Contact Red Hat, they'll give you a 30 day trial. That's how we ended up evaluating the Zimbra clustered.
Or, if you don't want to do that, you could try Centos4 for evaluations sake.
Thanks for all immediate reply,
I had setup opensource zcs 4.5.10 on rhel5 (i had rhel5 licence ) for one customer with 100 account in production envirnoment but now, For online
backup and clustering and HA we are planning to upgrade with NE
But clustering is not possible in RHEL5, only possible in Rhel4, but again we don't have licence of RHEL4 (for Redhat cluster suite) .
IF I want to have all the features ( clustering, online backup, HA etc ) of zimbra what will be best alternative to do ?????
please help !
what is the best thing to do in these situation.
The answer has been posted multiple times. Purchase RHCS4 and NE. Clustering is only supported in that version, and online backups are only available in NE.
