Chapter 1. IBM TotalStorage Productivity
Center overview
IBM TotalStorage Productivity Center is software, part of the IBM TotalStorage open software
family, designed to provide a single point of control for managing both IBM and non-IBM
networked storage devices that implement the Storage Management Initiative Specification
(SMI-S), including the IBM TotalStorage SAN Volume Controller (SVC), IBM TotalStorage
Enterprise Storage Server (ESS), IBM TotalStorage Fibre Array Storage Technology
(FAStT), and IBM TotalStorage DS4000 series.

TotalStorage Productivity Center is a solution for customers with storage management
requirements, who want to reduce the complexities and costs of storage management,
including management of SAN-based storage, while consolidating control within a consistent
graphical user interface.

While the focus of this book is the IBM TotalStorage Productivity Center for Disk and IBM
TotalStorage Productivity Center for Replication components of the IBM TotalStorage
Productivity Center, this chapter provides an overview of the entire IBM TotalStorage Open
Software Family.

1.1 Introduction to IBM TotalStorage Productivity Center
The IBM TotalStorage Productivity Center consists of software components which enable
storage administrators to monitor, configure, and manage storage devices and subsystems
within a SAN environment.

The TotalStorage Productivity Center is based on the recent standard issued by the Storage
Networking Industry Association (SNIA). The standard addresses the interoperability of
storage hardware and software within a SAN.

1.1.1 Standards organizations and standards
Today, there are at least 10 organizations involved in creating standards for storage, storage
management, SAN management, and interoperability. Figure 1-1 shows the key
organizations involved in developing and promoting standards relating to storage, storage
management, and SAN management, and the relevant standards for which they are
responsible.

Figure 1-1 SAN management standards bodies

Key standards for Storage Management are:
Distributed Management Task Force (DMTF) Common Information Model (CIM)
Standards. This includes the CIM Device Model for Storage, which at the time of writing
was Version 2.7.2 for the CIM schema.
Storage Networking Industry Association (SNIA) Storage Management Initiative
Specification (SMI-S).

1.2 IBM TotalStorage Open Software family
The IBM TotalStorage Open Software Family, is designed to provide a full range of
capabilities, including storage infrastructure management, Hierarchical Storage Management
(HSM), archive management, and recovery management.

The On Demand storage environment is shown in Figure 1-2. The hardware infrastructure is
a complete range of IBM storage hardware and devices providing flexibility in choice of
service quality and cost structure. On top of the hardware infrastructure is the virtualization
layer. The storage virtualization is infrastructure software designed to pool storage assets,
enabling optimized use of storage assets across the enterprise and the ability to modify the
storage infrastructure with minimal or no disruption to application services. The next layer is
composed of storage infrastructure management to help enterprises understand and
proactively manage their storage infrastructure in the on demand world; hierarchical storage
management to help control growth; archive management to manage cost of storing huge
quantities of data; recovery management to ensure recoverability of data. The top layer is
storage orchestration which automates work flows to help eliminate human error.

Figure 1-2 Enabling customer to move toward On Demand

Previously we discussed the next steps or entry points into an On Demand environment. The
IBM software products which represent these entry points and which comprise the IBM
TotalStorage Open Software Family is shown in Figure 1-3 on page 4.

Chapter 1. IBM TotalStorage Productivity Center overview 3

Figure 1-3 IBM TotalStorage open software family

1.3 IBM TotalStorage Productivity Center
The IBM TotalStorage Productivity Center is an open storage infrastructure management
solution designed to help reduce the effort of managing complex storage infrastructures, to
help improve storage capacity utilization, and to help improve administrative efficiency. It is
designed to enable an agile storage infrastructure that can respond to On Demand storage
needs.

The IBM TotalStorage Productivity Center offering is a powerful set of tools designed to help
simplify the management of complex storage network environments. The IBM TotalStorage
Productivity Center consists of TotalStorage Productivity Center for Disk, TotalStorage
Productivity Center for Replication, TotalStorage Productivity Center for Data (formerly Tivoli
Storage Resource Manager) and TotalStorage Productivity Center for Fabric (formerly Tivoli
SAN Manager).

