<p>Microsoft will release Cumulative Update 2 (CU2) for Exchange Server 2013 sometime this summer, the company said on Tuesday.</p><p>For the Enterprise edition, the update will increase the maximum number of supported databases per server from the current 50 to 100, according to a post on the Exchange blog by Ross Smith IV, principal program manager for Microsoft's Exchange Customer Experience team.</p><p>In developing Exchange 2013, Microsoft initially lowered the limit for supported databases from 100 to 50 to improve performance. The company is restoring the original 100-database limit with CU2 in response to user complaints, Smith said.</p><p>"Since the release of Exchange 2013, we've received an inordinate amount of feedback regarding the reduction in supported databases per-server. The driving response has been 'we currently deploy more than 50 databases per-server in Exchange 2010; with this change, this means we will need to deploy more servers, which increases our capital expenditures significantly,'" he wrote. "Rest assured, that is not the message we want with Exchange 2013. It is true that Exchange 2013 utilizes more CPU and memory than its predecessors -- this is due to the architecture changes we've made, as well as the changes we've made to reduce disk IO, so that you can deploy more mailboxes per disk. But we do not want to see architectures artificially limited by the supported databases per-server constraint."</p><p><a href="http://rcpmag.com/articles/2013/06/04/exchange-2013-cu2.aspx">Keep reading...</a></p>
