Configuring the EVM Network

Available Storage Systems

To compile a list of available resources, EVM queries every StorageWorks HSG- and HSV-based storage system in the SAN during startup and again at each periodic storage refresh. The more storage systems involved, the longer the refresh takes to complete.

To make this process more efficient, EVM lets users selectively filter out those storage systems not needed for EVM jobs. When storage systems are made unavailable to EVM, the startup and storage refresh complete more quickly.

To deselect storage systems:

1.Browse to the EVM GUI.

2.From the Resources page, click the Configuration tab.

3.From the EVM Configuration display, select the Available Storage tab.

4.In the Storage Systems section, click (uncheck) the storage systems you want to deselect.

5.Click Update to perform the deselection.

Storage System Refresh Interval

Successful EVM job execution depends on EVM having up-to-date storage information; periodic refreshes are critical. The following are factors to be considered in establishing the refresh rate:

If the storage configuration changes (for example, through the creation of a new unit or the deletion of an existing unit), EVM will not know about the change until a storage refresh occurs. Meanwhile, EVM jobs may fail as a result of using old storage information.

Refreshes are resource-intensive operations and, in extreme cases, can take as long as five minutes per storage system to complete. So, choosing an appropriate value for the refresh rate—one that balances performance with the need for current information—is an important part of managing an EVM network.

In stable environments where the storage configuration does not change frequently, a longer refresh period ensures better performance. In environments where storage changes frequently, a shorter refresh interval may be required.

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.