Taking a closer look at storage infrastructure management (see Figure 1-4 on page 5), we
focus on four subject matter experts to empower the storage administrators to effectively do
their work.
Data subject matter expert
San Fabric subject matter expert
Disk subject matter expert
Replication subject matter expert


Figure 1-4 Centralized, automated storage infrastructure management

1.3.1 Data subject matter expert: TotalStorage Productivity Center for Data
The Data subject matter expert has intimate knowledge of how storage is used, for example
whether the data is used by a file system or a database application. Figure 1-5 on page 6
shows the role of the Data subject matter expert which is filled by the TotalStorage
Productivity Center for Data (formerly the IBM Tivoli Storage Resource Manager).


Figure 1-5 Monitor and Configure the Storage Infrastructure Data area

Heterogeneous storage infrastructures, driven by growth in file and database data, consume
increasing amounts of administrative time, as well as actual hardware resources. IT
managers need ways to make their administrators more efficient and more efficiently utilize
their storage resources. Tivoli Storage Resource Manager gives storage administrators the
automated tools they need to manage their storage resources more cost-effectively.

TotalStorage Productivity Center for Data allows you to identify different classes of data,
report how much space is being consumed by these different classes, and take appropriate
actions to keep the data under control.

Features of the TotalStorage Productivity Center for Data are:
Automated identification of the storage resources in an infrastructure and analysis of how
effectively those resources are being used.
File-system and file-level evaluation uncovers categories of files that, if deleted or
archived, can potentially represent significant reductions in the amount of data that must
be stored, backed up and managed.
Automated control through policies that are customizable with actions that can include
centralized alerting, distributed responsibility and fully automated response.
Predict future growth and future at-risk conditions with historical information.

Through monitoring and reporting, TotalStorage Productivity Center for Data helps the
storage administrator prevent outages in the storage infrastructure. Armed with timely
information, the storage administrator can take action to keep storage and data available to
the application. TotalStorage Productivity Center for Data also helps to make the most
efficient use of storage budgets, by allowing administrators to use their existing storage more
efficiently, and more accurately predict future storage growth.


TotalStorage Productivity Center for Data monitors storage assets, capacity, and usage
across an enterprise. TotalStorage Productivity Center for Data can look at:
Storage from a host perspective: Manage all the host-attached storage, capacity and
consumption attributed to file systems, users, directories, and files
Storage from an application perspective: Monitor and manage the storage activity inside
different database entities including instance, tablespace, and table
Storage utilization and provide chargeback information.

Architecture
The TotalStorage Productivity Center for Data server system manages a number of Agents,
which can be servers with storage attached, NAS systems, or database application servers.
Information is collected from the Agents and stored in a database repository. The stored
information can then be displayed from a native GUI client or browser interface anywhere in
the network. The GUI or browser interface gives access to the other functions of TotalStorage
Productivity Center for Data, including creating and customizing of a large number of different
types of reports and setting up alerts.

With TotalStorage Productivity Center for Data, you can:
Monitor virtually any host
Monitor local, SAN-attached and Network Attached Storage from a browser anywhere on
the network

For more information refer to the redbook IBM Tivoli Storage Resource Manager: A Practical
Introduction, SG24-6886.

1.3.2 Fabric subject matter expert: Productivity Center for Fabric
The storage infrastructure management for Fabric covers the Storage Area Network (SAN).
To handle and manage SAN events you need a comprehensive tool. The tool must have a
single point of operation and it tool must be able to perform all the tasks from the SAN. This
role is filled by the TotalStorage Productivity Center for Fabric (formerly the IBM Tivoli SAN
Manager) which is a part of the IBM TotalStorage Productivity Center.

The Fabric subject matter expert is the expert in the SAN. Its role is:
Discovery of fabric information
Provide the ability to specify fabric policies
– What HBAs to use for each host and for what purpose
– Objectives for zone configuration (for example, shielding host HBAs from one another
and performance)
Automatically modify the zone configuration

TotalStorage Productivity Center for Fabric provides real-time visual monitoring of SANs,
including heterogeneous switch support, and is a central point of control for SAN
configuration (including zoning). It automates the management of heterogeneous storage
area networks, resulting in”
Improved Application Availability
– Predicting storage network failures before they happen enabling preventative
maintenance
– Accelerate problem isolation when failures do happen


Optimized Storage Resource Utilization by reporting on storage network performance
Enhanced Storage Personnel Productivity - Tivoli SAN Manager creates a single point of
control, administration and security for the management of heterogeneous storage
networks

Figure 1-6 describes the requirements that must be addressed by the Fabric subject matter
expert.

