BMR SRT for both x64 and x32 Windows clients

Hi

I'm sure this may have been asked before but I've trawled through manuals and still a little confused :o(

If I need to protect both x32 and x64 windows clients with NBU 7.6 BMR, do I need to create 2 x boot servers? I know I need 2 SRTs - one created with x32 architecture and 1 with x64 architecture, but I can't see if it is possible to create both SRT's on the same Windows boot server? Or is it a 1:1 relationship (a boot server can only host a single SRT). I also plan to use my windows master server as the boot server and this is a VMware vm - is that ok to do?

hope that makes sense.
