Implementing the IBM Storwize V7000

Chapter 12. IBM Tivoli Storage Productivity Center 483

򐂰 Comprehensive reporting: Tivoli Storage Productivity Center for Disk Midrange Edition

offers detailed metrics that include performance data for storage subsystems, controllers,

cache, I/O, arrays, disk groups, and ports. These performance statistics can be stored in

database tables for later use, so that storage administrators can track and measure

service levels.

򐂰 Easy Tier: Tivoli Storage Productivity Center for Disk Midrange Edition also provides

information about Easy Tier to monitor automatic migration of data assets to

high-performance disk tiers (such as solid-state drives (SSDs)).

򐂰 Advanced management: Tivoli Storage Productivity Center Standard Edition offers

performance metrics-based recommendations for provisioning, including SAN planning

(and DR planning with Tivoli Storage Productivity Center for Replication). The new

Disk

Magic

model of Tivoli Storage Productivity Center helps identify “hot spots”, improving

storage optimization for IBM Storwize V7000.

12.2 Tivoli Storage Productivity Center architecture

The IBM Tivoli Storage Productivity Center consists of the following key components:

򐂰 Data Server

򐂰 Device Server

򐂰 IBM Tivoli Integrated Portal

򐂰 Tivoli Storage Productivity Center for Replication

򐂰 IBM DB2 Database

򐂰 Agents

򐂰 Interfaces

12.2.1 Data Server

This component is the control point for product scheduling functions, configuration, event

information, reporting, and graphical user interface (GUI) support. It coordinates

communication with and data collection from agents that scan file systems and databases to

gather storage demographics and populate the database with results. Automated actions can

be defined to perform file system extension, data deletion, backup or archiving, or event

reporting when defined thresholds are encountered. The Data Server is the primary contact

point for GUI user interface functions. It also includes functions that schedule data collection

and discovery for the Device Server.

12.2.2 Device Server

This component discovers, gathers information from, analyzes performance of, and controls

storage subsystems and SAN fabrics. It coordinates communication with and data collection

from agents that scan SAN fabrics and storage devices.
