EVM Support for Volume Groups and HP Tru64 UNIX AdvFS Domains

•All physical volumes must be located on HSG or HSV storage.

For EVM to replicate a volume group, all physical volumes that comprise the volume group must be located on HSG or HSV storage. This HSG or HSV storage must be visible to EVM through the Management Appliance.

•Replicated volume groups cannot be mounted on the same host as the source.

Copying an entire volume group results in a new group that has the same volume group name as the source. No two volume groups can have the same name on the same host.

•Volume group names must be unique across all EVM host agents.

A common EVM configuration involves the allocation of a single EVM host agent computer as a backup server, which is used to mount and backup the replicated volume groups from multiple source hosts. Such configurations are supported, but if more than one replicated volume group is to be presented to the backup server at the same time, the source volume groups that the copies are created from must have unique names.

NOTE: This is not the case for HP Tru64 UNIX, where duplicates are renamed as needed.

•Any volume group Journaled File System (JFS) log file name must be unique across all 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.
