Selecting an application

Performance on System z CPUs is superior to any other CPUs on any other platforms– CPU speed is not the entire story – it’s in the architecture!– Architecture designed for multiple or consolidated workloads– System z has definite advantage with applications that have mixed

CPU and I/O– System z10 Enterprise Quad Core 4.4 GHZ

System z and z/VM provide the best virtualization capabilities– All workload types are eligible

Good planning is essential IBM can

– Perform sizing estimate– Perform Application Assessment– Perform zRACE TCO Business Case Analysis – Assist with planning and initial installation needs

•Substantial hardware cost savings, especially with System x

•Software is a major cost driver especially WebLogic and Oracle costs per engine. System x provides no relief

•People costs are significantly reduced Productivity would improve with Linux on System z. System z already has IT process and administration tools to run efficiently

Bottom Line: after considerable “what if” analysis, the conclustion for this situation was Solaris is approximately 3-4 times the 3-year cost of zLinux.Planned IT expense of $1.5 million vs $7.4 million…potential savings 79%

IBM S/W IBM Maint IBM H/W

K$

Potential 3 Year Total Cost of Acquisition (TCA) *

Savings driven by:

Consolidation of OTC SW licenses from 22 to 1

Savings increase as solutions scale up to a 54 way System z

Other likely Savings:

Energy – adding 22 Intel servers consume 6358 watts vs. 0 watts for one incremental IFL*

Space – adding 22 Intel servers requires 5 square feet. Turning on an IFL takes 0 and you can have up to 54 of them (or 789** equivalent Intel servers) with no additional space

People – adding an IFL or multiple IFLs will not likely require more people to manage them

Harness the value of a System z9 EC Mainframe’s high utilization and transform your enterprise’s IT costs

First National Bank of Omaha - Ken Kucera, senior vice president and division head of FNBO Enterprise Technology Services

“For every application I had, I needed another one to five servers behind that, for things like development and application and Web serving. And every 20 servers translates to another body to administer them.”

*Microcode upgrade only** Based on 5% composite Utilization

Leverage an incremental IFL in a Web Serving environment and potentially reduce costs by up to 58% when compared to a equivalent Opteron based Sun Solution

•SW stack includes WebSphere Application Server ND, Linux and zVM•Based on estimated capacity measurements, and 5% server composite utilization for Intel, your actual savings may vary

When consolidating Linux on low utilization Intel servers, the System z9 Mainframe’s ability to provide high utilization may

help to reduce both power and facility costs

the System z9 EC

may provide up to

4 times the same

work in the same

space and may

provide up to

12 times the work

for the same

power consumption

The Linux on Intel servers selected in this example are functionally eligible servers considered for consolidation to a System z running at low utilization such that the composite utilization is approximately 5%. The utilization rate assumed for System z10 EC is 90%. This is for illustration only, actual power and space reductions, if any, will vary according to the actual servers selected for consolidation.

Customer Patterns1. Consolidation of simple web-, application-, file-, print-serving

– Customer objective: “try it out” very limited z/OS backend integration very small footprint (1 IFL only), no real mission-critical workload deployed

– All kind of customers types (very small to very large, all sectors)

2. Migration of costly distributed Application Server infrastructure for z/OS DB2-backend processing– Customer objective: “reduce my TCO & get better controls”

tight z/OS integration easy to achieve technical benefits (superior transaction rates & RAS

characteristics) Immediate Systems Managements benefits thru central point of administration Examples: SAP, WAS, WCS, WPS, S2, BEA WebLogic, IBI WebFocus, …

– Primarily FSS and large IND, DIS, COMS customers

3. Infrastructure Simplification– Customer objective: “get back on track in handling distributed environment”

indifferent z/OS integration Customers cannot manage constant growth of distributed infrastructure in terms

of staff, skills, environmentals, controls– Primarily SMB, PUB and small other sector customers

4. Migration of mission-critical end-to-end applications– Customer objective: “run it on the most reliable and most secure platform”

no or very limited z/OS integration Current hosting infrastructure for mission critical distributed Apps too unreliable or

insecure Scope is on Multi-Tier workload (App Servers + DB Server + Front End Servers +

Applications), currently hosted on Unix or Windows platforms Superior RAS, BR & Security characteristics

– Primarily very large FSS, IND, DIS, COMS customers
