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). A few recent posts mentioning mainframes
and TPC benchmarks:

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.
