how much physical disk space Zimbara will use ?

[raj]

Hello Everyone:
Below example is to figure out how much capacity planning we need to do in terms of PHYSICAL SAPCE on disks

If we have 100 Emails of 1 MB Each

Splitting the size of each email for hypothetical example:
Aprox. 5 KB Header Text
Aprox. 500 KB Body Text
Aprox. 500 KB Attachment

So how much physical disk space Zimbra will use roughly, excluding logging and stuff

1) Aprox. 100 x 1 = 100MB or more to keep the mails in FILE STORE
2) Aprrx. Index Size ?]
3) Aprox. Mysql Size ?
4) Any other space requirements for Zimbra

If above example is not good enough then any other way we can do disk space capacity planning.
i.e.: For every 1 GB Of Physical Email File Store how much more space Zimbra will use roughly.

I just did a very rough calculation on my development build and came up with about 5% overhead each for the database and index. So expect to use about an extra 10% of disk on top of the message blob size.

If disk space is a concern, there's also an option you can set with zmvolume to compress message blobs stored on a given volume. This will allow you to use less disk space for the message store, at the expence of some extra CPU load.

Cool..10% is not an issue..Thanks

If anyone else has any other real-time data on production machine where users are storing lots of searches, tags and appointments how dose that affect the storage/disk usage.

Thanks

My settings rite now

[zimbra@pluto ~]$ zmvolume -dc
   Volume id: 1
        name: message1
        type: primaryMessage
        path: /opt/zimbra/store
  compressed: false

   Volume id: 3
        name: message2
        type: secondaryMessage
        path: /opt/zimbra/archive
  compressed: true               threshold: 4096 bytes

Will it be harmful in any way(speed or data integrity) for let say future backup/restore, user mail search etc.. if i compress the primaryMessage.
