Linux
Fujitsu provides a device driver for Linux platforms supporting MPIO, utilizing Fujitsu’s multi-path driver, or
Linux DM driver.
IBM AIX
For the AIX platform, Fujitsu’s MPD is an interface to AIX’s native multi-pathing I/O capabilities. The
ETERNUS MPIO for AIX is an IBM Path Control Module (PCM) that utilizes AIX’s native multi pathing
capabilities, through the MPIO interface. ETERNUS systems utilizing this software may be accessed as an
MPIO device by AIX. This allows active/active asymmetric logical unit access via AIX.
ETERNUS MPIO for IBM AIX performs load-balancing over the usable paths to improve the access
