I’ve had numerous emails about this question which can be found in my VCP410 Practice Exam. So I think it’s time to sort this out once and for all.
According to the VMware document: ESX and vCenter Server Installation Guide page 16, it clearly states;
Memory — 3GB RAM. Memory requirements might be higher if the database runs on the same machine.
According to Scott Lowe’s new book: Mastering VMware vSphere 4.0 in Chapter 3, page 61 under “Sizing Hardware for vCenter Server” he says;
2GB or more.
According the VMware vSphere 4 Install, Configure, and Manage course books they says;
2GB, more if you run the vCenter Database locally.
So what is it?? I want to get the questions/answers to my practice exams 100% right, as there would be no point if I was giving out the wrong answers.
Please comment or contact me directly if think you can help answer this question.