Figure 1-6 Monitor and Configure the Storage Infrastructure Fabric area

TotalStorage Productivity Center for Fabric monitors and manages switches and hubs,
storage and servers in a Storage Area Network. TotalStorage Productivity Center for Fabric
can be used for both online monitoring and historical reporting. TotalStorage Productivity
Center for Fabric:
Manages fabric devices (switches) through outband management.
Discovers many details about a monitored server and its local storage through an Agent
loaded onto a SAN-attached host (Managed Host).
Monitors the network and collects events and traps
Launches vendor-provided specific SAN element management applications from the
TotalStorage Productivity Center for Fabric Console.
Discovers and manages iSCSI devices.
Provides a fault isolation engine for SAN problem determination (ED/FI - SAN Error
Predictor)

TotalStorage Productivity Center for Fabric is compliant with the standards relevant to SAN
storage and management.


TotalStorage Productivity Center for Fabric components
The major components of the TotalStorage Productivity Center for Fabric include:
A manager or server, running on a SAN managing server
Agents, running on one or more managed hosts
Management console, which is by default on the Manager system, plus optional additional
remote consoles
Outband agents - consisting of vendor-supplied MIBs for SNMP

There are two additional components which are not included in the TotalStorage Productivity
Center.
IBM Tivoli Enterprise™ Console (TEC) which is used to receive TotalStorage Productivity
Center for Fabric generated events. Once forwarded to TEC, These can then be
consolidated with events from other applications and acted on according to enterprise
policy.
IBM Tivoli Enterprise Data Warehouse (TEDW) is used to collect and analyze data
gathered by the TotalStorage Productivity Center for Fabric. The Tivoli Data Enterprise
Warehouse collects, organizes, and makes data available for the purpose of analysis in
order to give management the ability to access and analyze information about its
business.

The TotalStorage Productivity Center for Fabric functions are distributed across the Manager
and the Agent.

TotalStorage Productivity Center for FabricServer
Performs initial discovery of environment:
– Gathers and correlates data from agents on managed hosts
– Gathers data from SNMP (outband) agents
– Graphically displays SAN topology and attributes
Provides customized monitoring and reporting through NetView®
Reacts to operational events by changing its display
(Optionally) forwards events to Tivoli Enterprise Console® or SNMP managers

TotalStorage Productivity Center for Fabric Agent
Gathers information about:
SANs by querying switches and devices for attribute and topology information
Host-level storage, such as file systems and LUNs
Event and other information detected by HBAs
Forwards topology and event information to the Manager

Discover SAN components and devices
TotalStorage Productivity Center for Fabric uses two methods to discover information about
the SAN - outband discovery, and inband discovery.

Outband discovery is the process of discovering SAN information, including topology and
device data, without using the Fibre Channel data paths. Outband discovery uses SNMP
queries, invoked over IP network. Outband management and discovery is normally used to
manage devices such as switches and hubs which support SNMP.


In outband discovery, all communications occur over the IP network:
TotalStorage Productivity Center for Fabric requests information over the IP network from
a switch using SNMP queries on the device.
The device returns the information toTotalStorage Productivity Center for Fabric, also over
the IP network.

Inband discovery is the process of discovering information about the SAN, including
topology and attribute data, through the Fibre Channel data paths. In inband discovery, both
the IP and Fibre Channel networks are used:
TotalStorage Productivity Center for Fabric requests information (via the IP network) from
a Tivoli SAN Manager agent installed on a Managed Host.
That agent requests information over the Fibre Channel network from fabric elements and
end points in the Fibre Channel network.
The agent returns the information to TotalStorage Productivity Center for Fabric over the
IP network.
TotalStorage Productivity Center for Fabric collects, co-relates and displays information
from all devices in the storage network, using both the IP network and the Fibre Channel
network. If the Fibre Channel network is unavailable for any reason, monitoring can still
continue over the IP network.

