Hi,

The processor and memory information of system requirements (1) is written as a minimum requirements?
As a small start, 4Core CPUs and 16 GB RAM is enough to be accessed by  100 - 200(2) concurrent users ?
If 100-200 concurrent users will access, how much resources does RELM need as a small start ?

1 Rational Engineering Lifecycle Manager 4.0.5 Detailed hardware requirements
http://publib.boulder.ibm.com/infocenter/prodguid/v1r0/clarity-reports/report/html/hardwareReqsForProduct?deliverableId=1371064297531&osPlatforms=Linux&osPlatforms=Windows
Disk Space:5 GB of disk space for installation & run-time logs.
In addition, 40MB disk space required per 1000 resources indexed (at least 100 GB recommended for typical deployment).
Memory :16 GB RAM.  Swap space equal to twice the physical memory (recommended).  (More memory improves performance; the minimum memory depends on the number of concurrent users, the amount of data being requested, and the size of the database.)
Processor : 4-core CPU, 2.2 ghz

Hi Natsumi,

These are minimum requirements for a successful deployment.  We wouldn't recommend trying to support 100 concurrent users with a smaller spec.  

For a very small deployment (a test demo with just a handful of users) then it's possible to run with 8GB RAM and 2 cores, but that would not be suitable for a production deployment, and certainly not for 100-200 concurrent users.

I hope that helps,

John
