Sharepoint 2013 and RAM
Hi,
server roles are split among 3 tiers
all 8GB RAM each on 3 x VMs
apps
web
sql
Now "out of the blue" the memory was saturated on apps and sql - so after a fight i convinced consultants to up to 16gb on both - and the problem immediately resolved. They were adamant that it was not ram and ignored my request and spent 6 days troubleshooting other reasons for poor performance. It was clear to me it was swapping to disk,
now they come back and argue that SharePoint 2013 - in separated tiers/vms we have should run on 8GB even less - saying 2GB should suffice for 200 user small database. 1 saying he runs on his laptop with 4gb :) - The bottom line is they are trying to deflect responsibility for undersized I believe. Now I have the manager here supporting them saying microsoft size limits for an organization and design that we have is in fact 4gB on each VM will run fine.
What I require is some expert view on RAM for SharePoint - I'm aware of search and roadrunner memory issues - However they are denying this was cause. - So what are other sharepoint IT people seeing out there for sharepoint 2013 when it comes to RAM and CPU - for small DB and 200 users.
Great if I could get several responses - thanks also its sql 2012 on own vm

thanks the 3 tier 12GB its a little unclear if thats 12 GB each for the 3 servers - or 4gb each total 12GB?
I've always found SP2013 to be very memory hungry. I'd say the metric is for each server.
It's definitely for each server; there's no statement that it's one server per tier. Tell your consultants the published guidance is 12Gb (Though I'd have gone for 16Gb from experience).

The charts in the top half of this article clearly indicate that the memory amounts mentioned in post above are accurate, (Rainer's being an excellent post). The only way your consultants can come to the conclusions that they have come to is if they have problems reading and understanding either simple charts or difficulties understanding American English.
Hope that helps,
