I'm preparing to build a new Windows server for an LMS (potentially LMS + HUM) installation. The LMS is a 300 device license but it may be increased in the future to the next licensing tier (1500 device license - don't anticipate managing more than 500 max though).
My server hardware is a HP Proliant DL140 3G with dual 300 GB SAS drives, a single dual core Xeon processor and 4 GB of RAM.
My question is whether I'd be better served by:
a. Windows Server 2003 R2 (x64 version Standard Edition with Service Pack 2) as opposed to Server 2008 SE with SP1. I'm leaning this way due to the swap file bug / workaround and the feeling that Server 2003 is more mature than Server 2008 (though if LMS was supported on Server 2008 R2 I'd reconsider).
2. Should I drop in another 4 GB of RAM? I know that 2 GB is all that's REQUIRED but would moving from 4 GB to 8 GB help things out on a <300 device installation? (It's < US$200 at Crucial and I have 4 empty slots.)
