High availability SharePoint with F5

Hi,

 

Our F5 configuration was set up by network team and so far everything seems to be working. We have 2 x Web servers in the app pool but I can't really verify if F5 is, 1. load balancing SharePoint, 2. providing high availability for our environment.

 

The other day I've had to reboot one of the web servers so I took that opportunity to test HA, to my surprise it wasn't working. I was hitting the web server that was rebooting. I was told by network guy that he set F5 up according to Deployment Guide version 3.2 - Deploying the BIG-IP system v11 with MS SharePoint 2010 and 2013. The configuration was created using iApp.

 

I don't have access to F5 but I need to verify a setting(s) for HA if there's one. Can anyone please help me with this as I need to go back to the network team and point this out?

 

Many thanks.

    Hi James, can you check that the Action on Service Down option on the SharePoint LTM pool is set to "Reject"? This will send a reset to the client as soon as the pool member is marked down. I see that the iApp is not setting that as it should.

     

    thanks

    I would also look at the health monitor's interval and timeout setting, it could be a big value. If the interval is 30 seconds, chances are the timeout is 91 seconds, which means it wont mark it down for over a minute and half! You might want to finetune that a bit, to a lower acceptable value for your environment.
