Hi,
I'm going to virtualize our mail server which is and will be a Linux VM with cyrus IMAP and postfix.
Actually the mailstore is about 1.6TB with a 2GB day growth.
The Virtual Machine will have a 1TB mailstore on a SAS aggregate of our Netapp Storage and a 5TB mailstore for archiving purposes residing on SATA aggregate on the same Netapp and the storage is connected to VSphere via NFS and iSCSI.
I think that there are only three possible storage setups:
1- Linux VM system disks on VMWare Datastore and mailstore via direct linux iscsi initiator
2- Linux VM system disks on VMWare Datastore and mailstore on linux LVM of 2TB VMWare vmdk disks
3- Linux VM system disks on VMWare Datastore and mailstore on two VMWare RDMs
I think that the best setup is the RDMs one but the second one should be more flexible in future expansions.
What do you think?
What are the pro and cons of theese setups in your experience?
Thanks
Giuseppe
