configuration - what is SQL Server 2012 required memory for bigger databases -

-

i reading through this msdn document check whether servers resources enough or not. found interesting requirements not have further clarification online,

recommended: @ least 4 gb , should increased database size increases ensure optimal performance.

can body give more information on how memory should increase when data increase? (ex: each 10gb we'll need 1gb of memory or each 100 table/sp we'll need additional gb)

there not answer question. required memory depends on many factors , 1 of them database size.

number of users, volume of server request, concurrency, codes (like etl , procedures) , many more factors involved.

the right way find out how memory need, monitoring server using tools , performance monitor on windows.

you need see if memory bottleneck or not. if bottleneck disk , cpu or network bandwidth, adding more memory won't , not required.

edit:

data size alone doesn't mean anything. may have terabyte database reports , applications work on small chunks of data @ same time. note having more ram, helps sql server data caching, sorting , other internal data processing. if report read 100k records, don't need large amount of ram. if report processes large volume of data (aggregation, sorting, grouping), having more ram improves performance.

if looking formula determine required ram per each gb data, don't know formula. may ask dba site or more research.

hope helpful.
