1 Agenda 7 Hints from the field: how to make BI- Accelerator
work for you Sizing and Implementation Management and Costs Slide 2
2 Hint #1: Customer experiences - BI Accelerator is simple to
install BI Accelerator has been simple to install and operate for
established SAP BI teams You use process chains to maintain the HPA
engine after each data load HP, Sun, Fujitsu & IBM have
standard solutions ranging from $32K to $250K+ that can be
installed and tested in as little as 2-4 weeks (+ SAP license fees)
SAP BW Any tool Breaking news: 32 Gb Blades are now certified by
SAP (July 2008) Slide 3 BIA Currently reads data from InfoCubes.
DSOs & InfoObjects are still read from base/physical tables
(even when the InfoObject is indexed as part of master data). Hint
#2: Performance is near-linear: Benchmarks BIAs strength resides in
its near-linear scalability. Performance is measured in terms of:
1.BI-A index creation time 2.Multi-user throughput per hr.
3.Average report response time 4.Average number of records touched
by each report. Slide 4 4 The BIA should be sized for critical
applications. Most companies use BIA only for Production, while
others have a complete landscape A Real Customer Example from
September 2008 Slide 5 5 SAP has integrated key sizing parameters
for BIA in the new QuickSizer. You can give it a try at:

good tools are available Customer with existing BI systems and data
loaded can get good sizing estimates by running the SAP program
available in SAP Note: 917803 Slide 6 6 Hint #4: Currently, the BIA
performs aggregation and data selection for the query, all other
processing is done by the OLAP analytical engine. Not all query
processing will be dramatically faster In the next SAP NetWeaver
release the BIA will handle more of the analytics processing such
as top-5 products sales which is currently done in the OLAP
analytical engine. Hint #5: SAP BIA 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). How does it Work in reality?? Slide 7 7
Many companies, have spent 2-5 days in BIA training (total for 1-2
administrators) and a work through a single interface: RSDDBIAMON
(Checks available at: RSRV) Hint #6: Most customers have found BIA
Admin to be minimal The training & admin to run BI-Accelerator
has proven to be minimal. Training is included in the SAP courses:
BW310, BW360 & in the on- line course BW361 In the past, SAP
has also offered a 2 day workshop called BI Upgrade &
Accelerator ( WNABIA). Slide 8 8 Once you exceed a few hundred
critical users and/or 3-4 Tb of data you should seriously consider
SAP BIA Hint #7: BIA is becoming mainstream BIA is no longer
something exotic. Many of the large BI systems have already
implemented BIA and many more projects are under way in Europe and
in the Americas. Some of SAP reference clients
