Agenda
Server Selection
The initial cost problem
All cores are not created equal
Oracle DB example– Why are non-virtualised servers under utilised?– Virtualisation support– Software costs– Adding redundant server
WAS example– Virtualisation built in or added on?– With or without limits?– Benefits of a big pool– Effect of workload spread– Software costs– Adding redundant server– Scaling up to larger customer levels
Combined Oracle and WAS example

OLTP Performance results for Servers under consideration
The IBM Power Systems servers outperform the HP servers, particularly when looked at core by core.
All cores are not created equal. IBM Power Systems can run more threads faster, which means workloads run faster and less cores are needed, which lowers costs

Oracle Certification For VMware and KVM
Running Oracle in a VMware ESX cluster you must license ALL of the cores in the cluster
Oracle DOES NOT recognise VMware as "hard partitioning"
http://blogs.gartner.com/chris-wolf/2010/11/10/oracle-broadens-x86-virtualisation-support-but-work-remains/
Running Oracle in a VMware ESX cluster is not certified. If support is required for unknown problems then you must recreate the problem without VMware installed view Oracle Metalink document 249212.1
Red Hat Enterprise Linux 5 integrates Kernel-based Virtual Machine (KVM) and ships Xen as the default hypervisor, so they are supported by Oracle under the Oracle Linux support program. However, Oracle does not support Oracle products on RHEL's KVM/Xen.

Effects of Utilisation - Graph View
With utilisation effects added, the hardware costs become more comparable, and facilities requirements are much lower with the IBM Power 770.
With IBM Power, virtualisation is built into the hardware and always on. This enables any workload to be virtualised, allowing high utilisation of resources. Less resources are therefore needed, reducing costs.

Java Performance results for Servers under consideration
The IBM Power Systems servers outperform the HP servers, which continues across to the smaller IBM servers when compared to the smaller HP servers
All cores are not created equal. IBM Power Systems can run more threads faster, which means workloads run faster and less cores are needed, which lowers costs

Adding Virtualisation to Benchmark Results - Graph View
Rolling back to the performance results, and adding the 20% overhead for VMware has the IBM Power Systems as still the most expensive to purchase, but the facilities requirements become more competitive.
With IBM Power Systems, virtualisation is built into the hardware, adds no overhead and is always on. Less resources are therefore needed, reducing costs.

Resource utilisation through virtualisation
Individual workloads tend to peak at different times, and need higher quantities of compute resources only when they are running at peak
At other times, resources may not be required to the same degree
Virtualisation can enable the use of these spare resources, driving higher utilisation of the physical resources
The larger the number of different workloads operating on the same physical server, the greater the benefit from resource sharing that can be observed
From detailed modelling of customer workloads, it has been observed that spreading workloads across additional physical servers can reduce the benefit from virtualisation
– The total requirement for compute resource in this model increased by 15% with each additional server
Significant over allocation of resources is also possible through virtualisation– The sum of the peaks from each individual workload can commonly be 2 or 3 times the maximum
peak on the virtualised server. Higher rates of over allocation are possible.– As CPU resources are used more effectively, additional memory can be needed– IBM Power Systems can accommodate more memory, and can use features such as Active
Memory Sharing and Expansion to optimise the use of the installed resources.

Adding effect from multiple servers - Graph View
Working in the effect of spreading the workloads over multiple servers shows the IBM Power 770 is competitive in the facilities requirements, but the IBM Power Systems still have higher purchase list price costs.
IBM Power allows larger pools of virtualised resources. Spikes in workloads can be accommodated with fewer resources. Less resources are therefore needed, reducing costs.

Combined WAS and Oracle RAC at large customer scale - Graph ViewIf IBM Power 770s are used for combined WAS and Oracle DB, particularly at the scale of a larger customer, they can have the best 3 year TCO. Also, the best facilities requirements are with the IBM Power 770s.
At the scale larger customers operate at, both the software costs and the facilities requirements can be considerable. IBM Power servers can lower both, allowing high levels of expense to be avoided.

Summary
All cores are not created equal– IBM Power can run more threads faster, which means workloads run faster and less cores are needed, which lowers costs
With IBM Power, virtualisation is built into the hardware, adds no overhead and is always on.– Less resources are therefore needed, reducing costs.
IBM Power allows larger pools of virtualised resources.– Spikes in workloads can be accommodated with fewer resources. Less resources are therefore needed, reducing costs.
With the above factors being considered, the hardware costs for IBM Power can be comparable with the equivalent total HP hardware costs
At the scale larger customers operates at, both the software costs and the facilities requirements can be considerable– IBM Power servers can lower both, allowing high levels of expense to be avoided.
Some Enterprise level software has costs which are much higher than the hardware.– IBM Power can require far fewer processor cores, lowering these costs, resulting in a much lower cost of the solution
Other software has lower costs, but IBM Power can still be competitive– Fewer servers are needed, reducing administration and facilities costs
IBM Power and AIX then have a number of features that add value above Linux on x86– More secure, less patching needed, can virtualise any workload, LPM, RAS, Active Memory Sharing and Expansion,
WPARs, etc
Taking in all these elements, IBM Power Systems offer solutions that can save money over x86 based solutions, and deliver higher levels of business value.

Conclusions and possible next steps
Hopefully my modelling and ideas have given some food for thought
But how the customer models costs and assigns value is far more important
Can we work with you on your models, working some of these ideas in, so IBM Power systems can compete effectively for workloads?
Thank you!

Some questions to consider
What are you planning to run?
What is the reliability needed?
How flexible does it need to be?
Do you have peaks during the year, month, and/or week and how do you handle them?
How secure does it need to be?
How complicated it is to install and run?
What skills your staff already have?
What would be your evaluation criteria?
Which of these business needs would have more weight?
Do you have a total budget assigned for this project?
