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
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
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:
IBM Tivoli Integrated Portal
Tivoli Storage Productivity Center for Replication
IBM DB2 Database
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.
