Cluster Without StorEdge

Hi .,

I am new to clustering.

We are having two Sun Sparc 490 R servers with Solaris10 installed

which we are planning to configure as a Two-node cluster.

Can anybody tell me whether is it possible to install the two node cluster without any storEdge..

Thanks & Regards

Hi,

yes and no. You can configure a Sun Cluster without any StorEdge, but not without any shared storage. Reason is that the cluster uses a quorum algorithm to decide which part of the cluster will survive after an outage. And this only works with an odd number of votes. Now the nodes have one 1 vote each, where do we get the 3rd vote from. So, add a 3rd server or a shared device.

It is all documented in http://docs.sun.com/app/docs/doc/819-0421

Please check docs.sun.com as Hartmut suggested. It is all documented there.

You can install Sun Cluster software for free on as many systems as you like. However, as soon as you need support, i.e. you are running on a production cluster, you will need to buy the licenses and get a support contract. You will also need to have your installation validated and it would be a good idea to go on the training course too.

However, if you are just a developer, then it is free to use (as you probably don't need any support).
