Server Design & Performance:
•
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.
