SCO Online Data Manager for OpenServer 6 provides software RAID Levels 0, 1, 5, 10 as well as on-line disk performance analysis. It includes a graphical Visual Administrator for exceptional ease-of-use, and supports online file system resizing, migration, and RAID level modifications. ODM is a cost-effective, enterprise-class storage management solution for high availability and online volume management.
ODM provides enterprise data management features such as online volume administration, online file system backup, improved synchronous write performance and further enhances file system I/O performance using enhanced I/O clustering. I/O clustering is a technique of grouping multiple I/O operations together for improved performance.
With ODM, large file access performance is comparable to that provided by raw disk. ODM also supports dynamic disk defragmentation and online file system resizing. With ODM, the system administrator can visually identify 'hot spots', or high activity areas on disks. These can then be moved closer together to reduce disk seek times or moved to other disks to increase performance. It also features hot-relocation, the ability of a system to automatically react to I/O failures and restore redundancy and data access, thereby saving valuable time and money.
