Veritas InfoScale database accelerator	Supported databases	Use cases and considerations
Oracle Disk Manager (ODM)	Oracle	To improve Oracle performance and manage system bandwidth through an improved Application Programming Interface (API) that contains advanced kernel support for file I/O. To use Oracle Resilvering and turn off Veritas Volume Manager Dirty Region Logging (DRL) to increase performance, use ODM. To reduce the time required to restore consistency, freeing more I/O bandwidth for business-critical applications, use SmartSync recovery accelerator.
Cached Oracle Disk Manager (Cached OD M)	Oracle	To enable selected I/O to use caching to improve ODM I/O performance, use Cached ODM.
Concurrent I/O	DB2 Sybase	Concurrent I/O (CIO) is optimized for DB2 and Sybase environments To achieve improved performance for databases run on VxFS file systems without restrictions on increasing file size, use Veritas InfoScale Concurrent I/O.

Oracle

To enable selected I/O to use caching to improve ODM I/O performance, use Cached ODM.

Concurrent I/O

DB2

Sybase

Concurrent I/O (CIO) is optimized for DB2 and Sybase environments

To achieve improved performance for databases run on VxFS file systems without restrictions on increasing file size, use Veritas InfoScale Concurrent I/O.

These database accelerator technologies enable database performance equal to raw disk partitions, but with the manageability benefits of a file system. With the Dynamic Multi-pathing (DMP) feature of Storage Foundation, performance is maximized by load-balancing I/O activity across all available paths from server to array. DMP supports all major hardware RAID vendors, hence there is no need for third-party multi-pathing software, reducing the total cost of ownership.

Veritas InfoScale database accelerators enable you to manage performance for your database with more precision.
