Release of hIOmon Supports System File Cache Metrics |

BOULDER, Colorado — June 1, 2005 — hyperI/O LLC, the file I/O performance monitoring expert, announced today that its industry-leading hIOmon™ File I/O Performance Monitor now enables users to collect, display, and export a variety of enhanced metrics associated with the use of the system file cache. These metrics include both ‘hit’ and ‘miss’ counts and percentages along with the respective amount of data transferred. In addition, hIOmon™ can provide these summarized system cache metrics upon a specific file, device or even process/application basis. "Use
of the system file cache can greatly enhance file I/O operation performance,”
said Tom West, President of hyperI/O LLC. “With Version 3.4, hIOmon™ users can now for the first time efficiently
collect an essential set of summarized file I/O performance metrics that
reflect how their particular applications and associated files are actually
making use of the system file cache. And unlike benchmarking programs, hIOmon™ users can moreover collect
these key file system cache metrics using their very own applications as they
normally do within
production environments." The new
hIOmon™ 'System File Cache Metrics' support can help users easily and quickly
determine which specific files (and associated applications) are "cache-friendly" as well as those whose overall I/O operation performance is
effectively contingent upon the capabilities and particular utilization of the
underlying storage subsystem and infrastructure.
Similarly, these file cache metrics provide actual, empirical
numbers that can help substantiate, for example, the impact of additional
system memory upon the file I/O performance of specific files, devices, or
processes/applications. The hIOmon™ Version 3.4 also includes support for new metrics that reflect the amount of data transferred by random and sequential file accesses. In addition to random and sequential access file I/O operation counts and percentages, hIOmon™ users can now obtain the associated overall amounts of data transferred by random and sequential access file I/O operations respectively. Moreover, these random/sequential access metrics extend to the system file cache metrics as well. hIOmon™ Benefits hIOmon™
is a software package that provides a variety of significant benefits, including
the ability to better diagnose and understand storage access performance
problems, to verify and ensure that required levels of performance
(Quality-of-Service) are being met at the specific file/process level, to evaluate emerging storage technologies
(e.g., iSCSI, SATA, etc.) and proposed improvements to the performance of computer systems, and to help
reduce storage management costs.
Especially with its included support for Windows® Management
Instrumentation (WMI), end-users, integrators and Independent
Software Vendors alike find it easy to interface with hIOmon™.
‘Out-of-the-box’ features also include a Java™-based GUI, an Internet
Explorer GUI in addition to CLI
support, alert capabilities with System Event Log support, both detailed and
summary metrics upon an individual, specific file basis together with both real-time and replay
display modes, along with support for both the Windows® Performance and System
Monitors and several CSV-file export capabilities.
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/process 'Top Ten' list sorts and more. hIOmon™
