"Also is this software compatible with all Dell servers? " Most.  In the Compatibility section of the download page, it will list the servers that particular version will work on. "I guess this iso is bootable as I understand from txt file." Yes.  You will download and run the file, it will create a bootable ISO you can either save and burn yourself or burn directly to CD. On the T710, you can go to F10 and choose diagnostics from the system services boot options.
