I had a question that hopefully you can answer. We are migrating from Exchange 2007 to Exchange 2016 (with a 2013 hop) and we are trying to properly configure the sizing on the server.
These new server for exchange 2016 will be on a ESXi/SAN environment.
Our current setup is:
500MB~ Average mailbox size for 450 mailboxes
100~ messages send/receive on each mailbox
8 Databases totaling only 480GB about 60GB each
3 servers. 2 mailbox, 1 cas.
Same as above except we will have a DAG protecting 4 databases.
Our PS team came back with needing almost 15TB of storage per server, 2 new servers. This seems excessive and something we do not currently have available on our SAN.
If you need any info please ask. Thanks.
