Navigator 2 overview

Navigator 2 functions

12 Introduction


Navigator 2 overviewThe Hitachi Data Systems Navigator 2 empowers you to take advantage of the full power of your Hitachi storage systems. Using Navigator 2, you can configure and manage your storage assets from a local host and from a remote host across an Intranet or TCP/IP network to ensure maximum data reliability, network up-time, and system serviceability.

The role that the Navigator 2 management console plays is to provide views of feature settings on the storage system in addition to enabling you to configure and manage those features. The following section provides more detail about what features Navigator 2 provides to optimize your experience with the Hitachi Unified Storage system.

Navigator 2 featuresNavigator 2 provides the features detailed in the following sections.

Security features Account Authentication - Account authentication and audit logging

provide access control to management functions. Audit Logging - Records all system changes. SAN Security - SAN security software helps ensure security in open

systems storage area networking environments through restricted server access.

Monitoring features Performance Monitor - Performance monitoring software allows you

to see performance within the storage system.

Configuration management features LUN Manager - Software that manages volumes streamlines

configuration management processes by allowing you to define, configure, add, delete, expand, revise and reassign VOLs to specific paths without having to reboot your storage system.

Replication Software - Replication setup and management feature provides basic configuration and management of Hitachi ShadowImage products, Hitachi Copy-on-Write Snapshot software and Hitachi TrueCopy mirrored pairs.

System Maintenance - System maintenance feature allows online controller microcode updates and other system maintenance functions.

SNMP - Simple Network Management Protocol (SNMP) function agent support includes MIBs specific to Hitachi Data Systems and enables SNMP-based reporting on status and alerts for Hitachi storage systems.

Data migration features Modular Volume Migration Manager - Modular volume migration

software enables dynamic data migration.

Introduction 13


Cache Residency Manager - This feature allows you to "lock" and "unlock" data into a cache in real time for optimal access to your most frequently accessed data.

Capacity features Cache Partition Manager - This feature allows the application to

partition the cache for improved performance. RAID Group Expansion - Online RAID group expansion feature

enables dynamic addition of HDDs to a RAID group.

General features Point and click GUI - Point-and-click graphical interface with initial

set-up wizards that simplifies configuration, management, and visualization of Hitachi storage systems.

Real-time view of environment - An immediate view of available storage and current usage.

Deployment efficiency - Efficient deployment of storage resources to meet business and application needs, optimize storage productivity, and reduce the time required to configure storage systems and balance I/O workloads.

Access protection - Protection of access to information by restricting storage access at the port level, requiring case-sensitive password logins, and providing secure domains for application-specific data.

Data redundancy - Protection of the information itself by letting you configure data-redundancy and assign hot spares.

System management - functions for Hitachi storage systems, such as storage system status, event logging, email alert notifications, and statistics.

Major platform compatibility - Compatibility with Microsoft Windows, UNIX, and Linux environments.

Online help - Online help to enable easy access to information about use of features.

Command Line Interface - A full featured and scriptable command line interface. For more information, refer to the Hitachi Unified Storage Command Line Interface Reference Guide.

Navigator 2 benefitsNavigator 2 provides the following benefits: Simplification - Simplifies storage configuration and management for

the HUS family of storage systems. Access protection - Protects access to information by allowing secure

permission to assigned storage Performance enhancement - Enhances data access performance to

key applications and protects data availability of mission-critical information

14 Introduction


Optimization of data retrieval - Optimizes storage administrator productivity by reducing the time required to configure storage systems and balance I/O workloads

Enables integration - Facilitates integration of Hitachi storage systems with enterprise management products

Cost reduction - Reduces storage costs. Long-term planning enabler - Improves the organizations long-term

sustainable business strategy. Establishment of metrics - Identifies clear metrics with a full analysis

of the payback period and savings potential. Capacity provisioning - Provisions content storage capacity to

organizations and to post production end users.

Navigator 2 task flowThis section details the task flow associated with the Navigator 2 Management Console.1. You install and provision a Hitachi Unified Storage system2. You install Navigator 2.3. Using Navigator 2, you access data on your host systems.4. You store data in the HUS system.5. You create volumes and assign pieces of the stored data to volumes.6. You partition portions of the cache on the HUS and assign data to the

partitions.7. You set up Performance Monitor to view and monitor activity on the

Hitachi Unified Storage system.8. You set up SNMP Agent Function to generate traps when certain

thresholds have been exceeded.9. You set up the Audit Logging function to send logs to the syslog when

certain events occur.

Introduction 15


Figure 1-1 shows how Navigator 2 connects directly to the front-end controller of the HUS family storage system.

Figure 1-1: Navigator 2 task flow

The front-end controller communicates to the back-end controller of the storage system, which in turn, communicates with the Storage Area Network (SAN), often a Fibre Channel switch. Hosts or application servers contact the SAN to retrieve data from the storage system for use in applications, commonly databases and data processing programs.
