A privately held Limited Liability Company founded in 1999 and
located in Boulder, Colorado, hyperI/O LLC offers product and service solutions
that are targeted to help address the fundamental performance gap between
computer systems and storage I/O. hyperI/O LLC has developed and currently
offers a premier, unique software solution called hIOmon™, the File I/O
Performance Monitor.
Users/applications armed with the extensive set of file I/O
performance metrics that only hIOmon™ provides can validate and continually
verify that those steps taken to maximize disk storage utilization and
performance are indeed of benefit. Such steps include identifying ‘hot
files’ and moving files around the storage hierarchy,
SAN,
NAS, etc. to improve
performance by making the best use of newly purchased hardware or without
spending IT dollars on new hardware. Use hIOmon™ to help identify those
files best suited for SSD,
RAM disk and other higher performance disk solutions. Substantiate the benefits
in terms of actual performance metrics specific to key files and the associated
applications. With its many features and capabilities (along with an extremely
efficient architecture), hIOmon™ answers the question: “How fast are
your files?”™ in terms of a variety of metrics, including response
time, I/O count, I/O rate, data transfer rate, system file cache 'hit' and
'miss' counts/percentages, queue depth and idle time, random/sequential access
detection plus real-time, metric-based file/device/process 'Top Ten' list sorts
and more.

the
Benefits of SAS (Serial Attached SCSI) for External Subsystems - article by
Adaptec
This introduction to Serial Attached SCSI gives you
an idea of the performance, compatibilities, applications and roadmap for this
new directly attached disk connection standard. With throughput capability
faster than 2Gbps Fibre-channel systems and faster than ultra320 SCSI - the new
SAS products not only provide an upward migration path for parallel SCSI
applications but also open the door to a new class of high performance high
reliability enterprise systems.
