Starting EVM and Controlling Access

This chapter provides information on starting and stopping the EVM server and EVM host agents, browsing to the EVM network, and controlling access to the EVM network. It discusses the following major topics:

Starting the EVM Service or Daemon on page 7–1

Establishing Password Control on page 7–4

Browsing to EVM on page 7–7

Starting the EVM Service or Daemon

Restarting the host computer automatically starts the EVM service for Windows operating systems or the EVM daemon for UNIX operating systems. Once started, the service or daemon for an EVM host agent can be manually stopped and restarted on a host computer, but the service for the EVM server cannot be stopped.

For UNIX computers, the EVM program and associated support scripts are installed with root execute permission only. To run EVM, root permissions are required.

Automatic Starting of the EVM Service or Daemon

During installation, the EVM server is installed as a Windows service. EVM host agents are installed as either a Windows service for Windows operating systems, or as a daemon for UNIX operating systems. The EVM service or daemon can be started during the installation, if desired. To manually activate this service or daemon following the EVM host agent installation, refer to the next section.

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.
