Should I create Index Server group to include both Mailbox and Journal EV server or configured as ungroup? If configured both EV server into same Index Server group, I would need to include all Vault Store (VS-mailbox and VS-journal). I thought we should keep Journal and Mailbox archiving separately.
Solved! Go to Solution.
Do you run Discovery Accelerator at all and if you do do you *just* use the Journal archives or do you search user archives too?
Also have you rolled out anything like Vault Cache and Virtual Vault as well?
I forogot to add about Discovery Accelerator. Yes, we will be installing Discovery Accelerator. I think we want Discovery Accelerator to search user archives as well because we will be importing bunch of user PST files.
I have been testing the Enterprise Vault in the test environment. We have not deployed in the production environment yet, so this will be a new setup.
Yes, We would like to rolled out Vault Cache and Virtual Vault as well.
My personal opinion is that Index Server Groups are for HUUUUUGE deployments.. and therefore you're not likely to benefit from them.
(Also in the technotes, and help, for Index Server Groups it suggests NOT mixing journal indexes and mailbox/user indexes in the same index server groups -- therefore you're EV footprint is going to grow a fair amount)
Thank you all for the information, I will not use Index Server Group.
I have a few more questions:
We have 4 Exchange Servers with DAG. There are 16 Databases. All Exchange servers have at least 3-4 active databases.
2/ Yes you can.
Separated out is also good.. I mean it'll give you 'best' performance provided their on different physical disks.
3/ Different server.
For question one, i think if you were to have one journal mailbox for the entire exchange environment, it would require extra CAL's for Premium Journaling, as opposed to having a journal mailbox per exchange server, but i could be wrong on that
Premium Journaling require having Enterprise CAL. We do have enterprise CAL for 5,000+. We bought enterprise CAL because of Exchange 2010 archiving feature. Now we will be using Enterprise Vault, so I don’t see any reason to continue buying enterprise CAL for additional mailboxes in the future. We would save costs with standard CAL. I'll have to look more into Premium journaling if it is any better than using a standard journaling and what it will give us.
For Q1 I would personally look at four Journal mailboxes (one per server) this allows for growth but it also means you can have a seperate EV task per Journal Mailbox - which equates to seperate tasks per Exchange server allowing you to tweak performance of each task (each task would also have its own share of proccesses and resources) and monitor the archiving rates better coming from each exchange server if you also have an archive for each JM.
Incidentally I believe Premium Journaling allows you to be more granular in which mailboxes get which Journaling (so if you set a 7 year and 10 year retention Journaling you can manage per groups of uses as opposed to just pointing a DB at one and all users in the DB getting the same Journaling).
I will go with single journal mailbox to make it simple. Should I enable circular logging for the Journal mailbox? EV basically archived every mail it comes in so the logging will become no use and it will increase as it filled up the disk space.
