I am about to order a new DELL server 2.4Ghz E5620 Xeon CPU that comes with 12GB of RAM and with a couple of SAS HDs ( I am going to add 4 more 600GB SAS HDs).
There won't bet SQL server running on this box, but going to run EXCHANGE 2010 with about 20 mailboxes w/ a total store size of 60GB and expect that to grow to probably 120GB - 200GB in the next 5 years. Other than Exchange, there are 20 users who use Office Apps (WORD/EXCEL/ACCESS).
How much memory would be adequate? I like to hear from people who installed SBS2011 on a new server box. This DELL R710 rack server can have up to 192 GB.
Thank you in advance.
