Re: The only reason the S/390 is not doing GANGBUSTERs is MIPs based pricing by the S/390 Software Industry. Add Oracle to that list. The site is down now for maintenance, but go to www.oracle.com, then the Oracle store, and check the prices for X86, risc, and mainframe licenses. (as best as I can recall from memory, and I don't buy for mainframes so I don't pay that much attention to the pricing - if someone has a better recollection, please post) Equivalent are 10 600MHZ Xeons, 10 400MHZ SPARCs, and 1 mainframe mip. So the license fee for a 100 mip mainframe would be the same as for a cluster of 250 quad processor Xeon servers. (30 MHZ from an X86 is called a unit - a RISC MHZ is considered to be as good as 1.5 X86 MHZ and each mainframe mip is rated at 200 units) So Oracle thinks a small IBM S/390 is equal to 1,000 Xeons!

TWY, >If S/390 SW was priced like NT SW, the S/390 would be HANDS DOWN the cheapest and cheapest to run and FAR more manageable and reliable. I don't know about that anymore. Last I looked, 16 way S390s were in the millions of dollars, guessing about 4, with an appropriate amount of memory, channels, etc. If you remember the new IBM record setting tpm-c system we were kicking around this week, for 14 million, less than one fifth of that is for the server hardware (about $2.4 million). The rest, or about $12 million, went for storage hardware, client hardware, server and client software, and connectivity (hubs, etc.). The cost per CPU in the mainframe is 4,000,000 / 16 = $250,000. In the Xeon cluster: 2,400,000 / 128 = $18,750. You can't tell me that the S390 processors are THAT much more powerful than the Xeons!?! Of course, when I say cost per CPU, I'm simplifying and declaring all the hardware in the server as "CPU." That includes server memory, SCSI RAID adapters, etc. Just a way of trying to do an apples to apples comparison and keep it simple. The pricing for the IBM/128 way Xeon machine comes from: tpc.org Click on Executive Summary. Also check out the very nice block diagram! Tony