TotalStorage Productivity Center for Fabric benefits
TotalStorage Productivity Center for Fabric discovers the SAN infrastructure, and monitors
the status of all the discovered components. Through Tivoli NetView, the administrator can
provide reports on faults on components (either individually or in groups, or “smartsets”, of
components). This will help them increase data availability for applications so the company
can either be more efficient, or maximize the opportunity to produce revenue.

TotalStorage Productivity Center for Fabric helps the storage administrator:
Prevent faults in the SAN infrastructure through reporting and proactive maintenance, and
Identify and resolve problems in the storage infrastructure quickly, when a problem
Supported devices for TotalStorage Productivity Center for Fabric
Provide fault isolation of SAN links.

For more information about the TotalStorage Productivity Center for Fabric, refer to IBM Tivoli
Storage Area Network Manager: A Practical Introduction, SG24-6848.

1.3.3 Disk subject matter expert: TotalStorage Productivity Center for Disk
The Disk subject matter expert’s job allows you to manage the disk systems. It will discover
and classify all disk systems that exist and draw a picture of all discovered disk systems. The
Disk subject matter expert provides the ability to monitor, configure, create disks and do LUN
masking of disks. It also does performance trending and performance threshold I/O analysis
for both real disks and virtual disks. It also does automated status and problem alerts via
SNMP. This role is filled by the TotalStorage Productivity Center for Disk (formerly the IBM
TotalStorage Multiple Device Manager Performance Manager component).

The requirements addressed by the Disk subject matter expert are shown in Figure 1-7 on
page 11. The disk systems monitoring and configuration needs must be covered by a
comprehensive management tool like the TotalStorage Productivity Center for Disk.


Figure 1-7 Monitor and configure the Storage Infrastructure Disk area

The TotalStorage Productivity Center for Disk provides the raw capabilities of initiating and
scheduling performance data collection on the supported devices, of storing the received
performance statistics into database tables for later use, and of analyzing the stored data and
generating reports for various metrics of the monitored devices. In conjunction with data
collection, the TotalStorage Productivity Center for Disk is responsible for managing and
monitoring the performance of the supported storage devices. This includes the ability to
configure performance thresholds for the devices based on performance metrics, the
generation of alerts when these thresholds are exceeded, the collection and maintenance of
historical performance data, and the creation of gauges, or performance reports, for the
various metrics to display the collected historical data to the end user. The TotalStorage
Productivity Center for Disk enables you to perform sophisticated performance analysis for
the supported storage devices.

Functions
TotalStorage Productivity Center for Disk provides the following functions:
Collect data from devices
The Productivity Center for Disk collects data from the IBM TotalStorage Enterprise
Storage Server (ESS), SAN Volume Controller (SVC), DS400 family and SMI-S enabled
devices. Each Performance Collector collects performance data from one or more storage
groups, all of the same device type (for example, ESS or SAN Volume Controller). Each
Performance Collection has a start time, a stop time, and a sampling frequency. The
performance sample data is stored in DB2® database tables.
Configure performance thresholds
You can use the Productivity Center for Disk to set performance thresholds for each
device type. Setting thresholds for certain criteria enables Productivity Center for Disk to
notify you when a certain threshold has been exceeded, so that you to take action before
a critical event occurs.


You can specify what action should be taken when a threshold-exceeded condition
occurs. The action may be to log the occurrence or to trigger an event. The threshold
settings can vary by individual device.
Monitor performance metrics across storage subsystems from a single console
Receive timely alerts to enable event action based on customer policies
View performance data from the Productivity Center for Disk database
You can view performance data from the Productivity Center for Disk database in both
graphical and tabular forms.
The Productivity Center for Disk allows a TotalStorage Productivity Center user to access
recent performance data in terms of a series of values of one or more metrics, associated
with a finite set of components per device. Only recent performance data is available for
gauges. Data that has been purged from the database cannot be viewed. You can define
one or more gauges by selecting certain gauge properties and saving them for later
referral. Each gauge is identified through a user-specified name, and once defined, a
gauge can be "started", which means it is then displayed in a separate window of the
TotalStorage Productivity Center GUI. You can have multiple gauges active at the same
time.
Gauge definition will be accomplished through a wizard, to aid in entering a valid set of
gauge properties. Gauges are saved in the Productivity Center for Disk database and
retrieved upon request. When you request data pertaining to a defined gauge, the
Performance Manager builds a query to the database, retrieves and formats the data and
returns it to you. Once started, a gauge is displayed in its own window, and displays all
available performance data for the specified initial date/time range. The date/time range
can be changed after the initial gauge widow is displayed.
Focus on storage optimization through identification of best LUN
The Volume Performance Advisor is an automated tool to help the storage administrator
pick the best possible placement of a new LUN to be allocated, that is, the best placement
from a performance perspective. It also uses the historical performance statistics collected
from the supported devices, to locate unused storage capacity on the SAN that exhibits
the best (estimated) performance characteristics. Allocation optimization involves several
variables which are user controlled, such as required performance level and the time of
day/week/month of prevalent access. This function is fully integrated with the Device
Manager function, this is so that when a new LUN is added, for example, to the ESS, the
Performance Manager can seamlessly select the best possible LUN.

