Zimbra on proxmox?

Postby iibarguren » Thu Apr 22, 2021 9:00 am

Hi,
we have a physical server with Ubuntu 14 and we have a huge problem after apt update and apt upgrade... some packages weren't installed and we didn't realize so we spent some hours without mail server.
We actually have a cluster of proxmox server and we are thinking maybe to buy a new server, add it to the proxmox cluster and use it exclusively for Zimbra (with HA and backups)
Is it good idea? Is it a good practice to virtualize Zimbra?

In my experience, these days it is rare to find a Zimbra installation that is not virtualized.

Hi,
We run Zimbra in Proxmox from several years, aprox 200 users.
The host machine is manly dedicated to Zimbra, with local disks in ZFS 10. Running in Centos.
Have online replication, do not have HA.

Works ok!

Several hundreds users on several Zimbra servers (multi-server platform) on Proxmox for years.
Primary volumes on Ceph-SSD (hyperconverged servers).
Secondary volumes on NFS.
