Migrating and Consolidating Windows or Unix Workloads to Linux on POWER and OpenPower

Key Factors Driving Linux Implementations

Why accept lower levels of security and reliability when I can provide higher levels of service to my customers?

I don’t want to sacrifice any performance and be sure I am making a strategic decision!!!

Why pay more when you can get the same or better function for less with more flexible licensing?

I don’t want to be locked into any single operating system, platform, or solution technology. It’s about choices.

Mail Server Costs


1) Looking for ways to reduce

licensing costs

2) Desire a more reliable environment

3) Uncomfortable with recent security exposures in Windows

4) Would like to reduce the number of different architectures and operating systems.

5) Have or will create Linux/Unix skills

1) Windows security or licensing costs not a critical factor.

2) Use only Windows-based applications such as Exchange Server and SQL Server.

3) Have invested primarily in Windows skills and has little or no Linux/Unix skills.

4) I am a total Windows shop

Consider Windows if: Consider Linux if:

Should I Move to Linux or Stay on Windows?

…..and when you choose Linux, which platform is best??


Which Platform….Intel based or POWER based?

Decision criteria for Linux server selection:

- Application selection -- is the application enabled for multiple Linux distributions- Application characteristics -- capacity, performance, transaction rates, I/O, floating point, integer - Encumbent system -- do you prefer to run on your existing strategic platform for skills reasons- Reliability -- application availability requirements - Integration -- how do you plan integration, on single system or multiple architectures- Virtualization -- dedicated system or virtual servers - Device Requirements -- are all devices supported as needed- TCO -- does solution offer favorable total cost of ownership


Platform Characteristics^ xSeries ^ pSeries

IBMserver

pSeries

•Primarily 32-bit•Evolving 64-bit•Windows or Linux•Real memory to 32GB •Scalability to 16 way•Growth by scale-out•Virtualization via software

•64-bit proven architecture•Ability to run 32-bit or 64-bit applications•AIX or Linux•Supports scale-up and scale-out•Large memory capabilities – to 1 TB•High scaling – to 32 way•Hardware virtualization engine•Defined future growth path•Very high reliability characteristics•Very high performance capabilities•Surprisingly low TCO


Linux on POWER – the best choice

Linux on p650 provides the lowest TCO-290% less cost than Sun

-60% less than IA-32 Windows cluster & 13% less than IA32 Cluster with Linux

-30% less than clustered Itanium2 systems and 3% less than single Itanium2 SMP PLUS the highest Quality of Service

-Uniques On-Demand features for dynamic growing enterprises

-Expandability for p650 much greater than Itanium – POWER family, memory, disk, etc

-Significantly higher reliability than Intel – cost of downtime not included

-Hypervisor for p650 superiority to VMWare or clusters – more efficient

-p650 also delivers the lowest $ per operations/sec by over 10%

-TCO advantages only get better with POWER5 and other future products

good chart to show RAS differences...could use it afte the linux distributor chart to show Linux on POWER has advantages over Linux on Intel in the RAS area.

•Key application areas that apply to Windows Migration to POWER:


Migration Approaches to Linux on pSeries:

If you already have IBM pSeries installed, you can utilize the partitioning capability of the servers to consolidate your workloads onto these servers using Linux.

• Simplify the IT infrastructure and reduce cost.

If you are running mission critical applications on NT or Windows, you should consider running these applications on Linux on POWER based servers (IBM pSeries or BladeCenter JS20) so you can enjoy the RAS of the enterprise platform in a lower price.

• Simplify the IT infrastructure and increase the reliability


Migration Decisions

For server consolidation opportunities, consider a scale up or scale out solution with JS20 or pSeries models with virtualization engine. This will allow you to run AIX and Linux workloads side by side.

Consider a pilot on a segment of your infrastructure to get comfortable with migrating Linux. Consider using the OpenPower 720 box as a low cost entry point

Infrastructure, such as File and Print is typically the best first step for Linux.

Leverage the IGS Linux Application Center – Linux application porting

Consider utilizing the IGS Linux Migration Practice
