Storage groups and Stores

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance



I have finally installed a exchange 2003 server in our exchange 5.5 site.
We have 2 exchange 5.5 servers, one in Belgium and one in UK. We have
installed the first exchange 2003 into the UK site.

Our next design issue is how many stores and storage groups we should use.
We have in total about 550 mailboxes, 300 in uk, 200 in bel and about 10 in
Netherlands, 20 in Germany and 20 in Ireland. The ireland and Germany
mailboxes are kept in the UK exchange 5.5 server and Netherlands on the Belg
exch 5.5 server.

Belgium and UK have their own software and backup schedules for their
mailboxes. We are not sure yet if we are going to migrate all mailboxes to
one exchange 2003 server or a seperate exchange 2003 boxfor uk and Bel. But
at the moment will be using one exch 2003 box in UK.

We are not bothered about back and restore strategies such quick to restore
seperate stores, what we want is good performance. SO from above can anyone
suggest what storage groups and stores we should use.

We are thinking of 1 one storage group and a seperate store for each country
even though some countries have about 20 users. All users in all countries
should have the same mailbox limits. We may have a different storage group
for Belgium, but would having more than one storage group affect
performance. Would several stores in one storage group affect performance.

Another key question is can we create more stores and storage group later
and move mailboxes between stores within a storage group and stores in
another storage group.

Apologies for too much information but I want to make the right decision
