FSPM Software Description

The Oracle FS Path Manager (FSPM) software runs on the host system. For this operating system, multiple LUN paths are presented as multiple drives. With FSPM, every configured multi-pathed FSPM LUN is presented as a single drive to the operating system.

FSPM software integrates with the Microsoft Windows Multipath I/⁠O (MPIO) component.FSPM consists of a configuration service and an MPIO Device Specific Module (DSM) for Oracle FS System. This combination, along with the Microsoft MPIO component, allows Windows to detect and configure Oracle FS System storage devices and to manage the I/O paths to those devices.

Note: One host can access a maximum of 255 LUNs on each Oracle FS System. (The Oracle FS System supports more than 255 LUNs but Windows Servers do not support more than 255 LUNs.) The LUNs must be numbered from 0 to 254 because Windows does not recognize LUN number 255.

One host can access up to eight systems in any combination of Oracle FS System or Pillar Axiom systems.
