I understand all shops are different and 'it depends' applies...but we are curious as to the ratio of IFLs to Linux guest in other shops. Are there any shops out there running zLinux guests in production under z/VM with two or less IFLs besides us? We have four production Linux guests and twenty one test Linux guests supported by two IFLs on a z9BC.
