[gpfsug-discuss] Spectrum Scale protocol node service separation.

I think only recently was remote cluster support added (though we have been doing it since CES was released).

I agree that capacity licenses have freed us to implement a better solution.. no longer do we run quorum/token managers on nsd nodes to reduce socket costs.

I believe socket based licenses are also about to or already no longer available for new customers (existing customers can continue to buy).

Carl can probably comment on this?

The docs say: “CES supports the following export protocols: NFS, SMB, object, and iSCSI (block). Each protocol can be enabled or disabled in the cluster. If a protocol is enabled in the CES cluster, all CES nodes serve that protocol.” Which would seem to indicate that the answer is “no”.

This kind of thing is another good reason to license Scale by storage capacity rather than by sockets (PVU).  This approach was already a good idea due to the flexibility it allows to scale manager, quorum, and NSD server nodes for performance and high-availability without affecting your software licensing costs.  This can result in better design and the flexibility to more quickly respond to new problems by adding server nodes.

So assuming you’re not on the old PVU licensing model, it is trivial to deploy as many gateway nodes as needed to separate these into distinct remote clusters.  You can create an object gateway cluster, and a CES gateway cluster each which only mounts and exports what is necessary.  You can even virtualize these servers and host them on the same hardware, if you’re into that.

Hi,

I seem to be unable to find any information on separating protocol services on specific CES nodes within a cluster. Does anyone know if it is possible to take, lets say 4 of the ces nodes within a cluster and dividing them into two and have two of the running SMB and the other two running OBJ instead of having them all run both services?

If it is possible it would be great to hear pros and cons about doing this 😊

Thanks in advance!
