SSD Cache Performance Kit (which operates with upto 4x customized 32GB
Intel SSDs) includes
software that identifies frequently (hot) read data blocks and optimizes
subsequent "reads" by moving "hot" data directly into the
SSD cache for lower latencies and higher system performance.

technology - which they leverage in their
MaxIQ SSD product - I
learned that the underlying technology was originally developed by
(surprise! surprise!) - Microsoft.
our datacenter team came up with some innovative ideas around using solid state
devices as read caching devices, we determined it made good sense to license
these advances to Adaptec because Microsoft itself doesn't sell these types of
products," said David Kaefer, GM of Intellectual Property Licensing at
Microsoft. "By collaborating through licensing, Adaptec customers benefit
from a product that delivers impressive performance and cost savings over
alternatives in the market."
Editor's comments:- the
whole hard disk array acceleration market will cease to exist in a handful of
years for reasons explained
the Microsofties realized it would be better to let someone else run with it -
rather than make users suffer the traditional 5 years waiting for it to
work properly - by which time it would be obsolete anyway.
