Product Overview

HP StorageWorks NAS Data Path Manager is an optional software product you
can purchase for the HP StorageWorks NAS 8000. It provides automatic path load
balancing and failover for NAS 8000 servers configured with multiple host bus
adapters (HBAs). The software allows you to customize your path settings, as
needed, to obtain optimum performance from your storage system. In addition,
Data Path Manager provides failover capability should all of the load balancing
(or optimal) paths fail.
HP NAS Data Path Manager provides:
Using dynamic load balancing, NAS Data Path Manager balances the flow of data
through multiple paths to a specific storage location using a least-used algorithm.
It detects multiple paths to each device, identified by a logical unit number (LUN),
and divides the data load among the designated preferred paths. See
Concepts
NAS Data Path Manager failover allows access to storage to continue
uninterrupted, in the event of a failure of all preferred paths, by using available
alternate paths.
