Configuring the EVM Network

Refresh rate is also dependent on how busy the HSG and HSV element managers are. If, for example, the element manager is in the process of doing a resource-intensive function, it will be less responsive and EVM discovery will be slower.

By default, EVM refreshes the storage configuration information displayed by the GUI on a periodic interval equal to 5 minutes times the number of storage systems, or every 15 minutes, whichever is greater. For example, a configuration with 10 storage systems has a default refresh rate of every 50 minutes. This default value can be overridden through a user-defined, selectable refresh rate.

To establish a refresh rate manually, access the GUI Options page. From the EVM Configuration page, choose the Available Storage tab and locate the Refresh Rate section.

Detect Storage Properties

A manual refresh-on-demand allows a manual storage refresh to be performed at any time. This feature is available only from the EVM Resources page. To initiate the detect:

1.Right-click in any open area of the upper or lower pane and choose Refresh.

2.Right-click in any open area of the upper or lower left panes of the EVM Resources page to display the Redraw Resource Diagrams and Detect Storage Properties options.

Clicking Detect Storage Properties causes EVM to refresh storage system information without waiting for the next automatic refresh.

NOTE: Clicking Redraw Resource Diagrams causes EVM to refresh the EVM Resources page from cached information.

Element Manager Requirements

The EVM element manager provides access to the StorageWorks storage system and is the interface to the HSG or HSV SAN network. The required element manager for EVM is included in the Management Appliance with the OSM January 2002 Update.

To determine whether you already have the update, browse to the Management Appliance and navigate to the OSM Home Page. If you do have the OSM January 2002 Update, the title bar in the Content pane contains the designation “Open SAN Manager V1.0C.” If the title bar specifies any other version, you do not have the OSM January 2002 Update.

Enterprise Volume Manager Software specifications

HP Enterprise Volume Manager (EVM) Software is a robust solution designed to optimize storage management for enterprise environments. This innovative software addresses the complexities of managing data across diverse storage systems while enhancing performance, scalability, and efficiency.

One of the key features of HP EVM is its ability to centralize storage management. By providing a unified interface, it streamlines administrative tasks, enabling IT teams to manage storage resources from a single console. This centralization not only simplifies operations but also reduces the potential for human error, leading to more reliable data management.

Another significant feature is the software's powerful automation capabilities. HP EVM automates routine tasks such as data provisioning, monitoring, and reporting. This functionality empowers organizations to allocate resources efficiently, respond to changes in demand swiftly, and ensure optimal performance without extensive manual intervention. Automated alerting and reporting mechanisms provide visibility into storage utilization and performance metrics, allowing for proactive management of storage resources.

HP EVM also supports advanced storage technologies like thin provisioning and deduplication, which help maximize storage efficiency. Thin provisioning allows organizations to allocate storage on an as-needed basis, minimizing wastage and ensuring cost-effective utilization. Deduplication, on the other hand, reduces redundant data, freeing up valuable storage space and improving backup and recovery times.

Scalability is another hallmark of HP EVM. The software is designed to grow with an organization's needs, supporting a wide array of storage devices, from traditional disk systems to flash storage. This flexibility ensures that enterprises can adapt to evolving data demands and technological advancements without overhauling existing infrastructure.

Security features integrated into HP EVM are essential for protecting sensitive data. The software supports robust encryption protocols and access controls, ensuring that data remains secure during transitions and while stored across multiple locations. Compliance with industry regulations is facilitated through comprehensive logging and reporting features, enhancing an organization’s ability to maintain regulatory standards.

In conclusion, HP Enterprise Volume Manager Software is a pivotal tool for organizations seeking efficient and effective storage management. With its centralized management capabilities, automation features, support for advanced storage technologies, scalability, and strong security measures, HP EVM stands out as a vital asset that drives operational efficiency and data integrity in today's data-centric enterprises. Investing in HP EVM not only simplifies storage management but also empowers organizations to proactively meet their data challenges.
