Are you both a Z & V user?
Are you using both Zimbra & VMware in your organization?
If so, let us know by contacting vmware[~at~]zimbra.com We'd like to take a quick survey of deployments, and will be engaging in further communication on an individual basis, to examine areas were we can improve service and performance of both platforms (ie Zimbra running on VMware).
Yes you can participate even if using Zimbra Open Source or VMware free server.
Some helpful things to include in your first email to vmware@:
-Is your Zimbra instance running on a VMware deployment, or are you just using VMware elsewhere in your organization? (Have you given thought to virtualizing Zimbra at some point?)
-Zimbra Hardware setup; both physical (and virtual if it applies) server specs, cpu, mem, storage, net, etc?
-How many users?
-Are you a Network Edition customer of Zimbra? Direct or Partner (on-prem or HSP)?
-Are you a customer of VMware? Direct or Channel? (A provider datacenter setup, on-prem, or both.)
-VMware products used?
-In addition to VMware, are you using other virtualization solutions from another provider for x reason?
-Besides your Zimbra installation what's your ratio of virtual machines to physical.
-What is most likely your weakest link? ie: CPU, Disk, etc.
