We are planning to replace our current server with a new one. I have two questions regarding a new server for optimal results.
First one is the operating system, What si recommended at this point, ubuntu 6 or 8? Currently we use 6, if we use 8 on our new server, can the backup be restored to Ubuntu 8?
Second one is the disk configuration. What is the optimal configuration for Zimbra. We do need a lot of storage, we would like to support 200 accounts with a limit of 2GB per account. The backup should run also of course. We our self thought that you use a raid 5 configuration for the store and the backup directory's. And a raid 1 for the OS and the mysql database. Or should everything be on one raid array?
Could someone advise me in what to use?
