The Low End and High End MIPS/KVA are simply the ratios of the smallest and largest figures, respectively, for the series. It's possible to configure a skinny machine with high MIPS, getting more efficiency, or a fat machine with a slow engine, getting less, but these numbers seemed as good a way as any to sketch out the range. For the record, the Multiprise 3000, when fully configured, includes disk storage and that accounts for its poor high end power efficiency based on our crude calculations; none of the other machines in this table accept internal disks. The HP server at the bottom of the table is typical of today's four-way X86 midrange boxes and is configured with dual power supplies, 16 GB of main memory and 1.2 TB of internal disk. The MIPS power ratings are based on 6 to 10 clock cycles per equivalent mainframe instruction.
