We are looking at replacing a Microsoft SQL server. SQL is being used by one software. We have approximately 60-70 users. The current server gets overloaded because of disk usage, Processors and memory are fine. Plenty of space just has performance issues, the performance monitor shows the physical disk(Raid 5) is having a hard time keeping up. My question is.....What is the best way to configure the hard drives/controller for a new server? We would like to virtualize it and use the other half as a domain controller or image one of our older server and move it over to the VMware server. Not familiar enough with VMware to know the best practice in this scenerio. How much memory should we get assuming we virutualize? Will both virtual machines be fighting over the same hard drive resources?
