Guidance on dedicated Distributed Cache SharePoint Server

Hi All,

We had issues earlier on our web end servers for distributed cache service and page loads took 40 seconds to 1 minutes. Thats why tuned it off.      

Now we have dedicated distributed cache SharePoint server and it will manage all the 4 web front end distributed cache services.

Q: In this dedicated distributed cache SharePoint server, we are planning to just turn on the distributed cache services only and this server serve all the 4 web front end social features. Do we have open all Distributed cache services ports 22233-22236 for all WFEs?

Q: Do we have best practice from Microsoft about this? or any blog that outlines this? 

Please advise. 

Thank you. 

Cheers,

Yes, these ports are opened when the server is added to the SP farm for first time.

Also on design, check these articles:

Hi Mohit, 

Thanks for your valuable inputs.
So we need to same thing for Office Web Server 2013 dedicated server with port 803 for WEFs as servers. 

Is the same logic for server-to-server authentication between SharePoint farms like dedicated  Distributed cache server? 

Thank you.

Yes, SharePoint consumes office web apps services using ports 80/443. Port 809 is for private traffic between the  Office Web Apps Servers themselves.  

Thanks

Hi All, 

For Distributed Cache server, there are couple of Technet blogs outlining the trickiness of DC configuration and SharePoint team warns if we did not configure the DC server we need to rebuild the farm. 

Additional considerations DC farm is not to install the Search service, Excel Services, project services. We will definitely will consider while installing DC on the farm. 
Another blog from Idera gives useful tips to configure DC.
After we have installed the DC SharePoint server, is it advisable to enable the DC service from farm wizard and will it take care of all the SharePoint servers in the farm? What is best practice for dedicated DC server? 

Any help you be greatly appreciated.

Hi Sandy

When you run the GUI version of product configuration wizard on the SP server, its auto added to the distributed cache service farm. If you do not intend the joining server to be part of DCS farm, you need to use the skipRegisterAsDistributedCachehost parameter with the  Connect-SPConfigurationDatabase Windows PowerShell cmdlet, or when running psconfig.exe at the command line.

My understanding is that you already have few servers in SP farm and you are looking for steps to configure a dedicated cache server. If it is so, you need to install and configure SP on the dedicated server and then remove distributed cache service on other servers in farm. Since SP server gets auto added to distributed cache service farm on joining existing SP farm, you don't need to worry about that.

Here' are few links worth visiting:
