R80.30 ClusterXL with 2.6 kernel and 3.10 kernel

One of our customers has a failure in the hardware of a ClusterXL gateway. He wants to use a new server HP DL 380 G10 with an old server HP DL 380 G8. The idea now is to use a new 3.10 kernel on the G10 server.

Now the question?

Is it possible to use a 2.6 kernel on the HP DL 380 G8 and a new kernel 3.10 on the HP DL 380 G10 in a ClusterXL?

Check Point's ClusterXL Admin Guide says:

Important! The hardware for all cluster members must be exactly the same, including:

  • CPU
  • Motherboard
  • Memory
  • Number and type of interfaces

 

So you can't configure a Cluster consisting of two different servers. At least not one that is supported.

Thank you, I know. But had already received other statements in tickets from Check Point.

My feeling was more like no!

Hi @Danny,

Did you test that?
Does it work without any problems?

The customer also orders a new second G10 server. We would only do this for a few days.😀

I think the ClusterXL version should be identical on 2.6 kernel and 3.10 kernel. Thus, the requirements for a cluster should be met.

The interesting question is the support of this combination.

If need be, I'd rather have a statement here from Check Point.

Re: R80.30 ClusterXL with 2.6 kernel and 3.10 kernel

The admin guide clearly states 'the hardware must be exactly the same‘ and yours is a G8 and a G10 server, so I think it‘s clear that this wouldn‘t be supported.

Re: R80.30 ClusterXL with 2.6 kernel and 3.10 kernel

Like I said, I know that.

We just need to bridge a few days until the new server arrives:-)

Ok, then test it out and let us know.

I'm going to try this in a maintenance window:-)

Just has to run until the new hardware arrives.

Regardless of this request we could discuss these parameters in another post.

From my point of view only a few parameters are technically interesting in a ClusterXL environment:

CPU -> Equal number of cores -> Sync core number (CoreXL) of a session from one session tabel (active gw) to the standby sessin table (standby gw) => ok!

Memory -> should be equal => ok!

Network Interfaces -> same number of used interfaces in cluster => ok!

Motherdoard -> ??? why should it be the same?

But as I said, that should be discussed in another post.

Please pay attention to the word: including.

Check Point posted just a short listing of hardware devices, not a complete list.

Heiko as long as you have all those configuration elements matching (indicated with ok!) my gut is that it will work fine as I don't see how ClusterXL would be able to freak out over any other differences.  Definitely not supported though...

@HeikoAnkenbrand and all, motherboard is important because of chipset. Most importantly, the proposed configuration will not be supported. 

To the topic starter, as mentioned above, you cannot run such a cluster.
