SAP HANA is strategic for SAP
Since 2011 available with SAP Business Warehouse
Since 2013 with SAP Business Suite (“Suite on SAP HANA“)
Base of the „Simple…“ roadmap / S/4 HANA
that redesigns central modules
Future SAP solutions will probably
only be available with SAP HANA

Reflections
SAP HANA is strategic component from SAP
Virtualization on IBM Power Systems
has proved to work very well for HR-Group
Suitable point of time in the
HR-Group hardware life cycle
Ramp-Up Program started by SAP
High interest from IBM and Hardware partner FUM
Great opportunity and timing to migrate
to SAP HANA on IBM Power Systems
We wanted to change as little as possible on NetWeaver
HR-Group

Architectural Concept for the SAP InfrastructureAbstract:
This architecture assumes that the existing workload is distributed over three identical Power8 S824
systems. If in the future more compute power and memory is required, this can be done via PowerVM and
AIX license increase of the available CoD resources.
Characteristics:
Distribution of LPAR’s on three symmetrically equipped Power 824 systems across the two data center
(load-balancing and high availability)
On each physical server will be 2 VIOS server installed for redundancy
All DB and application server instances are mapped to these systems in micro-partitions and "fully
virtualized". Virtualization refers to all components: CPU, memory and I/O adapters
I/O adapters are hot pluggable
The integrated virtualization PowerVM Enterprise enables a non-disruptive migration of LPARs between
systems (Partition Mobility) *
Data mirroring over both storage subsystems with AIX standard tools (LVM Mirror)
SAN connection via 8Gb FC
LAN connection via 10 Gbit / 1Gbit copper RJ45
Use of VSCSI- or NPIV technology for the operating system and data LUN’s
The management of the hardware and LPARs takes place on the HMC
* Requires appropriate support of this technology through the application vendor

OS-DB-Migration
IBM POWER uses big-endian,Intel uses little-endian
OS-DB-migration was necessary
Significant CPU-load on app (!) servers for export / import in platformindependent format, about 15 GB/Core/hour
Parallelization / partitioning of large tables
Test of migration on sandbox system
DB objects created with HANA-Studio or SLT had to be migrated manually (!!!!)

TSM Beta Programm
“TSM ERP SAP HANA on Power“ available with 7.1.3
Direct API call from HANA instead of temporary dump
Participation in BETA-Program
One error found – quickly resolved (stability)
Great cooperation with IBM specialists
Subsequent tests passed without any problems
TSM is now called

SAP HANA Backup with TSM (Spectrum Protect) @ HR Group
Hamm Reno (large retailer in Europe) decided for SAP HANA on POWER
Gained better performance compared to SAP HANA on INTEL hardware
Hamm Reno was the first customer that is in production with Spectrum Protect for ERP for
SAP HANA on POWER
Scenario
Full database backup of production system to tape
Redo logs and development system to disk, later migration to tape
Customer feedback:
"HammReno is using Spectrum Protect for many year to protect their SAP databases. During the HANA
RampUp on IBMs POWER platform we evaluated Spectrum Protect for ERP using early code. It worked
very stable and robust with great performance characteristics, which made us using the product in our
production environment starting with the first day of General Availability on the POWER platform."

Assessment / Impact of Risks
OS-DB migration had to be completed within given timeframe. This was feasible
TSM 7.1.3 was available (GA) on time for go-live
Support for SLT was agreed 10 days prior to go-live
SAP OS/DB migration check service became available on time
HANA-Rev. 94: Error in test system: “Integrated Planning“
SAP Note: 2100049 / 2094791 (or BW SP13)
IBM activated some additional cores (already built in)
No show-stoppers
Timing and project plan were fully in scope
Production migration was flawless33
Tips & Lessons Learned
Check and use DNS aliases
Validate unified names of schemes
Test migration using sandbox system
Evaluate BW patchlevel update before migration
Plan for manual migration of “other“ HANA objects
Perform „Integrity Test“ before export
Configure 10+ cores on App servers
IBM and FUM always reacted fast and with high competency
Also with SAP it‘s a great help to have a personal contact

Summary
Since 2000 HR-Group is satisfied IBM Power customer
When starting with SAP HANA – it was only available as an Intel Appliance - a “foreign object” in our Data Center
SAP HANA on IBM Power is a real Enterprise Solution: Not an Appliance but implemented as a Tailored Data Center Integration (TDI)
The time was right to join the SAP on Power ramp-up program
All IBM POWER8 server configurations are certified by SAP
Smooth Migration to SAP HANA on IBM Power Systems!
42
Next steps
Upgrade from SLES11 SP3 to SLES4SAP (SLES11 SP4) with support from SUSE (done in Jan/Feb 2016)
Full virtualization of Power8 servers with PowerVM
Integration of application stack in SAP HANA LPAR (back to 2tier)
Planned integration of SLES HAE for reducing unplanned downtime
Further SAP HANA projects with SLES and IBM Power Systems
