moving M$ SharePoint Portal Server 2003 from BIG-IP v4.x to v9.x

The version 9's are very different to V4 and there are some basic config's to apply before you even start adding VIP's, Pools, IRules etc.

 

 

I recently upgraded a number of them and we had an F5 consultant and another 3rd party baffled for ages becuase of severe performance and strange issues that we had not seen in the older v4's.

 

 

It sounds like you are going through the same thing, although it might not be spot on, I'd definately create or change the TCP and FastL4 profiles:

 

 

 

Logon to F5 and Select Virtual Servers > Profiles

 

 

TCP Profile

 

Select Protocol and TCP

 

Now create a new profile called MSSP-tcp based on the parent tcp profile:

 

 

Proxy Maximum Segment = enabled

 

Proxy Buffer Low = 131072

 

Proxy Buffer High = 131072

 

Send Buffer = 65535

 

Receive Window = 65535

 

Bandwidth Delay = check custom

 

Neagle’s Algorithm = check custom

 

 

Click on Finished.

 

 

FASTL4 Profile

 

Adding the MSSP-FastL4 profile(used for ALL rule and preventing sessions timing out) that prevent the need to keep authenticating!

 

Make sure you check Idle Timeout=indefinate ENABLED!

 

 

Now configure your sharepoint resources to use the newly created profiles.

 

 

Out of the box F5's do not alway work first time in my experience, they are a happy medium......so get the basic(rule for all!!) config in place first then start adding your resources!

 

 

Good Luck
