more than one driver installed, which is active?

Server HP DL360e Gen8 with RHEL 6.5

Hello

This is a common question for me, I just want to know if it is working or it is dangerous.
When I get a new driver from the HP site, I just used to install it like that : rpm -ivh ******.rpm
In my case, I can see with the option -qa and -qi both versions of the same driver.

How can I find out which driver version is active now for that hardware?
Shall I uninstall first the older driver before installing the newest?

[root@123456 ~]# rpm -qa kmod-hpvsa
kmod-hpvsa-1.2.6-26.rhel6u3.x86_64
kmod-hpvsa-1.2.8-160.rhel6u5.x86_64
[root@123456 ~]# rpm -qi kmod-hpvsa
