I'm working on specs for some servers that will run MS SQL server. I have discovered some interesting things about memory.

























FeatureDetailsFAQGlossary
System RAM, or memory, refers to the amount of data that can be stored on its journey from the hard drives to the processors, and vice versa. With more RAM, the processor will have to retrieve information from the hard drives less often, speeding the overall performance of the system. While some applications, such as email, require more RAM than others, all applications can benefit from increased memory. Dell servers feature DDR2 memory, which enables systems to improve performance and reduce power consumption.Select the right amount of memory based on your application and number of users4GB8GB16GB+File sharing/print50-200 users200-500 users500+ usersMessaging and Collaboration – Email50-200 users200-400 users400+ usersWeb Server/Caching200+ usersInfrastructure/Systems Management200+ usersDatabase50-150 users150-250 users250+ us…
