Configuring the Hardware and Installing Windows NT 81
• It is a direction of SAP to format each new partition for your SAP R/3
installation with the NTFS file system and a cluster size of 4096 bytes.
• Set the parameters for the file system and cluster size and press OK to format
the partition.
• Repeat the steps for every new partition.
Note: We recommend that you save the new disk configuration with the Repair
Disk Utility as described in 2.13.10, “Repair Disk Utility” on page 87. We
recommend you to repeat the procedure after the R/3 installation.
2.13.7 Tuning Windows NT Parameters for SAP R/3
Windows NT Server 4.0 is one of the few operating systems that have the ability
to self optimize. This can be deceptive, as it will only administer certain aspects
of the operating system. Self tuning of the operating system focuses on page file
and memory management optimization. In the SAP R/3 installation manual, SAP
recommends and determines settings for several of these parameters.
2.13.7.1 Multitasking
Windows NT as a multitasking operating system can run several tasks or
processes at any one time on the server. Each task gets a time slice of processor
time at regular intervals. This gives the appearance that all processes are running
simultaneously.
In multitasking systems, there are two types of processes usually running at any
one time. These are foreground and background processes.
Foreground processes are those that are running in a GUI or full-screen session
at the server console, and background processes are thosethat do not require a
user interface and service server request without user interaction on the server
console.
Windows NT will preemptively prioritize the process threads the CPU has to
attend to. However, you have some control over the rules governing this process.
