Description
===========
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:
Faster performance through dynamic load balancing over multiple
paths from the HBAs to the Storage controllers.
Automatic data path failover to an alternate path when a
preferred path fails.
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.
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.
