  • Page 100: Redundant Features

    IOs are moved between the controllers without any user intervention. A.4.2 Redundant Data Paths Dual data paths can be connected to the HBA from the Galaxy 16i RAID Subsystem. If one data path should fail the data can be transmitted through the alternative data path. Full host side redundancy can be achieved if two host channels are connected to two separate HBAs and then to the Host computer.

    A.5.4 Hot-Swapping of Drives A failed drive in the Galaxy 16i subsystem can be exchanged without turning off the system or interrupting the smooth operation of the system. Once the failed drive is replaced the data will be rebuilt in the background.
