server roles are split among 3 tiers
all 8GB RAM each on 3 x VMs
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
