Audi replaces HP/Oracle combo with Power Systems and DB2

German motor giant Audi has ditched its large HP/Oracle estate in favour 
of IBM Power Systems to run its worldwide SAP ERP systems.
 
Audi was running SAP on 12 servers and 24 blades from HP with Oracle 
databases. It has replaced them with four AIX-driven Model 570s and 21 
PS702 BladeCentres. It migrated over 100 SAP systems from HP-UX to AIX 
6.1 and from Oracle 10g to IBM DB2 9.7 over six months.
 
Part of the Volkswagen Group, the company operates eight plants around 
the world producing Audis, Lamborghinis and Ducatis with more than 
65,000 employees. In seeking to reduce costs, tighten efficiency and 
iron out issues it had with its plethora of SAP apps, it decided it 
needed a new private cloud infrastructure.
 
Markus Wierl, Audi AG's service owner of SAP infrastructure, says: "We 
wanted to create a flexible virtualised infrastructure that would enable 
us to grow and add new services without needing to consider the 
underlying hardware or any other constraints. The IBM Power Systems 
offerings were highly attractive because of their mature virtualisation 
capabilities. So we invited IBM to propose two options: one using our 
existing Oracle database, and one with the IBM DB2 database."
 
Perhaps unsurprisingly, IBM got a proof-of-concept together within three 
weeks.
 
  "IBM created an environment that enabled us to compare DB2 9.7 with a 
reorganised Oracle 10g database, both running on IBM Power Systems 
servers, " says Wierl. "The results were clear: storage savings in the 
range of 50% to 70%, and much higher performance when using DB2."
 
A combined IBM and Audi team completed all the migrations with no 
disruption to business at a rate of between two and five SAP systems per 
week over weekends. Oracle DBAs at Audi were retrained in DB2.
 
Between them, Audi's four 570s have with a total of 80 active Power6 
cores. The virtual AIX servers are all clustered for high availability 
using IBM PowerHA. A further 48 Power6 cores are available on demand – 
Audi pays for these as it uses them. The servers have a total of 1.5 TB 
memory, with a further 0.8 TB available on-demand. Of the 21 
BladeCentres, 18 are configured with 16 Power7 cores and three with four 
cores.
 
Furthermore, IBM scooped a deal to host the new infrastructure. Audi 
compared the figures from three major providers and found that going 
with Big Blue would produce 20% to 40% more energy efficiency over four 
years. DB2 compression was a factor, reducing the amount of disk required.
 
The SAP solutions used by Audi include HR, warehousing, financials, CRM, 
logistics and an e-recruitment solution.
