NAS Data Path Manager

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:

■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. See Data Path

Concepts on page 12.

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.

NAS Data Path Manager

10 hp StorageWorks NAS Data Path Manager Installation and User’s Guide

Note: Data Path Failover and failover packages are different NAS 8000 features.

■Data Path Failover is the ability of your system to use alternate fibre-channel paths to

get information to your storage in case all of the preferred paths fail. Data Path

Failover can be installed and used on any NAS 8000 (version 1.6.0 or later) high

availability (HA) or non-HA system, with the correct firmware revision. Please

contact your HP Service Representative for firmware information or updates.

■Failover packages appear only on NAS 8000 systems with high availability (HA).

Using failover packages, your system can transfer control of data, per failover

package, to a different NAS 8000 server if one server fails. For more information

on failover packages, please see the NAS 8000 User’s Guide.

Graphical User Interface

Once NAS Data Path Manager is installed on a NAS 8000 server, additional items

will appear in Command View NAS, the NAS 8000 graphical user interface. This

allows the administrator to view and manage NAS Data Path Manager

functionality on the NAS 8000 using the same interface used to perform all other

storage management tasks.

System Requirements

NAS Data Path Manager has the following system requirements.

■HP StorageWorks NAS 8000 system, (hpNasOs) version 1.6.0 or later

■Fibre-channel storage devices

■Host bus adapters (HBAs) connected to your fibre-channel storage devices

■HBA firmware v3.90a7 or later

■VA710x, VA740x, VA741x, XP, EMA, and/or EVA storage arrays
