at hundreds of thousands blades in a megadatacenter and multiple megadatacenters spread around the world ... they claim that they can build their own for 1/3rd the price of brand name blades. they also have done quite a bit of research into reliability of different commodity components and buy in quantity for total cost of ownship. They also tend to have some leverage over vendors that sell into the megadatacenter server market. with the enormous reduction in cost of hardware that they've been able to achieve (if IBM has base price of $1815 for e5-2600 blade or approx. $3.44/BIPS ... and megadatacenter may be able to achieve 1/3rd that ... compared to $560,000/BIPS for z196) ... other costs start to play an increasing role. The megadatacenters have also pioneered much of the green datacenter efforts ... radically reducing power and cooling costs ... establishing power&cooling cost measures per unit of computing ... somewhat analogous to the TPC council ... total cost per transaction (gives results sorted by performance, price/performance and watts/performance).

One of the issues is they have done significant excess provisioning for "on-demand" requirements and so have pressured vendors for implementations that drastically cut power use when idle ... but able to instantaneously come up to full-speed. They've also openly published their findings ... hoping to encourage the component vendors to compete & improve their products. However, their findings have also tended to influence blade component selection and assembly by others. recent posts in this thread http://www.garlic.com/~lynn/2012l.html#16 X86 server http://www.garlic.com/~lynn/2012l.html#18 X86 server http://www.garlic.com/~lynn/2012l.html#19 X86 server http://www.garlic.com/~lynn/2012l.html#20 X86 server http://www.garlic.com/~lynn/2012l.html#25 X86 server -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
