Prognosis Disk Manager
Prognosis Disk Manager is a member of the Prognosis for HP NonStop systems management suite. By automatically monitoring your NonStop network at disk, subvolume, and file levels, Disk Manager maximizes the performance of your disk resources and improves overall system availability.

Inefficient use of disk resources affects system performance, wastes time, and ultimately costs you money. To optimize the effectiveness of these critical resources you need to be notified
automatically when disk-related problems arise and you need
the visibility to instantly pinpoint the cause. You also need the
ability to take corrective action before your business is impacted. Prognosis easily addresses these challenges and more.
Prognosis Disk Manager provides the most comprehensive
range of real-time disk-related statistics available. It helps avoid costly disk and application downtime caused by full disks or files. Prognosis also helps reduce storage costs by optimizing capacity and utilization.

With immediate access to I/O rates, response times, cache usage, and hundreds of other statistics, Prognosis identifies potential bottlenecks. It alerts you to problems such as files or disks nearing capacity, and incorrectly configured cache.
You can easily define thresholds to alert when exception conditions occur. For example, Prognosis can notify you when volumes become fragmented and when files are unable to allocate the next extent. You can also understand the usage of disk resources by NonStop and OSS applications.
Using sophisticated filtering and data reduction techniques, Prognosis minimizes data collection overhead. It gathers only the data that you specify - giving you maximum information with minimum resources.
You are able to specify which files and disks are monitored and which Measure data or SMF virtual disk information is collected. Prognosis can also monitor files for space data only, eliminating costly Measure overheads.

The information you need when you need it most. Graphical displays with intuitive navigation provide immediate access to real-time disk-related metrics. Volumes, subvolumes and files are just some of the components that can be tracked and managed in terms of usage, capacity, response times, growth rates, and other key efficiency indicators.

Planning and operational reporting. Using its highly efficient, integrated database, Prognosis captures key disk-related metrics. Collected information is automatically consolidated, providing HTML published reports such as disks by utilization, disks and subvolumes by space used, files by usage rate. |

Prognosis Disk Manager is easily extended through its seamless integration with additional
Prognosis products.
For example, you can instantly add functionality to provide advanced automation, notification via email, pager or mobile/cellular phone, integration with enterprise management frameworks, and so on.
Prognosis is the solution you need to optimize disk performance and utilization in your HP NonStop environment.
