I've created a MEDIUM NON-HA MinRole Farm (4 servers) Farm

  • Application (Central Admin)
  • Front-end (WFE 1)
  • Distributed Cache
  • Search

I've been running into some issues that point to the WFE being overloaded recently and was wondering if I could convert my

  • Distributed Cache to Front-end with Distributed Cache or the

or the

  • Front-end to Front-end with Distributed Cache and Distributed Cache to Front-end with Distributed Cache

enter image description here

Would this make a difference in general performance? And is it as easy as switching the role in Central Admin?

Any advice is greatly apricated.

Provided you have a load balancer in front of your FEs, yes I think that would be the right approach -- with a farm that otherwise has no high availability, there's no reason to separate out DC onto a dedicated server as your environment isn't large enough to call for it.

You could make your farm highly available by making the backends App + Search, though you'd need to modify the Search topology via PowerShell.

And if your SQL Server isn't highly available, you'll want to fix that, too.

  • Thanks. that does make sense. Out of experience is it that simple to just switch the DC to a WFE with DC? And in regards to a highly available SQL server. How would i got about finding out if I have one? Thanks!

  • Yes, DC -> DC+FE is easy. You need a load balancer in front of your two FEs and point your A/CNAMEs at the VIP. For SQL, ask your DBA if you have Mirroring or AlwaysOn Availability Groups set up and validate SharePoint is configured appropriately. If not, follow docs.microsoft.com/en-us/sharepoint/administration/….

  • So I just spoke to our DBA, and he said that a load balancer is not an option at the moment. Let me ask you this. Is a custom role advice? what if i make my DC a custom role and enable a few extra services to offload the FE?
