I am long-time lurker. Soon I will have some decent hardware to run Network Edition. I was thinking of putting this on VMWare ESX. However, I am leary of doing so as the last time I didn't that Zimbra would consistently crash. At the time I was told this was due to the fact that Zimbra makes a tremendous amount of disk writes and that the disk sub-system was my problem. I had a Compaq G0 380 with 4 GB of RAM and 4 18GB SCSI disks configured in a RAID 5. From there I put ESX on it and then created my Zimbra guest. Is there a best practice out there using Zimbra with ESX? If so, what is the recommendation? Any input would be most appreciative.
