For effective use of this slide set, we strongly recommend to read through the preface!
•
This slide set is primarily intended as a working tool for the SAP Competence Center; providing support for
our partners and customers.
•
Each of the SAP solutions presented is based on two certified HP ProLiant servers. These proposals are
intended to provide a general reference only; however, these proposals do not replace customer specific
sizing!
•
Mixing the different SAP applications might require different server & storage configurations as proposed in
this guide.
•
This is not a marketing document to position different HP platforms with regard of SAP configurations – it is a
tool for daily sales work.

• The term CPU is equivalent with socket or processors such as a two CPU Quad Core server contains 8 Cores.
• For availability and performance reasons, HP recommends for SAP ProLiant servers a minimum configuration of two
processors or sockets.
• Depending on customer requirements in relation to data throughput (LAN; SAN); memory extension and scalability of
the server it might be advantageously to choose 4-socket servers as they provide more PCI-slots (data throughput) and
memory slots as 2-socket machines.
• In smaller system landscapes, we offer more powerful server systems than required by SAPS. With Intel Xeon or AMD
Quad Core technology the systems offer huge CPU reserves.
• Although one CPU might be able to cover system requirements of smaller systems (especially for non productive
environments), we recommend using two CPUs.
• For clarification – one 2.0 GHz Quad Core CPU costs about 250€ list price. Also bear in mind that two
CPUs improve server memory addressing and redundancy!
• The sizes of the test- and quality assurance systems are related to the size of the given production system and serve as a
general guide.
• The database sizes are based on SAP CC experiences.
• We strongly recommend to get in touch with our StorageWorks specialists in our SAP CC regarding the following topics:
• Selection of appropriate storage array like SWD All-in-One, storage blades, MSA, EVA or even XP, based on
customer requirements
• Backup & restore and availability concepts considering recovery point, recovery time and general availability
• Consolidation of backup and the various associated topics like tape backup, virtual tape libraries, disk-assisted
backup, local and remote mirroring including cluster integration with CLX or MetroCluster
• Value-added tax (sales tax) is not included in the prices (see separate excel worksheet) listed.
When running business critical processes on an SAP production system, you have to customize
and develop on a separate SAP system, called the development system. Upon completion of
a change, the change needs to be transferred to a
•
quality assurance system (also called test system), where the changes will be tested with
master data, ported from the production system. When it has been verified that the changes
function correctly, these changes will be ported from the development system to the production
system. Consequently, SAP recommends the implementation of at least three systems in every
SAP project.
•
On big systems, we recommend the additional installation of a lab system for testing new
software versions and operational concepts. Another critical task handled by the lab system is to
verify if backups from the production system can be restored, implying that the
database size needs to be the same as that on the production system.
•
If your production system is deployed on a cluster, SAP strongly recommends the
installation of a lab system which is also operated in a cluster.
•
HP recommends to provide high availability for production systems and to use a cluster generally
for 300 users and above.
• The following block diagram is user based. A user based sizing can be done by HP Sizer or SAP
Quicksizer. Quantity based (requires expert know-how) sizing can only be done by SAP
Quicksizer or SAP CC. The description refers to concurrent users; that means SAP users effective
working on the system and not the number of SAP licenses or logged-on users. This is a good
approximation; and this is verified by our experience; is a ratio of one concurrent user for two SAP
licenses (50%).
• As every SAP system has to be customized to the individual customer requirements, it creates
variable load. To provide for adequate system reserves, we estimate a minimum of 10 SAPS (SAP
Application Performance Standard) for each concurrent user that is equivalent to a medium SAP SD
(Sales & Distribution) user.
• The performance of the servers (CPUs) has increased during the last years; you have to put
adequate memory into the servers. A rational starting base for production systems is to calculate 4until up to 8 GB per Core. Be aware that you only get the feasible SAPS values of the respective
servers when using sufficient memory (for instance 32 GB for 2- socket- & 64 GB for 4- socket
servers).
• The size of the database is based on our experience and best practices. On smaller databases we
have to prioritize performance instead of capacity.
The key to improving IT operational effectiveness is to coordinate activities across all the components of your infrastructure.
HP Service includes consistent proactive and reactive services across the whole infrastructure, including hardware, software
and specialized solution support for SAP environments.
Reactive support (Support Plus 24) is delivered through HP’s global support infrastructure. Reactive Support Services
focus on fast and full restoration in the event of a failure, so any problems are fixed quickly and cost-effectively. HP provides
industry-leading call-to-resolution commitments for hardware, including a six-hour call-to-repair commitment for hardware.
HP’s Global Solution Centers are located in key points around the globe, so they can work on any issues 24x7, 365 days a
year.
Proactive onsite support services, delivered by availability and technical experts at your site, help you continually
improve your IT operations. These services are based on industry standards for IT service management, such as ITIL, and HP’s
own experience in managing mission critical business applications. With a proactive approach and remote support
technology HP helps you identify, diagnose and resolve problems before they cause downtime, through monitoring and
analysis of your mission critical environment.
HP Proactive 24 Service helps to improve the stability, availability, and operational effectiveness of your IT environment
through a combination of industryleading technical assistance and proactive account services that cover the entire IT
infrastructure.
HP Critical Service integrates proactive and reactive services to improve availability and performance for businesses where
downtime can be disastrous. Critical Service combines proactive onsite expertise from HP-certified high availability experts,
24x7 priority assistance from HP’s worldwide missioncritical response centers, and proactive remote support tools.
Depending on the size and the complexity of an SAP environment, we propose here a generally adequate service level.
We highly recommend getting in touch with a Service Solution Architect to select and configure the specifically appropriate
service level.
