Yes we do have several DELL servers with DRAC. It is simply a KVM/IP. It will allow you to interact with the server even to the BIOS level. Thus, you can change your BIOS setting, fsck your server, or get into your server when it locks up, all remotely.
If you can have server with DRAC or some sort of KVM/IP to the server, then go for it. Some people offer console redirection. It's not the same at all. Console redirection works only on text. If won't do you any good if your windows server frezees up. DRAC or KVM/IP is a much more robust solution than mere console redirection. With DRAC you can also monitor the health of your computer (CPU temperature, fans status, etc). You can also use the DRAC to reboot from a OS image on the file on your computer, etc.
