Figure 45. Page File Size and Distribution
You can set the Initial Size and the Maximum Size of the paging file for a specific
drive. SAP recommends a page file size at least three times as much as your
main memory. This is valid for all R/3 application and database servers. If you
install an R/3 central server (database + application at one machine) calculate an
additional 500 MB for the page file size.
For example, if you installed 1024 MB of main memory in the Netfinity 7000 then
create a page file size of 3072 GB for an R/3 application or database server, and
a page file size of 3584 MB for an R/3 central server.
It is not necessary to make changes to the registry size and it will only waste
space if you increase it unnecessarily.
A feature of the NT virtual memory system is that it allows multiple paging files to
be created. A way to get much better performance from your virtual memory
system would be to establish paging files on more than one drive or on several
logical RAID drives in different arrays. But if they are simply different partitions on
the same device or simply different logical drives in the
same array, then creating
multiple paging files will actually degrade performance.
Note: Avoid placing a page file on the same disk drive together with I/O-intensive
SAP R/3 files, such as database files or online redo logs.
