Let’s use a typical standalone BPC application server for example:

OS: Windows 2008 server R2

Number of CPU Cores: 20

Memory: 64 GB

Number of work process: 100

If there is no other large application installed on this server, typical size required for your BPC 10 NW application server would be like:

Mid-Low Range (GB)

Mid-High Range (GB)

OS/Program files/User folder

20

30

OS Page file

38.5

105.7

Temp installation files/Patch Upgrade/Transport logs/Etc

20

40

SAP BPC 10 NW Folder

20

Multiple UJBR backup file/

Transaction data export

ST12 Traces/SQL traces:

2MB per trace* (500-1000 traces)

2

Work process traces (high trace level):

30MB per trace * 100 work processes

SQLDBC traces:

20MB per trace * (100- 200 traces)

So from the calculation above, hard drive size requirement for a typical BPC application server is between 140-300 GB. For larger BPC server, you have to increase size of hard drive requirement.

I would recommend go for 500 GB if you have very limited knowledge about your feature need and system maintenance work.


200 – 320 GB hard drive may work well if you know what you need and how to manage your BPC application server.

Fixed Hard Drive Size <200 GB is not recommenced. Cost of hard drive is a relative small percentage in the server, do not make mistake here.
