Differen approaches: more journal mailboxes, longer mailbox archiving?
Hi,
As you may have noticed, we're still working on possible archiving scenarios for out project. Now that we have more realistic numbers on # emails to journal, # of mailbox items to archive, SIS requirements, etc. we have come up with some options which we would like to validate.
Assumptions:
- Use as less as possible Exchange mailbox servers.
- Use as less as possible journal archiving servers (virtualized).
- Use as less as possible mailbox archiving servers.
- Keep the number of items in a Journal mailbox limited to 15.000-25.000 (in case the journal archiving is shut down for whatever reason).
Option:
1) Use a Journal mailbox for every mailbox store. We would start with around 20, and grow to around 35 journal mailboxes.
We know about additional load on the Exchange servers, but assume the Exchange server could be configured to allow for this additional archiving load from the Journal archiving processes.
Q1: Which parts of the Exchange (2007) is important to review? Store process (more memory), Network, IOPS, other areas? Would a separate Journal Mailbox server be an alternative?
2) Don't run mailbox archiving only after office hours, but also during the day (18-24 hours per day).
Q1: Is there any experience with this, and if so, what to look for?
Q2: Is there a reason not to do it?
Thanks in advance.
