to be hosted.
another host? • 3 hosts the RAM needed to be reserved is 33% on each host

13. CUSTOMER SCENARIO: VIRTUALISATION
ON BLADE SERVERS
+
• Customer has purchased a number of blade servers and a single blade
enclosure
• Server specification is 4 sockets - 6 core, 128GB RAM, Local disk for OS
and NetApp attached shared storage, 4 NICs.
• Customer had configured 4 VMs with 30GB RAM each on each host
• VMs and VHDs were stored on a single LUN from NetApp attached
exclusively to one host.
• Patching requirements reduced – power, network, fibre channel
• Reconfigured NetApp storage to support a Hyper-V cluster
• Reconfigured and reinstalled hosts and created single Hyper-V cluster
• Features such as live migration and high availability enabled by cluster
• New project requirements now raise the consolidation ratio to 10:1
• Windows 2008 R2 Datacenter edition and Server Management Suite –
Datacenter purchased
• SC Virtual Machine Manager and SC Operation Manager deployed

14. CUSTOMER SCENARIO: MS EXCHANGE
VIRTUALISED
VM VM
DAG
• Virtualising Exchange – Supported on Hyper-V?
Exchange 2003 Exchange 2007 Exchange 2010
• Check out Microsoft Support Policies
• Exchange 2003/2007 - http://technet.microsoft.com/en-us/library/cc794548(EXCHG.80).aspx
• Exchange 2010 - http://technet.microsoft.com/en-us/library/aa996719.aspx
• “Microsoft doesn't support combining Exchange high availability
solutions (DAGs) with hypervisor-based clustering, high
availability, or migration solutions …”
• How to implement on Hyper-V?
• Exchange standalone - OK to go on Hyper-V cluster
• Exchange HA solution (DAG) – Need to go on standalone Hyper-V hosts
