Red Hat Clustering
Hi guys, i have a new client that want to install zimbra on a Red Hat with clustering, but he asks me if i knew any successful story about it, how it works, how easy it is to administrate, so if anyone had done it, please answer in the forum or send me an email email@example.com i'll apreciate it a lot, thanks guys!
Zimbra Cluster is the way if you need HA for your mailbox. I have setup 1+1 all-in-one cluster (50 users) and also 2+1 mailbox cluster (2000 users). FYI, the documentations available at the support portal help me through it. From my experience, the only thing that need further documentation are regarding zimbra SAN partitioning; i meant details of the space needed of all directories based on users/mailbox quota. So far, I haven't encountered any confusions/issues except the SAN partitioning part.
All of the above system running zimbra 4.5.4 with critical bug patched. I still haven't got the time to upgrade them to latest version. Will be glad to hear from those who have the 'cluster upgrade experience'.
& for that - if you contact your sales rep, professional services can help you out with the sizing (they have a process/method/some worksheets to calculate that as there's a lot to consider)
Yeah, for the record, support do resolve the sizing confusion! :)
Two thumbs up!
