DC RUM AMD Load Sharing on different versions of Redhat


Are there any known issues with running different versions on a load shared set of AMD servers? We have a Redhat 6.6 and 6.5 server that we want to configure in a load share, and would like to know if this is doable without a full rebuild of the 6.5 server. Thoughts?

This will be on DC RUM 12.4.2



Hey Erich,

Are you asking if you can have two different versions of RedHat AMDs both processing traffic for the same CAS/ADS cluster? Do you mean load sharing from a gigamon -> AMD perspective or AMD + AMD -> CAS?

Right, the same CAS/ADS cluster. These AMD's will be configured for load sharing on the same data feed coming from the gigamon tool ports.

Okay, I can't speak to known issues, but I don't foresee an issue here. I have previously ran two different RHEL builds (5.6 and 6.5) and it didn't seem to make a difference.

No there's no technical limit stopping you. There may be some performance/compatibility/security issues arise, from different kernel and library versions on Red Hat.

It'd make sense from a manageability perspective to have all AMDs at the same versions.

You shouldn't need to "full rebuild" to get from 6.5 to 6.6. It can be done easily online, or still pretty easily offline using a 6.6 ISO image/DVD.

Using a guide like this: you can mount a 6.6 ISO file, and upgrade locally without internet access required.
