Traditional x86 Architecture
• Single OS image per machine
• Software and hardware tightly coupled
• Multiple applications often conflict
• Underutilized resources
Old Standard Server Approach
Copyright NorthgateArinso. All rights reserved.
Previous Application Landscape
Data Base
Data Base
Data Base
In traditional application deployments, there can be significant server sprawl primarily due to the need to provision separate systems for:
• development (DEV),
• quality assurance/test (QAS)
• production (PRD) environments.
Data Base
Data Base
• What about hundreds of customers
(and systems) ?
• Complexity of large implementation ?

Virtualized (Shared) Architecture
• Virtualization ESX Server
• Runs directly on hardware
• Advanced Resource Management (cpu, memory, disk, network)
• High performance and high throughput
• SMP Capability
• Clustering across physical servers
• Multi-OS supported
Actual Virtualization Approach (1/2)
Copyright NorthgateArinso. All rights reserved.
• Reduce costs by consolidating services onto the fewest number of
physical machines as Infrastructure needs
•Maintenance, Leases
•Networking
•Floor space, Cooling, Power
•Disaster Recovery
• Provide failover and high availability
• Isolate environment but shared hardware
• Make better use of capacity
• Remove/reduce the limited flexibility in shared environments
• Provide more opportunity for server maintenance during normal working hours
• Allow heterogeneous environments (OS) on the same hardware
Actual Virtualization Approach (2/2)

Virtualization Features
• DRS Business-customer Impact ?
• HA Business-customer Impact ?
• VMOTION Business-customer Impact ?
• Align IT resources with business priorities,
• Operational simplicity; dramatically increase system administrator productivity,
• Add hardware dynamically to avoid over-provisioning to peak load
• Cost effective high availability for all applications,
• No need for dedicated stand-by hardware,
• None of the cost and complexity of clustering
• Zero downtime,
• Complete transaction integrity,
• Continuous service availability,
Hardware maintenance without scheduling

Virtualization
Additional Business Advantages …
• Rapid Provisioning & Change Management
• Each new major Application release requires 20-25% more resources
• Move old systems to new hardware easily
• Free-up space from old hardware,
• Benefit from compute power immediately
• Simple maintenance of old application system for compliance
• Realize immediate ROI
• Decrease data centre costs: hardware, labor, floor space, energy,
cooling
• Easier to manage less resource
• Agility & Adaptive
• Can align/adjust/adapt faster „business/application‟ to the market
changes/business requirements.
Copyright NorthgateArinso. All rights reserved.
Virtualization New Challenges …
• Security
• The virtual layer will become a potential target for attack for the virtual
services (multiple virtual machine) being hosted.
• Network access (dedicated NIC, VLAN, …)
• Management
• Costs estimation, ROI, …
• Additional tools
• Storage
• To be optimum, a SAN/NAS is “required”.
• VMWARE features (Vmotion, HA, DRS…)
• Backup/restore/DR
• Space efficiency
Virtualization Some Figures
• 20 ESX servers in DCA, 20 ESX servers in DCB
• ESX servers used for ERP (customers)
• ESX servers used for DMZ
• Total Virtual Machines : +/- 450
• ERP DCA = xx
• DMZ DCA = xx
• ERP DCB = xx
• DMZ DCB = xx

Storage Features: Management Software 4 Years ago ...
• Test all SnapManagers during POC
• Nice tools if you want a graphical interface
• Works fine to make a Snapshot
• Poor integration with SnapMirror
• NO integration with SnapVault
• Created custom scripts for Oracle and SAP
• Created custom scripts for Vmware based on VIBE script, SnapCreator
• Now testing Snapmanagers again
Storage Features: Protocol NFS ???
Strengths Delivers best IO scaling for
shared datastores
Simplest storage management
Transparent storage virtualization
Inexpensive storage networking
Eliminates storage dead spots
No restriction with vSphere feature set
Be Aware: Not as common outside of NetApp & EMC installs
Our largest customers have adopted NFS for simplicity and scalability
