Software ove

rview

Smart Array Multipath software delivers dual path functionality, and supports failover capability for a

redundant HBA in a server with redundant cabling to an HP StorageWorks Modular Smart Array 500

Generation 2 storage system. This fault-tolerant tool enhances availability in clustering and DAS solutions

with up to two servers, managing up to 2 TB of stored data.

The software supports multiple I/O paths to the same logical volumes. When a path fails, the software

moves the logical drives from the failed path to the path of the redundant HBA in the same server.

Smart Array Multipath software works differently with Microsoft and Linux products, to provide speciﬁc

features t

hat are compatible with the operating system functionality.
