SAP HANA comments from past Summits
Maturity of HANA as a DB layer– Improved quality allows porting to POWER
Columnar capabilities– DB2 for IBM i EVIs also provide columnar capability
– IBM i still leads SAP BW-EML benchmark category (500M rows)
Design point - HANA was designed to run OLAP queries– Not OLTP – ie Business Suite
In-memory challenges – SSD and Flash speeds are also orders of magnitude faster than disk
– HANA requires fast disk (for initial load and paging)
– Memory capacity limits are reachable - core/memory ratio

SAP and IBM development perspective
Business as usual – another development interlock this week
We have a growing number of installations to support
We have new OS/DB requirements to fulfill for SAP
SAP is still implementing functions IBM i has already delivered
Customers have not consumed everything we can offer today
Including IBM i 7.3, LaMa, NW 7.50, SAP HA, Flat infocubes…
There is another kernel and NetWeaver release to prepare – In expectation of another Business Suite release in the future
– And another IBM i version and Power9 in development

IBM i and SAP HANA Integration
LPAR support for Linux and IBM i on the same Power box
IBM i Application server for HANA DB
ERP Sidecar – small subset of ERP tables on HANA for queries
Why are so few using this if reporting directly from ERP is so important?

The S/4HANA vision
6
From: SAP Business Suite• One DB per application• Point-to-point integration • Long running queries, e.g.
in batch mode
To: S/4HANA• One DB per landscape• No integration necessary• Real time execution

Definitions - Migration vs Conversion
Migration• Primarily a DB exchange• Most business logic does not need to change• Some risk, some effort and more HW cost • Some things improve, some may get worse as a result of DB change
A Migration does not solve: • Sizing problems – lack of resources• Application server tuning issues• Application or process logic problems
• Ex - Oracle to IBM i, SQL Server to IBM i, SAP ASE to IBM i, etc.

Definitions - Migration vs Conversion
Conversion• Often a DB and/or OS change• Business application logic definitely changes, users notice • New customization required • More risk, more effort and more cost • Some things improve, some may get worse as a result
A Conversion does not solve: • Sizing problems – lack of resources• Application server tuning issues• Application or process logic problems
• Ex - SAP R/2 to SAP R/3, SAP ERP to S/4HANA

Why Migrate Business Suite ERP?
SAP ERP CoreSAP HANA
SAP Business Suiteon HANA
SAP ERP CoreDB2 for IBM i
SAP Business Suite • OLTP is not a HANA strength• Still no SD benchmark
• App server and DB work does not change significantly – it’s still OLTP
• Business Suite growth on AnyDB allowed by new technical foundations• 7.50 NetWeaver OpenSQL• Core Data Services (CDS) • Fiori
• Migration business case is difficult to justify

SAP S/4HANA CoreSAP HANA
SAP S/4 HANA
SAP ERP CoreAnyDB or SAP HANA
SAP Business Suite• S/4HANA is a different application
• Do not underestimate the effort required to convert
• Significantly more change, cost and effort requiredto hope to reach HANA’s potential benefits
• “Simplification”, “Reimagination” = Reimplementation
• Have you customized SAP to your business?• Are you planning to redo all of it? • Or will you change your business process to fit S/4?
• Cloud versions severely restrict customization
• Success must be guaranteed to justify any move
S/4 HANA Conversion?

Migration of Business Suite BW?
SAP BWSAP HANA
SAP Business Suiteon HANA
SAP BWDB2 for IBM i
SAP Business Suite • Remember EVIs and Benchmark successes
• POC experiences have been mixed• Some things improve, some may get worse as
a result of DB change• BW application tuning needs exposed
• Simpler efforts are often more cost efficient• SAP BW EVI button• BW application tuning• DB2 performance health check• SSD/Flash• Flat Infocube

BW Migration & Conversion realities

SAP Business Suite
SAP BW/4 HANA
SAP HANA
• BW4/HANA is another new product line• Like Suite to S/4… BW to BW/4
• S/4 does not accept your existing BW• Infocubes• Reports
• Instead they move to BW/4HANA• S/4 can be a source for BW/4HANA• S/4 does not allow other data sources• S/4 allows only it’s own reports
• Very new – no experiences yet

Adopt SAP HANA 2.0 at “Your Pace”?
SAP HANA 2.0 is just announced in Nov 2016http://go.sap.com/product/technology-platform/hana/features/whats-new.html?url_id=banner-us-homepage-row1-hana2-nov16r1
HANA 1.0 - no new SPS coming
– maintenance revisions until May 2019
HANA 2.0 – “DB Upgrade required after two HANA SPSs are released to remain compliant
with maintenance support”
Regular required HANA updates– Simplifies Support for SAP – but makes work for customers
– Run your business not your computer
SAP on IBM POWER Summit DACH 2016 - © IBM Corporation 2016
HANA DB evolution continues….Independent of application space
Virtualization still evolving for in-memory– Multiple HANA DBs per server
– Performance sensitivity limits in-memory on large machines
– Why so many DBs in the first place?
New HANA DB requirement – “Tenant concept” – additional small HDB instance per LPAR
– Return of MCOD…again, why so many DBs?
HANA HA options still evolving as experience is gained– Options are good to have – proven best practices are better
Code check tools and Data Volume Reduction requirements

SAP NetWeaver 7.50 - bridges Suite-S/4 boundary

New application foundation
Used for both Business Suite & S/4HANA7.50 based tools can check for HANA readiness
SAP wants to use more SQL features that all DBs have now, but not all DBs had in 1990s
7.50 allows many things to work in EITHER world
SAP on IBM POWER Summit DACH 2016 - © IBM Corporation 2016
SAP NetWeaver 7.50 brings options
BW flat infocube (actually 7.40) • Was HANA only, now available on AnyDB
SAP NetWeaver 7.50• Open SQL enhancements
• Available to any customer for own ABAP coding• JOIN, GROUP BY, UNION, string functions, etc
• Core Data Services• DB push-down for HANA and AnyDB• Foundation for “simplification” • ABAP development in Eclipse
• Fiori capabilities• Possible on AnyDB
SAP does restrict some solution availability- Basing on proprietary HANA functions- Customers must have a voice

Leverage your Business Suite investment
Allow CDS infrastructure and S/4 app to stabilizeAvoid temporary products
Business Suite is supported through at least 2025,perhaps longer
POWER9 brings more capacity per square meter in the data center
In the meantime…there’s real work to be done inBusiness Suite with NW 7.50
