Use cases for Veritas InfoScale products
Veritas InfoScale Storage Foundation and High Availability (SFHA) Solutions product components and features can be used individually and in concert to improve performance, resilience and ease of management for your storage and applications. This guide documents key use cases for the management features of SFHA Solutions products.
Note:
The commands used for the Red Hat Enterprise Linux (RHEL) operating system in this document also apply to supported RHEL-compatible distributions.
Table: Key use cases for SFHA Solutions products
Use case | Veritas InfoScale feature |
|---|---|
Improve database performance using SFHA Solutions database accelerators to enable your database to achieve the speed of raw disk while retaining the management features and convenience of a file system. See About Arctera InfoScale™ product components database accelerators. | Concurrent I/O See About Concurrent I/O. Veritas Extension for Oracle Disk Manager Veritas Extension for Cached Oracle Disk Manager Note: For ODM amd Cached ODM information, see Storage Foundation: Storage and Availability Managment for Oracle Databases. |
Protect your data using SFHA Solutions Flashsnap, Storage Checkpoints, and NetBackup point-in-time copy methods to back up and recover your data. See Storage Foundation and High Availability Solutions backup and recovery methods. | FlashSnap See Preserving multiple point-in-time copies. See Backing up on an off-host cluster file system.
