separating index services and storage
hello. thanks for the time. we are upgrading from EV 9 to EV 10 and we want to separate the index from the storage services. we have 2000 users and I was reading if you have more than 4000 then thats when its worth separating and creating an index storage group. If we create one now ...it might not be as beneficial since the server wont be heavily taxed. we also have a separate server for DA and File Share.
the reason that the business wants to separate the index and storage is so that when a search is done is it not done against the index as well as the vault store? or do i have this incorrect? the problem is when legal does a search they get duplicate results and were told that separating this out will relieve that. And my thinking is that since the journal archive mailbox and user mailboxes is on the same vaultstore thats why they are getting duplicates? should we separate that out?
Does this need to be done during the change location wizard during the setup? or can i create an index server group after 10 is installed? Lastly is there any more information on SharePoint archiving besides what is given in the installation guide? any help would be appreciated. thanks.
