What server management software should I download for T320?

Sorry for newbie question, I just got my first server for business use.

Power Edge T320 x 1 , no RAID , no Controller , 1 HDD , 1 OS , with 4-5 client (wireless connection + windows 7 / windows 8)

Right now, T320 running on Windows SBS 2011 essential OS.

It has Dell Openmanage System Administrator which can be run on Server only or using Windows Remote Desktop connection (Am I right?...)

If I wish to manage/monitor my server from client computer, Can I do it? Which Software can I use ? or any Windows SBS2011 Add-ins?

but I tried to search google + dell.com but the results return too many softwares.

I downloaded them but found out that they are not compatible ( ie. Open Manage Essential).

Any help would be appreciated.

Thank you
