Question - Is It Recommended To Create The Sap Maxdb Volumes On Raw Devices Or Files?
Answer -
The volumes of the type "File" and of the type "Raw" can be defined on UNIX.
A raw device is a hard disk or its any part which is not managed by the operating system. Data volumes of the type "raw device" can be configured for databases on UNIX.
Since the administrative effort which is required for file systems does not apply and so the access to raw devices is generally faster.
As the operating system does not have to check the consistency of the file system on raw devices, so it can usually boot faster.
Because of the above mentioned advantages, it is recommended to use raw devices on UNIX platforms. However, volumes of the type "File" on UNIX are also supported.
Volumes of the type "File" are the recommended standard in LINUX.
