Disks Requirements for BPC 10 NW application server

[Former Member]

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	40
Multiple UJBR backup file/ Transaction data export	10	20
ST12 Traces/SQL traces: 2MB per trace* (500-1000 traces)	1	2
Work process traces (high trace level): 30MB per trace * 100 work processes	3	3
SQLDBC traces: 20MB per trace * (100- 200 traces)	2	4
Others Programs/Files/Free space	25	50
Total Size	139.5	294.7

 

 

For calculation of page file requirement, please refer to document “Virtual Memory Required by SAP System Components”

http://scn.sap.com/docs/DOC-41587

 

SAP System components	Virtual Memory Needed	GB
Central Instance	500MB+ 1 to 2 times PHYS_MEMSIZE+ 2.5GB + 250MB Per work process	92-156
SAP Agent(SMD, SAP Host Agent)	Approx. 300 MB	0.3
Operating system	5 to 10% of RAM of physical host, minimum 3 GB	3.2- 6.4
MDX Parser (For BPC/BW system)	250MB per process * 20?	5
Third-party applications (backup programs, hardware agents, etc.)	Depends on third-party application	2
Total virtual memory needed	Total sum of virtual memory	102.5 -169.7
Page file size needed	Total virtual memory – RAM	38.5   - 105.7

 

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.