For detailed information about how to use the functions of the TotalStorage Productivity
Center for Disk refer to Chapter 6, “TotalStorage Productivity Center for Disk use” on
page 227.

1.3.4 Replication subject matter expert: Productivity Center for Replication
The Replication subject matter expert’s job is to provide a single point of control for all
replication activities. This role is filled by the TotalStorage Productivity Center for Replication.
Given a set of source volumes to be replicated, the Productivity Center for Replication will find
the appropriate targets, perform all the configuration actions required, and ensure the source
and target volumes relationships are set up. Given a set of source volumes that represent an
application, the Productivity Center for Replication will group these in a consistency group,
give that consistency group a name, and allow you to start replication on the application.
Productivity Center for Replication will start up all replication pairs and monitor them to
completion. If any of the replication pairs fail, meaning the application is out of sync, the
Productivity Center for Replication will suspend them until the problem is resolved, resync


them and resume the replication. The Productivity Center for Replication provides complete
management of the replication process.

The requirements addressed by the Replication subject matter expert are shown Figure 1-8.
Replication in a complex environment needs to be addressed by a comprehensive
management tool like the TotalStorage Productivity Center for Replication.

Figure 1-8 Monitor and Configure the Storage Infrastructure Replication area

Functions
Data replication is the core function required for data protection and disaster recovery. It
provides advanced copy services functions for supported storage subsystems on the SAN.

Replication Manager administers and configures the copy services functions and monitors
the replication actions. Its capabilities consist of the management of two types of copy
services: the Continuous Copy (also known as Peer-to-Peer, PPRC, or Remote Copy), and
the Point-in-Time Copy (also known as FlashCopy®). At this time TotalStorage Productivity
Center for Replication supports the IBM TotalStorage ESS.

Productivity Center for Replication includes support for replica sessions, which ensures that
data on multiple related heterogeneous volumes is kept consistent, provided that the
underlying hardware supports the necessary primitive operations. Productivity Center for
Replication also supports the session concept, such that multiple pairs are handled as a
consistent unit, and that Freeze-and-Go functions can be performed when errors in mirroring
occur. Productivity Center for Replication is designed to control and monitor the copy services
operations in large-scale customer environments.

Productivity Center for Replication provides a user interface for creating, maintaining, and
using volume groups and for scheduling copy tasks. The User Interface populates lists of
volumes using the Device Manager interface. Some of the tasks you can perform with
Productivity Center for Replication are:


Create a replication group. A replication group is a collection of volumes grouped together
so that they can be managed concurrently.
Set up a Group for replication.
Create, save, and name a replication task.
Schedule a replication session with the user interface:
– Create Session Wizard.
– Select Source Group.
– Select Copy Type.
– Select Target Pool.
– Save Session.
Start a replication session

A user can also perform these tasks with the Productivity Center for Replication
command-line interface.

For more information about the Productivity Center for Replication functions refer to
Chapter 8, “TotalStorage Productivity Center for Replication use” on page 355.

1.4 IBM TotalStorage Productivity Center
All the subject matter experts, for Data, Fabric, Disk, and Replication are components of the
IBM TotalStorage Productivity Center.

The IBM TotalStorage Productivity Center is the first offering to be delivered as part of the
IBM TotalStorage Open Software Family. The IBM TotalStorage Productivity Center is an
open storage infrastructure management solution designed to help reduce the effort of
managing complex storage infrastructures, to help improve storage capacity utilization, and to
help improve administrative efficiency. It is designed to enable an agile storage infrastructure
that can respond to on demand storage needs.

