About Veritas InfoScale product components database accelerators
The major concern in any environment is maintaining respectable performance or meeting performance service level agreements (SLAs). Veritas InfoScale product components improve the overall performance of database environments in a variety of ways.
Table: Veritas InfoScale product components database accelerators
Veritas InfoScale database accelerator | Supported databases | Use cases and considerations |
---|---|---|
Oracle Disk Manager (ODM) | Oracle |
|
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. |
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.
