IBM Introduces New Volume Management Technology on Linux
IBM Wednesday announced a volume management solution for Linux that is designed to streamline and enhance enterprises' storage management capabilities.
Big Blue is billing Enterprise Volume Management System (EVMS) v1.0.0 as a state-of-the-art, easy-to-use volume manager that has unparalleled flexibility and expandability.IBM Wednesday announced a volume management solution for Linux that is designed to streamline and enhance enterprises' storage management capabilities.
A volume manager provides a virtual view of local and remote storage that can be used to combine or divide physical storage in a variety of ways, such as combining several physical disks to appear as one large disk.
Since operating systems manage storage and file volumes on servers by compressing them, controlling and balancing access, EVMS was designed to enable Linux to manage more content, files and users, and larger servers and simultaneously and more easily. With EVMS, Linux can support enterprise-level business applications customers need. It also allows users to access data and manage volumes from virtually any operating system.
EVMS integrates disk, partition, and volume management into a single, enterprise-level design and implementation, bringing industrial strength features found in proprietary volume managers to Linux.
"EVMS technology is a quantum leap forward in readying Linux for the enterprise," said Daniel Frye, director, Linux Technology Center, IBM. "When adopted in the base, EVMS will make Linux volume management world-class."
EVMS also has a plug-in system that supports all Linux volume management capabilities and allows volume managers found in other operating systems and other proprietary technologies to be emulated.
EVMS v1.0.0 supports multiple disk partitioning schemes, mirroring (RAID 1), striping with and without parity (RAID 0, 4, 5), drive linking, bad block relocation, and volume groups. Its modular, plug-in nature makes it scalable.
EVMS spawned from collaboration among developers in the Linux open community and the IBM Linux Technology Center (LTC). It is 100 percent open source and licensed under the GPL.
Several Linux distributors, including SuSe Linux and Turbolinux, are currently evaluating EVMS for bundling in upcoming releases.
The EVMS project is located on SourceForge at http://www.sf.net/projects/evms. The community there has had been involved with EVMS since its inception in January 2001.