The IBM TotalStorage Productivity Center allows you to manage your storage infrastructure
using existing storage management products — Productivity Center for Data, Productivity
Center for Fabric, Productivity Center for Disk and Productivity Center for Replication — from
one physical place.

The IBM TotalStorage Productivity Center components can be launched from the IBM
TotalStorage Productivity Center launch pad as shown in Figure 1-9 on page 15.


Figure 1-9 IBM TotalStorage Productivity Center Launch Pad

The IBM TotalStorage Productivity Center establishes the foundation for IBM’s e-business On
Demand technology. We need the function in an On Demand environment to provide IT
resources On Demand - when the resources are needed by an application to support the
customers business process. Of course, we are able to provide resources or remove
resources today but the question is how. The process is expensive and time consuming.

The IBM TotalStorage Productivity Center is the basis for the provisioning of storage
resources to make the e-business On Demand environment a reality. In the future there will
be more automation required to handle the hugh amount work in the provisioning area, more
automation like the BM TotalStorage Productivity Center launch pad provides. Automation
means workflow. Workflow is the key to getting work automated. IBM has a long history and
investment in building workflow engines and work flows. Today IBM is using the IBM Tivoli
Intelligent Orchestrator and IBM Tivoli Provisioning Manager to satisfy the resource requests
in the e-business on demand™ environment in the server arena.

The IBM Tivoli Intelligent Orchestrator and The IBM Tivoli Provisioning Manager provide the
provisioning in the e-business On Demand environment.

1.4.1 Productivity Center for Disk and Productivity Center for Replication
The Productivity Center for Disk and Productivity Center for Replication is software that has
been designed to enable administrators to manage SANs and storage from a single console.
This software solution is designed specifically for managing networked storage components
based on the SMI-S, including:
IIBM TotalStorage SAN Volume Controller
IBM TotalStorage Enterprise Storage Server (ESS)
IBM TotalStorage Fibre Array Storage Technology (FAStT)
IBM TotalStorage DS4000 series
SMI enabled device


Figure 1-10 Managing multiple devices

Productivity Center for Disk and Productivity Center for Replication are built on IBM Director,
a comprehensive server management solution. Using Director with the multiple device
management solution enables administrators to consolidate the administration of IBM storage
subsystems and provide advanced storage management functions (including replication and
performance management) across multiple IBM storage subsystems. It interoperates with
SAN Management and Enterprise System Resource Manager (ESRM) products from IBM,
includingTotalStorage Productivity Center for Data and SAN Management products from
other vendors.

In a SAN environment, multiple devices work together to create a storage solution. The
Productivity Center for Disk and Productivity Center for Replication provides integrated
administration, optimization, and replication features for interacting SAN devices, including
the SAN Volume Controller and DS4000 Family devices. It provides an integrated view of the
underlying system so that administrators can drill down through the virtualized layers to easily
perform complex configuration tasks and more productively manage the SAN infrastructure.
Because the virtualization layers support advanced replication configurations, the Productivity
Center for Disk and Productivity Center for Replication products offer features that simplify
the configuration, monitoring, and control of disaster recovery and data migration solutions. In
addition, specialized performance data collection, analysis, and optimization features are
provided. As the SNIA standards mature, the Productivity Center view will be expanded to
include CIM-enabled devices from other vendors, in addition to IBM storage. Figure 1-11 on
page 17 provides an overview of Productivity Center for Disk and Productivity Center for
Replication.

The Productivity Center for Disk and Productivity Center for Replication provides support for
configuration, tuning, and replication of the virtualized SAN. As with the individual devices,
the Productivity Center for Disk and Productivity Center for Replication layers are open and
can be accessed via a GUI, CLI, or standards-based Web Services. Productivity Center for
Disk and Productivity Center for Replication provide the following functions:
Device Manager - Common function provided when you install the base prerequisite
products for either Productivity Center for Disk or Productivity Center for Replication
Performance Manager - provided by Productivity Center for Disk
Replication Manager - provided by Productivity Center for Replication

Device Manager
The Device Manager is responsible for the discovery of supported devices; collecting asset,
configuration, and availability data from the supported devices; and providing a limited
topography view of the storage usage relationships between those devices.

