I'm looking into a RIS solution for our enterprise and I'm trying to determine if I will need additonal hardware or if I can get by with what we have now. A brief description of our environment: We have 7 offices located in Florida with the exception of 1 in Atlanta, all of them are connected via MPLS. In our two largest offices we running a fiber connected SAN, but the other 5 offices all use local drives for each server. We are running one domain, but each office is on it's own subnet, with the 2 largest offices encompassing multiple subnets. What I'd like to do is ensure that each office is hosting it's own RIS images so there will be nothing being pulled across the WAN. I'd prefer to do this without adding any additonal servers if possible, but getting new drives, RAM, ect... is ok. Is this reasonable? Should I be installing RIS on one of our Domain Controllers, they have 2GB of RAM and dual 3.5ghz processors, in each office? I know RIS needs it's own partition, but what is a reasonable size for the partition, assuming I will not be using more than 3 or 4 images at each office, but leaving room for some growth? I'm curious as to the bandwidth that RIS takes up as well, is it reasonable to reimage a machine or two during the day assuming a 100mb LAN (We have GB backbones in several of the offices, but not GB to the desktop, and some of the older offices still only have 100MB backbones.)? I've found this site to be extremely helpful while I've been researching RIS, and I've spent some time working on creating an Unattended Installation DVD using the guide here. I'm beginning to build a test RIS box now, but I've got to turn in some budget numbers by the end of next week, and I want to do my best to have an accurate idea of what I'll need to implement RIS sometime next year. My guess is diskspace is all I'm really going to need, but I thought I would ask here. Thanks for all your help and for providing a wonderful resource.
