Glossary

BCV

Business Continuance Volume. A generic term for a virtual disk that is created from a standard production volume. A BCV can subsequently be used in production tasks such as backups, application migration, data mining, and testing. A key feature of a BCV is that it can be accessed while the production volume remains online for normal I/O. The term BCV does not imply the use of any specific technology.

CLI commands

The set of commands supported by StorageWorks HSG Array Controller Software. For example, the command SHOW DISKS displays a list of disks attached to the controller.

CLI

Command Line Interpreter or Interface. In StorageWorks, a text-oriented command line interface that enables configuration and monitoring of an HSG-based storage system by manually issuing commands to the array controller.

client

A computer or program that requests a service of another computer in a client-server system.

clone

In StorageWorks, an HSG controller-based method of creating a physical copy of a virtual disk. A duplicate member is created and members of the mirrorset are normalized to ensure that the data is identical on each member. During creation and normalization, the original remains online. Normalization of members is not instantaneous, but depends on factors such as disk size and I/O activity. Virtual disks created by the clone method are often used for tasks such as backups and application testing. The clone method cannot be used with RAID 3/5 units.

container

In StorageWorks, a logical volume identifier that the HSG controller uses to represent disks in a storage set. For example, the container identifier M3 could represent a RAID 1 two-disk mirrorset.

daemon

Diagnostic and Execution Monitor. Pronounced “demon.” A program usually associated with a UNIX system that performs a utility (housekeeping or maintenance) function without being requested or even known of by the user.

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.
