Configuring the EVM Network

Using EVM in a DRM Configuration

EVM is compatible with Data Replication Manager (DRM) configurations. However, management of a DRM environment may sometimes require that the Management Appliance be excluded from the configuration (zoned out). Whenever the Management Appliance is not part of the DRM configuration, the EVM server cannot access storage systems within the DRM configuration.

HSG Container Name Limitations

The EVM network software places some limitations on changing the name of a container. Keep these points in mind:

•Any HSG container name beginning with C! (capital “C” and an exclamation point) and ending with !C (such as C!12345!C) is reserved for EVM program use. The same restriction applies to any container name using this format with the letter “S” (such as S!12345!S).

CAUTION: Do not use “C!” or “S!” at the beginning of a container name, and do not use “!C” or “!S” at the end of one. Do not change the name of any container created by the EVM network that begins or ends with these sequences.

Changing the name of a container created by EVM may affect the ability of EVM to track that container. If a container name that uses the “C!...!C” or “S!...!S” format is changed, EVM will not properly recognize that container. Since EVM safety rules prohibit the EVM program from deleting anything that EVM storage did not create, the container will not function properly.

•Do not include the words Warning, Critical, or Error, in any form, in any container name. They are keywords used by EVM software for processing specific functions.

Fault Tolerance and Disaster Recovery

This section contains procedures for protecting the EVM network configuration in the event of a failure.

Using the Save Configuration Feature

EVM stores job files and critical configuration data on the Management Appliance. HP recommends saving this information to a host computer on a regular basis. Being able to reload the EVM configuration after a Management Appliance or EVM server failure can prevent re-creating EVM jobs and reinstalling the EVM host agents.

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.
