About InfoScale product components database accelerators

The major concern in any environment is maintaining respectable performance or meeting performance service level agreements (SLAs). InfoScale product components improve the overall performance of database environments in a variety of ways.

Table: InfoScale product components database accelerators

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 Volume Manager (VxVM) 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.

Quick I/O (QIO)

Oracle

DB2

Sybase

To achieve raw device performance for databases run on VxFS file systems, use Quick I/O.

Cached Quick I/O (Cached QIO)

Oracle

DB2

Sybase

To further enhance database performance by leveraging large system memory to selectively buffer the frequently accessed data, use Cached QIO.

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 VxFS Concurrent I/O.

These database accelerator technologies enable database performance equal to raw disk partitions, but with the manageability benefits of a file system.

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