Dynamics NAV 2013R2 High Availability

(0) ShareShare
ReportReport
Posted on by Community Member

Hi everyone

I've been searching the web for information about some topics but couldn't really find anything useful regarding NAV high availability, fail over cluster etc'...

So here are my questions, hopefully some of you with better experience can enlighten me:

1. What are the options for installing NAV Services on multiple servers against the same Database for high availability?

2. Regarding the first question is it possible to have an automatic clients fail over in case one server fails, also is it possible to have an NLB between those two servers?

3. What is the recommended concurrent user count for a single service of NAV?

4. Would load balancing the web-client be a straight forward procedure like an NLB between 2 regular IIS websites or are there other considerations that should be taken in account?

A big thank you for anyone who can help!

Michael.

    Hi.

    1. Multiple servers against a SQL Database Cluster would be the way to go.

    2. You would use a NLB between x numbers of NAV servers

    3. Depending on user type and the server size.  NAV Service is 64bit and will use large machines.

    4. You can both loadbalance several IIS servers and each IIS server can use NLB to connect to x numbers of NAV servers
