Just to expand a little on this topic.... If my memory servs me well, the limit on the number of CIs is around 4 million if you keep the default settings on FD/TD. At around 4 million CIs, the JRE hits the 2 GB limit, and the discovery can't run no more.... The 2.6 million CI limit on the docs is a conservative estimate, plus they are taking into account all the relationships too.
When you hist the 2 GB limit, you need to partition the discovery. If you have 10 millions CIs, you'll need 3 or 4 discovery servers, configured so the discoveries don't overlap. Typically each discovery server is a 4 GB memory dual processor server, that is what is recommended. -Guillaume -----Original Message----- From: Guillaume Rheault Sent: Tue 11/18/08 11:46 AM To: [email protected]; [email protected] Subject: RE: Max CIs on a Discovery server The real hardcore limit is the JRE running under the discovery tool, that can only grow to 2GB. You will need to have multiple discovery servers if you hit that 2 GB limit -Guillaume -----Original Message----- From: Action Request System discussion list(ARSList) on behalf of Rick Cook Sent: Mon 11/17/08 11:16 PM To: [email protected] Subject: Max CIs on a Discovery server Am trying to size discovery hardware, and ran into an issue. BMC's docs say that the limit per server is 2.6 million CIs, but after deeper questioning, that's just the highest number they tested, not the highest number a given server will actually handle. Does anyone have any real life experience pushing more CIs than that through one Foundation Discovery service into the CMDB? If so, I'd appreciate knowing your hardware, settings, performance stats, etc. We're looking at about 10 million. Thanks!
