The
Storage Performance Council I/O Benchmark |
|
Abstract: |
With
its announcement at CMG 2001, the Storage Performance Council
benchmark (SPC-1) became the first industry-standard benchmark
for testing I/O performance. During its development a key
SPC-1 requirement was to exhibit realistic behavior across
the entire spectrum of alternative cache implementations.
To provide a useful guide to the performance of real storage
systems under production conditions, benchmark performance
must depend, in a realistic way, upon such cache attributes
as size, staging algorithms, and sequential handling. The
SPC accomplished this by deploying a mix of different types
of I/O work, including "hierarchical reuse daemons".

Bio: |
Bruce
McNutt is a senior scientist/engineer working in the Storage
Systems Group of International Business Machines Corporation.
He has specialized in disk storage performance since joining
IBM in 1983. Among the many papers which he has presented
to the annual conference of the Computer Measurement Group,
as an active participant for more than fifteen years, are
two that received CMG "best paper" awards. His
recently published book, The Fractal Structure of Data Reference:
Applications to the Memory Hierarchy brings together two
threads which have run through his work: the hierarchical
reuse model of data reference, first introduced in 1991,
and the multiple-workload approach to cache planning, first
introduced in 1987.
