<p>Hello</p>
<p>We have a small office with 25 clients and 4 servers with a mssql db, domain controllers, exchange 03 and ms file server.<br>
Is it possible to migrate them to a two node cluster with drbd?<br>
We need HA on these roles but I do not know how will specific services like sql or exchange will react on live migration.<br>
Is there a possibility to get corruptions on sql or exchange db?<br>
Also is it recommended for a file server to be virtualized or a separate NAS will be better for that role?<br>
What about DCs?</p>
<p>Thank you in advance</p>
