When to Migrate from UNIX to Linux


When to MoveDo You Suffer from Any or All of These?

Aging hardware with poor price/performance

Older applications need upgrading

High hardware/software maintenance and support costs

Increasing operational costs (power, cooling, real estate)

Pressure to internationalize and adopt UNICODE

Vendor lock-in

Data center space is constrained

The Linux Value Proposition


Linux has become the reference platform for enterprise databases

Linux is reliable, scalable, secure and high performing

x64 hardware costs much less than RISC, SPARC or POWER, while providing excellent performance

Linux deployments provide IT with more choices and greater flexibility

Why Move from UNIX to Linux?


2007 server expenditures: US$8.6 billion 2009 server expenditures: US$10.5 billion

Third Generation Linux


The customer profiles and migration drivers have evolved as technology scales and Linux matures

– Stage 1: Early Adopters> Driven by cost-efficiency and stability while keeping System

Administration overhead under control> Industry sectors without critical performance or availability

requirements

– Stage 2: First wave of wider adoption> Driven by cost, with critical performance and availability

requirements taken for granted> Wider industry sectors

Customer Profiles andMigration Drivers


Customer Profile and Migration Drivers

COMMON TREND: COST EFFICIENCY

– Stage 3: Widespread adoption (Current stage)> Driven by availability of powerful, commodity hardware as

well as the high degree of automation that Linux provides> Industry sectors widespread and include areas such as

Utilities and hosting companies> SAP on Linux installations today operate with high capacity

and availability requirements


Lower Your Costs

Hardware PurchaseUNIX loads typically run on Linux using industry standard servers that cost up to 75% LESS than comparable RISC systems for UNIX

Hardware MaintenanceThe move to commodity hardware drives a reduction in annual hardware maintenance costs of up to 90%

Software License CostsCommercial Linux subscription fees are typically up to 60% LESS than the license costs for the UNIX systems they replace


What's the Truth about Costs?

Cost has been a primary motivator for SAP migrations to Linux. But vendor comparisons between software and hardware platforms are often biased.

How can you find the truth?

REALTECH has built a framework to normalize CPU power and hardware costs for cross-

platform comparisons.


Key Findings: Linux versus UNIX

• x64 architecture provides the greatest cost advantage – while providing high levels of performance

– High-end computing and memory capacities at commodity equipment pricing

– Multi-core and multi-threading technologies have multiplied CPU power to a great extent

– Modern 2 or 4 processor commodity servers outperform much larger, yet older (1 or 2 yrs.) systems

> First x64 architectures ranged around 1,000 SAPS per CPU in 2005> Current x64 architectures range between 4,500 to 6,100 SAPS

today

– Capacity 'overkill' with commodity hardware is a common occurrence today

x64x64

Observations:•Top 4 systems are x64 based •Some of the top 4 systems perform faster than some of the higher-end processor architectures – providing cost and performance advantages•Commodity 4- and 8-way x64 systems now reach performance levels previously achieved only by 8-way (or higher) systems running UNIX•Competition between Intel and AMD keeps x64 architecture constantly updated and costs very competitive

Yellow = Dual-Core, Green = Quad-Core, Blue = Eight-Core


• Indirect cost savings drive the migration to Linux from UNIX from an operating system standpoint

– UNIX technical staff are more easily trained on Linux (have greater affinity for Linux)

– No major programming issues when migrating scripts, programmatic interfaces or transport files, and no major disk drive adoption issues

• These issues, while small, frequently add up to make a decisive difference in favor of Linux

Key Findings: Linux versus UNIX

If Linux is your choice, you can confidently move to this open-source platform in the knowledge that SAP solutions running on Linux are as robust and enjoy the same full support and long-term commitment from SAP and its global partners as they do on every other operating system.

Similarity to Traditional UNIX Leverages Existing Skills

Linux has an extremely high affinity to commercial UNIX: therefore migration effort and organizational impact are smaller than switching to windows

• Nearly identical OS philosophy:– Little differences in existing OS scripts– Unchanged volume management– Similar or identical backup/restore and HA procedures– No adaption of existing paths– No EOL/EOF problem with co-files in the transport directory

• High transfer of know-how from UNIX to Linux– UNIX admin teams often already know Linux, or easily acquire Linux

knowledge– High acceptance for Linux among UNIX admin teams


Independence

• Best Practices from top consultants

• No dependencies to any hard- or software vendor

• Facts only

• Reliable and sustainable

Experience Know-How

• More than 600 successful migrations

• Preferred partner for SAPmigrations for both Microsoftand Novell

• Projects on global and local scale

• Planning and implementation of migration projects for several years

• Infrastructure analysis, proofof concepts and feasibilitystudies for hardware vendors and end customers

• Certified migration specialists only!

• Great connections to SAP

• International knowledge transfer

• The only independent consulting company in the SAP LinuxLab

SAP ERP Infrastructure Two Years Later


• Server Upgrade necessary due to ever more frequent performance bottlenecks on CI/DB side

– Additional application servers don‘t help

– Existing UNIX-Servers obsolete

– Existing XP256 disc storage system obsolete and mainframe oriented (insufficient I/O)

• Pending introduction of new NetWeaver/ERP components:– SCM: eProcurement

– SEM and BI: Enterprise Planning

– CRM: Extension of functionalities

• Extended Requirements on Business Continuity (7 x 24)• Renewal of infrastructure and CI/DB server HW unavoidable

Very Typical UNIX-to-Linux Aspects of This Case• The UNIX to Linux migration contributes to significant cost

savings

• There is plenty of UNIX know-how and also production experience with Linux application servers for SAP

• Linux is highly accepted and welcome in the existing SAP team

• The existing UNIX infrastructure is close to end of depreciation

• The existing UNIX infrastructure needs to be extended or replaced due to performance aspects and new business requirements

• The customer needed a migration partner ensuring success, which was triggered by the question “Is Linux ready for our mission-critical applications?”
