One of the main new features of IBM® Installation Toolkit for PowerLinux version 5.3 is the support for facilitating Linux installations, on top of multipath devices.
Multipath I/O Linux layers can be enabled on IBM PowerLinux servers with multiple physical paths to storage devices (through SANs or direct attached), where they can be used to increase storage path redundancy, as well as to enhance server performance though typical features, such as:
- Dynamic load balancing
- Traffic shaping
- Automatic path management
- Dynamic reconfiguration
With this new IBM Installation Toolkit feature, once you are done with the installation wizard, your Linux system will be able to leverage the the multipath I/O capabilities from your IBM PowerLinux server, without any extra configuration steps.
