New hIOmon
Metrics Reveal Actual Impact of File Fragmentation |

|
BOULDER,
Colorado — September 19, 2006 — 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 that help bring to light the actual performance impact of
fragmented files upon file I/O operation activity. These metrics include the
number of
"split I/O"
operations (i.e., multiple I/O operations performed at the physical
device level within the operating system to satisfy a single file
I/O operation) observed for an individual file as well as the actual
percentage of "fragmented file I/O activity" (for both read and write I/O
operations) for a specific file. In addition, hIOmon can provide
summarized
"fragmented file I/O" metrics upon a device or even process/application basis. "The performance impact of fragmented files has long been a concern amongst computer users," said Tom West, President of hyperI/O LLC. "With Version 3.5, hIOmon users can now for the first time efficiently collect an essential set of summarized "fragmented file I/O" metrics that reflect how their particular applications and associated files are actually being affected by file fragmentation. And unlike benchmarking programs, hIOmon users can moreover collect these new file I/O performance metrics using their very own applications and files as they normally do within production environments — and without any file, application, or operating system changes". The new hIOmon "Fragmented File I/O Metrics" support can help users easily and quickly determine those specific files (and associated applications) that are suffering from “file fragmentation” based upon actual file I/O operation activity. Similarly, these new metrics provide empirical numbers that can help substantiate, for example, the impact of file fragmentation upon the file I/O performance of specific devices and processes/applications. The hIOmon "Fragmented File I/O Metrics" are based upon the "Physical Device Extended Metrics" support featured in hIOmon Version 3.5. Together with the "System File Cache" metrics already provided by hIOmon, the "Physical Device Extended Metrics" enable users to get a clearer, firsthand picture as to the exact extent to which their particular files of interest actually incur disk I/O operations and the related performance impact. 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 I/O trace and
summary/aggregate 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/device/process "Top Ten" list sorts and more. hIOmon
