Overview
VxVM is a storage management subsystem that enables you to manage physical disks as logical devices.
Application programs and operating systems consider a VxVM volume as a physical disk where file systems, databases, and other entrusted data objects can be configured.
VxVM provides simple functions of managing online disks for the computation environment and storage area networks (SANs). It has the following advantages:
- Supports RAID.
- Provides functions that improve error tolerance and enable quick disk failure recovery.
- Provides an LV management layer to enable cross-disk management and remove physical restrictions of disk devices.
- Provides tools that improve performance and ensure data availability and integrity.
- Enables dynamic disk storage configuration when the system is active.