The Device Manager builds on the IBM Director discovery infrastructure. Discovery of storage
devices adheres to the SNIA SMI-S specification standards. Device Manager uses the
Service Level Protocol (SLP) to discover SMI-S enabled devices. The Device Manager
creates managed objects to represent these discovered devices. The discovered managed
objects are displayed as individual icons in the Group Contents pane of the IBM Director
Console as shown in Figure 1-12 on page 18.


Figure 1-12 IBM Director Console

Device Manager provides a subset of configuration functions for the managed devices,
primarily LUN allocation and assignment. Its function includes certain cross-device
configuration, as well as the ability to show and traverse inter-device relationships. These
services communicate with the CIM Agents that are associated with the particular devices to
perform the required configuration. Devices that are not SMI-S compliant are not supported.
The Device Manager also interacts and provides some SAN management functionality when
IBM Tivoli SAN Manager is installed.

The Device Manager health monitoring keeps you aware of hardware status changes in the
discovered storage devices. You can drill down to the status of the hardware device, if
applicable. This enables you to understand which components of a device are malfunctioning
and causing an error status for the device.

SAN Management
When a supported SAN Manager is installed and configured, the Device Manager leverages
the SAN Manager to provide enhanced function. Along with basic device configuration
functions such as LUN creation, allocation, assignment, and deletion for single and multiple
devices, basic SAN management functions such as LUN discovery, allocation, and zoning
are provided in one step. IBM TotalStorage Productivity Center for Fabric (formerly IBM Tivoli
SAN Manager) is currently the supported SAN Manager.

The set of SAN Manager functions that will be exploited are:
The ability to retrieve the SAN topology information, including switches, hosts, ports, and
storage devices
The ability to retrieve and to modify the zoning configuration on the SAN
The ability to register for event notification, to ensure Productivity Center for Disk is aware
when the topology or zoning changes as new devices are discovered by the SAN
Manager, and when hosts' LUN configurations change


Performance Manager function
The Performance Manager function provides the raw capabilities of initiating and scheduling
performance data collection on the supported devices, of storing the received performance
statistics into database tables for later use, and of analyzing the stored data and generating
reports for various metrics of the monitored devices. In conjunction with data collection, the
Performance Manager is responsible for managing and monitoring the performance of the
supported storage devices. This includes the ability to configure performance thresholds for
the devices based on performance metrics, the generation of alerts when these thresholds
are exceeded, the collection and maintenance of historical performance data, and the
creation of gauges, or performance reports, for the various metrics to display the collected
historical data to the end user. The Performance Manager enables you to perform
sophisticated performance analysis for the supported storage devices.

Functions
Collect data from devices
The Performance Manager collects data from the IBM TotalStorage Enterprise Storage
Server (ESS), IBM TotalStorage SAN Volume Controller (SVC), IBM TotalStorage
DS4000 series and SMI-S enabled devices. The performance collection task collects
performance data from one or more storage groups, all of the same device type (for
example, ESS or SVC). Each performance collection task has a start time, a stop time,
and a sampling frequency. The performance sample data is stored in DB2 database
tables.
Configure performance thresholds
You can use the Performance Manager to set performance thresholds for each device
type. Setting thresholds for certain criteria enables Performance Manager to notify you
when a certain threshold has been exceeded, so that you can take action before a critical
event occurs.
You can specify what action should be taken when a threshold-exceeded condition
occurs. The action may be to log the occurrence or to trigger an event. The threshold
settings can vary by individual device.

The eligible metrics for threshold checking are fixed for each storage device. If the threshold
metrics are modified by the user, the modifications are accepted immediately and applied to
checking being performed by active performance collection tasks. Examples of threshold
metrics include:
Disk utilization value
Average cache hold time
Percent of sequential I/Os
I/O rate
NVS full value
Virtual disk I/O rate
Managed disk I/O rate

There is a user interface that supports threshold settings, enabling a user to:
Modify a threshold property for a set of devices of like type.
Modify a threshold property for a single device.
– Reset a threshold property to the IBM-recommended value (if defined) for a set of
devices of like type.
IBM-recommended critical and warning values will be provided for all thresholds
known to indicate potential performance problems for IBM storage devices.
