Design Tips and OS versions

Raymond Chou, MVP in Malaysia, has a number of tips when designing SCOM.

I don’t disagree with them but you need to caveat these tips with the fact that these are tips for big systems like the blueprint I did for a 5000 agent system.

If you have 31 servers (which is one above the limit for SCE) you would not have a separate DB, RMS and Management server would you? Neither would I have a gateway server as the chances are only one or two servers will be in a DMZ. I don’t think that they would be happy having to buy 4 servers to monitor 31. As the saying goes – size matters.

As a consultant I like to spend time with the customer and find out what they have and what they are trying to do which is where my design questions come in. Unfortunately they don’t like spending as much time with me as it costs them money! And even when you do recommend separate servers the client still wants them all on as few as boxes as possible to save money and so ignores your advice after paying for it.

As for 64 bit versions – 32 bit Windows can support up to 64 GB – it just needs to be Enterprise SP2/R2 whereas 64 bit Standard R2 can support 32 GB and 64 bit Enterprise can support a whopping 2 TB.

The trouble is that the 32 and 64 bit versions are the same price but the Enterprise version is 2 to 3 times more expensive. So if you don’t need clustering 64 bit Standard R2 is the most economical way to get large memory systems above 4 GB unless you have a good deal to get Enterprise edition at a special rate. But even then it is hard to find a server manufacturer not shipping x64 machines and x64 is the future.

The Datacenter option looks like a bargain as it can support up to 128 GB of RAM or 2 TB with x64, is cheaper than Enterprise (as that has 25 CALs in the  price) and supports an unlimited number of virtualized machines. And with SCOM one OML covers the whole machine as it is per physical device. What a bargain.

On SQL 2005 both Standard and Enterprise support up to the maximum of the OS but standard only supports 4 CPUs and 2 node clustering but is one fifth of the price.

However if you are going to use Standard edition look at buying the integrated license with SCOM and save a lot of money (and no need to count CALs or CPU licenses). The only caveat is that this is the only system that SQL can be used for but for most people that is not a problem.

No mention is made of 32 bit v 64 bit in any of the SQL licensing pages so I am assuming that they are the same price like Windows 2003.
