Veritas Quick I/O supports direct I/O and kernel asynchronous I/O and allows databases to access regular files on a VxFS file system as raw character devices.
The benefits of using Quick I/O are:
Improved performance and processing throughput by having Quick I/O files act as raw devices.
-
Ability to manage Quick I/O files as regular files, which simplifies administrative tasks such as allocating, moving, copying, resizing, and backing up containers.
