How Does SAP BW Accelerator Work in Reality??
•
Currently, SAP BW Accelerator performs aggregation and
data selection for the query, all other processing is done
by the OLAP analytical engine
•
Therefore, not all query processing will be dramatically faster
•
In the next SAP NetWeaver release the SAP BW Accelerator will
handle more of the analytics processing, such as “top-5 products
sales,” which is currently done in the OLAP analytical engine
•
SAP BW Accelerator is not used when the result set exceeds 3
million records (max. default)

When the result set is less, the data is sent as one large data package to the
application server (need fast network)
7
The New SAP Explorer and SAP BW Accelerator
The new SAP BusinessObjects Explorer (not SAP BEx) brings together inmemory processing SAP BW Accelerator with the SAP BusinessObjects
business intelligence (BI) search engine
Users can search & explore large volumes of enterprise data to answer
‘on the fly’ questions, discover relationships, and uncover root cause
All business users gain immediate insight without needing assistance
from business analysts or IT. No training required
8
SAP BW Accelerator as a Tool for SAP BusinessObjects Integration
Problem: In the new SAP BusinessObjects
landscape there are two ways to build a
semantic layer (universes) for implementing
data access. Each has its own limitations and
benefits.
The first is an MDX-based universe for OLAP
consumers. This is easy to create and is
based on a SAP BW query. However, it is hard
to merge external (non SAP BI) data using
this method.
The alternative is to build a traditional SQL based
universe, but it is very hard to get access to the SAP
BW data since this by-passes the BI analytical engine
inside SAP NetWeaver BW.
Solution: Implement SAP BW Accelerator + Facade
and you can build SQL universes with SAP BW and
external data.

Wrap-up
11
Compression and TREX
The TREX engine is NOT the same as the traditional implementation
of the search engine.
BW Accelerator comes its own
TREX engine that collects the data.
During the index build, the data
is also compressed using advanced
mathematical methods.
The result is therefore a much
smaller sized index than the original
InfoCube
12
Performance is Near-Linear: Benchmarks
SAP BW Accelerator’s strength
resides in its near-linear
scalability
Performance is measured in
terms of:
1. BW Accelerator
index creation time
2. Multi-user throughput per hour
3. Average report response time
4. Average number of records
touched by each report
13
SAP BW Accelerator currently reads data
from InfoCubes.
DSOs and InfoObjects are still read from
base/physical tables (even when the
InfoObject is indexed as part of master data).

Query Performance Improvements - Real Example of 70 queries
The slowest queries that spent most
of their time on the database side
benefited the most
Overall 36 of 70 queries were at
least twice as fast. Before SAP BW
Accelerator, the average query
execution took 58.8 seconds; after
SAP BW Accelerator the average
query took 17.9 seconds (295%
faster overall).

The major
improvement is
to make query
execution more
predictable and
overall faster
Workbook Performance Improvements with SAP BW
Accelerator
Workbooks require embedding of JavaScripts; can contain multiple queries;
and may have macros, lookups, and internal logic
It is therefore hard to estimate the real
performance benefits of implementing
SAP BW Accelerator
In this real example of 20 slow workbooks, the
average performance improvement for
workbooks was 363% faster
17
Performance Info — SAP BW Accelerator Indexes Build
Times
Creating new indexes (refreshes) can be time
consuming. The build time depends on:
a) The size of the records (length)
b) The number of records
c) The number of SAP BW
Accelerator processors
d) The network transfer speed
In this example, 23 InfoCubes with over 232 million
records were indexed in 90.56 minutes
On average, 2.56 million records
per minute were indexed!

Most Customers Have Found SAP BW Accelerator Admin to Be
Minimal
The Admin work is
done through a
single interface
The admin interface
is available under the
transaction code
RSDDBWAMON.
Health checks for
SAP BW Accelerator
are available under
the transaction code
RSRV
Most companies plan for a maximum of 2-5 days of
SAP BW Accelerator training. You need a maximum
of 1-2 administrators (1 for backup).
20
Health-Checks and Reconciliation
The SAP BW
Accelerator interface
allows you to compare
the data in SAP BW vs.
the indexes. This
means that you can
easily check if they are
outdated.
Other tools include the
ability to run queries to
see if the numbers in
the two databases
match.
21
Proposals and Estimations
The Analysis and Repair options
include many proposals and time
estimation tools that you should
leverage.
The interface can propose deltaindexes for periodic updates (not
complete builds).
You can estimate the run-time of
indexing the fact table of an
InfoCube before you place it into
a process chain or a manual job.
You can also estimate the
memory you need before you
add new records into memory.
22
The SAP BW Accelerator “Reset Button”
The simple way to fix
most issues is to delete
all indexes and rebuild
them during a weekend
Think of this as the
ultimate “reset” button
You can also rebuild
master data indexes

Planning a 6 -weeks SAP BW Accelerator implementation
•
A BWA Project can be completed in 6-weeks.
•
However, due to hardware lead-times (normally 4-6
weeks), most project should plan a 12 weeks duration.
•
The time waiting on hardware should be used on
performance tuning of existing queries and dashboards
•
In the this section we will look at the major tasks of
implementing a BWA solution

Sizing is important to determine the overall system hardware needed.
You cannot use the size of the InfoCubes, since the TREX indexing
also uses compression to reduce overall size.
28
Sizing Is Critical, but Good Tools Are Available
SAP has integrated key sizing parameters for SAP BW Accelerator in the new
Quick Sizer. You can give it a try at: http://service.sap.com/quicksizer (requires
login credentials for the SAP Service Marketplace)
Customer with existing BI systems and data loaded can get good sizing and

is frequently 4-6 weeks.

Some Hardware Options
Operating Systems and Storage
SUSE Linux 64-bit, Intel based
Memory based and file storage (no database for
Accelerator)
Available Hardware Platforms
HP (HP ProLiant and HP StorageWorks)
IBM (IBM Blade Center and IBM Total Storage)
Fujitsu Siemens (FSC Blade Server and EMC Storage)
SUN Microsystems (SUN Blade Server and StorageTek)
The hardware implementation is done by the vendors. Be prepared for
lead times on delivery of large systems (made-to-order is common).

analytical engine is still performed. You should therefore also tune these

& make sure that the data traffic between the database server and the BWA
server is not using old data networks with slow routers and shared switches.

Test the overall solution over a weekend and compare the benchmarks against those
you had in week 3 to document success and possible bottlenecks. Integrate the index
creation times into the existing process chains and monitor impacts.
39
Team Organization
1. Create a small team of three people dedicated to the
SAP BW Accelerator project supported by one Basis
person and the rest of the BW team
2. Hardware team members supported by the vendor
should also be involved in a part-time capacity
3. Overall the SAP BW Accelerator effort should be
combined with a performance tuning project that
also includes building of aggregates, caching, and
query redesigns
40
Testing
1. Make sure you identify real benefits and benchmark
with pre- and post-performance after SAP BW
Accelerator is implemented
2. This requires that all critical performance data is
captured before SAP BW Accelerator is installed
3. You should document the post performance and build
times as early as possible so that you know what the
performance of complex dashboards will be and how
the indexing will fit into existing process chains

7 Key Points to Take Home
•
Plan to order hardware early – Lead times can be long
•
Create benchmarks for workbooks, queries, and cockpits to document
success – Be realistic, not all queries will benefit equally from SAP BW
Accelerator
•
Involve your Basis team and environment management team early
•
Plan for testing and gradual rollout of SAP BW Accelerator to key users
•
